From an apple tree 2 metres high, a 100g mass apple fell of the tree, what work did it do?

Answers

Answer 1

Answer:

When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.

A wave frequency of 440 Hz travels through a medium at 343 m/s. Calculate the wavelength
for this wave.
150,920 m
1.28 m
97 m
0.078 m

Answers

Answer:

0.78 m

Explanation:

us the formula

speed = frequency x wavelength

343 = 440 x wavelength

343 / 440 = wavelength

wavelength = 0.78 m

I think the last option, you wrote wrongly, it is supposed to be 0.78 not 0.078 .

if you think I am wrong please do tell me, I will redo this.

The graph shows the amplitude of a passing wave over time in seconds (s) What is the approximate frequency of the wave shown? A. 6 Hz B. 0.2 0.4 Hz

Answers

Answer:

0.2 I took the test

Explanation:

I took the test

The time period of the whole wave cycle is 6 seconds but the time period of one complete wave is about 4 seconds here. The inverse of this time period is the frequency, that is 0.2 Hz.

What is frequency ?

Frequency by definition is the number of events per unit time. Frequency of a wave is the number of wave cycles in one second. It is the inverse of the time period.

Frequency is directly related to the energy of the wave. As the frequency increases, energy of the wave also increases. In the given graph the wave cycle is given for a time of 6 seconds.

The time period for one complete wave  is 4 second from the graph.

thus, T = 4 s

v =  1/T

  = 1/4 = 0.2 s⁻¹ or 0.2 Hz  

Therefore, the frequency of the wave shown, is 0.2 Hz.

What is mass? (Specific simple answer)

Answers

Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The grater the mass of a body, the smaller the change produced by an applied force.

Answer:

Mass is the quantity of substance in an object

A force of 900 N pushes a wedge 0.10 m into a log. If the work done on the log is 50 J, what is the efficiency of the wedge?
HELPPPP

Answers

Answer:

55.56%

Explanation:

We'll begin by calculating the work done in pushing the wedge. This can be obtained as follow:

Force (F) = 900 N

Distance (s) = 0.1 m

Workdone (Wd) =..?

Wd = F × s

Wd = 900 × 0.1

Wd = 90 J

Finally, we shall determine the efficiency. This can be obtained as follow:

Work output = 50 J

Work input = 90 J

Efficiency =?

Efficiency = work output / work input

Efficiency = 50 / 90 × 100

Efficiency = 55.56%

Thus, the efficiency is 55.56%

A car manufacturer wants to change its car’s design to increase the car’s acceleration. Which changes should the engineers consider making to the design? increase the force that the engine provides decrease the force that the engine provides increase the mass of the car decrease the mass of the car increase the top velocity the car can travel decrease the top velocity the car can travel

Answers

Answer:

I. increase the force that the engine provides.

II. decrease the mass of the car

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

[tex] Acceleration = \frac {Force}{mass} [/tex]

In this scenario, a car manufacturer wants to change its car’s design to increase the car’s acceleration. Thus, the changes the engineers should consider making to the design is to increase the force that the engine provides and decrease the mass of the car.

Answers:

2) 7.5 times heavier than air and more than 100 times heavier than hydrogen. The gas liquefies at −61.8 °C (−79.2 °F) and freezes at −71 °C (−96 °F). On further cooling, solid radon glows with a soft yellow light that becomes orange-red at the temperature of liquid air (−195 °C [−319 °F]).

How long will it take for a basketball spinning on someone’s finger to stop if it undergoes and angular acceleration of -0.15 rad/s and is traveling at 27 rad/s initially? How many revolutions will it make?

Answers

The basketball's angular velocity ω at time t is

ω = 27 rad/s + (-0.15 rad/s²) t

It comes to a stop when ω = 0, which happens for

0 = 27 rad/s - (0.15 rad/s²) t

t = (27 rad/s) / (0.15 rad/s²)

t = 180 s

In this time, the ball would undergoes an angular displacement θ of

θ = (27 rad/s) t + 1/2 (-0.15 rad/s²) t ²

Plug in t = 180 s and solve for θ :

θ = (27 rad/s) (180 s) - 1/2 (0.15 rad/s²) (180 s)² = 2430 rad

One complete revolution corresponds to a turn of 2π rad, so the ball makes

(2430 rad) / (2π rad/rev) ≈ 386.747 rev

or about 387 revolutions as it slows down.


What name is given to the turning effect of a force?

Answers

Answer:

The turning effect of a force is known as the moment. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn. When undoing a nut fastened to a screw by hand one realises that the amount of force required is a lot greater than when undoing the same nut using a spanner.

Name two devices we use generators in. Describe how they work.

Answers

Answer:

There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.

Explanation:

An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. ... Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

Answers

Answer:

Newton's law of gravitational holes good irrespective of the nature of two bodies., i.e., big or small, at all times, at all locations and for all distances in the universe.

Explanation:

It is called so because it is applicable on all bodies having mass, and the bodies will be governed by the same law, that is newton's law of gravitation. Thus, as it is applicable universally, it is called as universal law.

It’s called “Universal law” because it pretty much applies across the whole universe
