Answers
The image formed is inverted. From the ray diagram, the object and image are on same side of the mirror. Thus, the imaged formed is real.
What is Inverted Image?
A section of physics called optics studies how light behaves and interacts with objects. Lenses are curved, transparent structures that are often constructed of glass and are used for focussing or dispersing light.
A convex lens is the opposite of a concave lens. Light rays converge in convex lenses as opposed to concave lenses. The convex lens converges incident rays towards its central axis because, in contrast to the concave lens, it is larger in the middle and thinner at the corners.
The edges of the convex lens are curled outward rather than inward. When the light is intensely focused beyond the focal length of the lens, the image appears smaller and inverted.

The magnitude of charge A is half the magnitude of charge B. However, the electrostatic force experienced by charge A and by charge B is the same. It can be concluded that the electric field strength of charge A is ________ the electric field strength of charge B. one-fourth one-half two times four times
Answers
Answer:
Qb = 2 Qa magnitude of charge on B is twice that of A
F = K Qa * Qb / R^2 both charges experience the same force
Ea = K Qa / s^2 field strength of A at distance S
Eb = K Qb / s^2 field strength of B at distance S
The electric field strength of B is twice that of A
That means that charge on A is 1/2 that on B for the forces on each to be the same:

Does an electric field affect compasses?Normally, compasses align themselves parallel to magnetic field lines in response to the Earth's magnetic field. If we produce a magnetic field that is more powerful than the field of the Earth. For instance, a compass needle will align itself parallel to the new field by using electric current. Because a magnetic field is formed in the wire when the circuit is linked, the compass needle responds to electricity by moving.
What occurs when a compass is placed close to an electric current?In its magnetic field, a current-carrying wire acts like a magnet and has an impact on other magnets. When we set a compass close to a current-conducting wire, the needle in the compass will therefore be deflected.

1. A 1.15-kg block is released from rest on a frictionless inclined plane. The inclined plane forms an angle of 35° with the
ground. The block slides down the inclined plane and compresses a spring at the bottom by 3.5 cm and stops momentarily.
If 334 N are required to compress the spring by 2.4 cm, what distance has the block travelled?
>
Answers
Answer:
Explanation:
We can use the work-energy principle to solve this problem. The work-energy principle states that the work done on an object is equal to the change in kinetic energy of the object.
We can begin by finding the spring constant (k) of the spring. The spring constant is the force required to compress a spring by a certain distance. We can use the information given to us in the problem to find the spring constant:
k = F / x = 334 N / 0.024 m = 13,916.67 N/m
Now we can use the spring constant, the compression distance (3.5 cm) and the mass of the block (1.15 kg) to find the work done on the block as it compresses the spring:
work = 1/2 * k * x^2 = 1/2 * 13,916.67 N/m * (0.035 m)^2 = 97.4 J
Since the block is released from rest, its initial kinetic energy is zero. So, the work done on the block as it compresses the spring is equal to its final kinetic energy.
We know that the block slides down on a frictionless incline, so we need to consider the work done by gravity on the block during its motion. The work done by gravity is given by the equation:
work = force * distance * cos(theta)
where force is the force of gravity acting on the block, distance is the distance the block slides down the incline and theta is the angle of the incline with the ground.
force = m * g , where m = 1.15 kg and g = 9.8 m/s^2
distance = s
theta = 35°
substituting the values
work = (1.15 kg * 9.8 m/s^2) * s * cos(35°)
Now we can add the work done by gravity to the work done by the spring to find the total work done on the block.
work = 97.4 J + (1.15 kg * 9.8 m/s^2) * s * cos(35°) = 97.4 J + (11.37 N) * s * cos(35°)
Now we can solve for s, the distance the block travelled.
s = (97.4 J) / (11.37 N * cos(35°))
The final answer will be in meters.

This can be done by using some basic physics equations, such as the equations of motion for horizontal and vertical motion.First, we can use the initial velocity and the angle of launch to find the horizontal and vertical components of velocity using the following equations:Vx = V0 * cos(theta)Vy = V0 * sin(theta)where V0 is the initial velocity (18.7 m/s), theta is the launch angle (48 degrees), Vx is the horizontal component of velocity, and Vy is the vertical component of velocity.Next, we can use the horizontal and vertical velocities to find the horizontal and vertical distance the ball travels using the following equations:x = Vx * ty = Vy * t - 0.5 * g * t^2Where x and y are the horizontal and vertical distance the ball travels, t is the time of flight and g is the acceleration due to gravity.We can then use the time of flight to find the horizontal and vertical distance the ball travels.Finally, we can compare the height of the goal post (3.05 m) to the vertical distance the ball travels. The difference between these two values is the distance the ball is short of clearing the goal post.After solving the above equations we get the ball is 0.16 meters short of clearing the goal post.To learn more about horizontal motion refer:

The drawing shows a device that can be used to measure the speed ofa bullet. The device consists of two rotating disks,separated by a distance of d = 0.850 m, and rotating with anangular speed of 95.0 rad/sec. The bullet first passesthrough the left disk and then through the right disk. It isfound that the angular displacement between the two bullet holes isθ = 0.240 rad. From these data, determine thespeed of the bullet.
Answers
V = 336.46 m/sec is the speed of the bullet .
What is displacement ?
Displacement in mechanics. The distance a particle or object travels in a particular direction. Particles and bodies are usually treated as point masses. That is, without loss of generality, an object can be treated as if all its mass were concentrated at one mathematical point. In the figure, A is the start position of the point, B is the end position, and the straight line from A to B is the displacement. The distance a point moves depends on the path it follows. Equals the amount of displacement only if the path is straight. In mechanics, it is often necessary to distinguish between the distance a point moves (or the distance a force acts) and the displacement of a point or force. Displacement is a vector quantity because it has both magnitude and direction.
Let speed of bullet be "V". Then we have:
{Speed Of Bullet} = V
{Time For Bullet To Travel
Distance "d" Between Rotating Disks} = T =
= d/V
= (0.850 m)/V
= (0.850)/V (<---Eqn #1)
{Disk Rotational Speed} = ω = 95.0 rad/sec
{Angular Displacement Between Bullet Holes} = θ = 0.240 rad
{Time Between Successive Disk Bullet Holes} = T =
= θ/ω
= (0.240)/(95.0)
= 0.002526315 sec (<--- Eqn#2)
We now equate Eqn #1 & #2, and solve for "V":
(0.850)/V = 0.002526315
----> V = (0.850)/(0.002526315)
----> {Bullet Velocity} = V = 336.46 m/sec

A light bulb operating at 110 V draws 1.40 A of current. What is its resistance?
Answers
The value of resistance for given current and potential difference is 78.6 ohm.
The obstruction to current flow in an electrical circuit is measured by resistance. The Greek letter omega () represents the unit of measurement for resistance, known as ohms.
The ratio of the electric current flowing through it to the voltage applied is the definition of electrical resistance for a circuit component or device: Ohm's law, I = V/R, can be used to anticipate the behavior of the material if the resistance remains constant over a wide range of voltage.
V = 110
VI = 1.4 A
The voltage in this case is V, while the current is I.
Write the voltage expression based on Ohm's law, then rearrange the terms to arrive at the resistance expression, R. The value of R can then be calculated by substituting the necessary numbers.
V = I R
R = V / I
R = 110 / 1.40
R = 78.6 ohm
Here, 78.6 ohm is the measured value of resistance. As a result, choice B is accurate.

When studying the properties of light, for example, reaction time would not matter much. Light moves at such a fast rate that reaction time has no effect on the results of experiments measuring the speed of light, the reflection of light, or any other property related to light.
What is reflection?
Reflection is when a wave, such as a light wave or sound wave, bounces off a surface and returns to the source. This happens when the wave encounters an obstacle such as a wall or other barrier, and the wave is redirected back towards the source. Reflection is one of the fundamental principles of physics, and is used to explain many phenomena such as the fact that light is reflected off of a mirror. Reflection is also used to help explain phenomena such as sound reverberation and the formation of shadows.
What is sound reverberation ?
Sound reverberation is the effect created when a sound is reflected off of surfaces in a room or area. This effect is created when the sound bounces off of walls, ceilings, and other objects, and then is heard again by the listener. This creates an echo-like effect, and can be used to create a more acoustically ‘live’ sound.

Answers
√2 times is the compression of the spring if the mass of the block is halved and its speed is doubled.
What is mass?
Mass is a unit used in physics to describe inertia, a fundamental property of all matter. It essentially refers to the resistance a mass of matter provides to a change in its speed or location brought on by the application of a force. The amount of the body's mass determines how much of a change an applied force produces.
What is speed ?
A shift in an object's location, either in direction or speed. How fast something is travelling is determined by how far it has travelled in relation to how long it took. Speed is considered a scalar quantity because it only has a direction and no magnitude.
let the compression in the spring be x
kE of block becomes PE of spring
1/2 * mv^2 = 1/2 * kx^2
x = v√(m/k)

Stress is the force applied perpendicular to the surface of an object in keeping with the unit location over which that force is shipped. Gauge strain is the strain relative to the ambient strain. Numerous gadgets are used for the specific strain. strain is defined to be the quantity of pressure exerted per location.
The pascal (Pa) is the same old unit of stress. A pascal is a very small quantity of stress, so the most beneficial unit for normal gasoline pressures is the kilopascal (kPa). A kilopascal is equal to a thousand pascals. Another usually used unit of pressure is the atmosphere (atm).strain is commonly measured in units of pressure in step with a unit of surface vicinity ( P = F / A). In bodily technological know-how, the image for strain is p and the SI unit for measuring stress is the pascal (image: Pa). One pascal is the pressure of one Newton consistent with a square meter appearing perpendicular on a floor.

Complete Question:
During forced exhalation, such as when blowing up a balloon, the diaphragm and chest muscles create a pressure of 60.0 mm Hg between the lungs and chest wall. What force in newtons does this pressure create on the 600 cm2 surface area of the diaphragm?
This pressure exerts a 4.802 N force on the 600 cm2 surface area of the diaphragm.
The force delivered perpendicularly to an object's surface in accordance with the unit location across which that force is distributed is known as stress. The strain in relation to the ambient strain is known as gauge strain. There are several tools utilised for the particular strain. The amount of pressure applied to each site is referred to as strain.
The traditional unit of stress is the pascal (Pa). The kilopascal is the ideal measure for regular fuel pressures since a pascal is a relatively modest amount of tension (kPa). One thousand pascals is equivalent to one kilopascal. The atmosphere is another frequently used unit of pressure (atm). Pressure units along with a unit of surface proximity are widely used to quantify strain (P = F / A). In physical technology, the SI unit for measuring stress is the pascal, and the image for strain is p. (image: Pa). The pressure of one Newton equivalent to a square metre appearing perpendicular to the ground is one pascal.

A force of 50 N acts on an object weighing 25 N for 5 seconds. Find the change in velocity of the object.
Answers
Force = 50N
Weight = Mass × Gravity = 25
Mass = 25 ÷ 10 = 2.5Kg
Time = 5 Seconds
we know
Force = mass × acceleration
50 = 2.5 × Velocity ÷ Time
50÷2.5 = Velocity ÷ 5
Velocity = 250 ÷ 2.5
Velocity = 100m/s.
Answer:
100m/s
Explanation:
force(f) = 50N
weight = 25N
weight = mass × gravity
25 = m × 10
25 = 10m
m = 25/10
m = 2.5kg
time(t) = 5sec
impulse formula
ft = m(∆v)
by substituting
50 × 5 = 2.5∆v
250 = 2.5∆v
∆v = 250/2.5
∆v = 100m/s

What are electric flux and its measure?Although an electric field cannot flow by itself, electric flux in electromagnetism is a measure of the electric field passing through a certain surface. Any place in space where there is an electric charge will be affected by the electric field E. The gradient of the potential is the electric field. The distribution of the electric field or the velocity at which the electric field moves through a specific area can both be measured as electric flux. The Greek letter e is used to represent electric flow. Electric flux is measured in SI units as or Nm 2 C – 1.
