When we touch a charged body, it loses its charge, due to the process of earthing. Our body is a good conductor of electricity. It transfers the charges to the earth
In order to increase the final momentum of a golf ball, we could
a) follow through when hitting the ball
b) increase the force acting on it
c) increase the time of contact with the ball
d) swing as hard as possible
f) All of the above
Answer:
option f) all of the above
We will see that all of the given options would increase the momentum, so the correct option is f "all of the above"
How to increase the momentum?
Momentum is defined as the amount of motion, and it is given by:
P = m*v
Where m is the mass of the object and v is the velocity.
We can't change the mass of the golf ball, but we can change the velocity, and to do it, we need to increase the acceleration that we apply to the ball.
To increase the acceleration we can:
follow through when hitting the ball (the force is applied for more time, so the acceleration is larger).increase the force acting on it (it directly increases the acceleration).increase the time of contact with the ball (similar to the first option).swing as hard as possible (similar to the second option).Then all the options are correct, which means that the correct option is f.

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
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.

Name two devices we use generators in. Describe how they work.
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.
. Rohit had only one light source in his room. He was told by his friend that he can make the room more lighted by using mirror. What type of mirror can be used for the purpose?
Answer:
very smooth and polished glass mirror
Explanation:
The best type of mirror for this would be a very smooth and polished glass mirror. A metal mirror will also work but it would need to be extremely polished. This would allow light to efficiently be reflected across the room, thus effectively adding an "extra" light source to the room. If the mirror is not smooth then the light may become distorted and not reflect properly as it is supposed to. This may defeat the entire purpose of the mirror for this scenario.

What is centripetal force?
A force that causes a body to follow a curved path is known as a centripetal force. It always moves in a direction that is the opposite of the body's velocity and in the direction of the immediate center of curvature of the path.
It is "a force by which bodies are dragged or driven, or in any manner tend, towards a point as to a center," according to Isaac Newton.
Given parameters:
Mass of the Earth: M = 6.0 × 10²⁴ kg.
Mass of the moon: m = 7.3 × 10²² kg.
Moon's tangential speed: v = 1,025 m/s
Let the distance between the center of Earth and the moon is r.
Hence,
GMm/r² = mv²/r
r = GM/v²
= 6.7 × 10 ⁻¹¹ × 6.0 × 10²⁴ / (1,025)²
= 3.82×10⁸ m.
Hence, by subtracting Earth's radius = 6.4 x 10⁶ m, we get, the distance between Earth and its moon is 3.8×10⁸ m.

Five independent measurements are made of the diameter of a cylinder. Results, in mm, are: 21.8; 21.6; 22.1; 21.9; 22.1. What should be the reported value of the cylinder's diameter?
Answer: 21.9 mm
Explanation:
Given that five independent measurements are made of the diameter of a cylinder. Results, in mm, are: 21.8; 21.6; 22.1; 21.9; 22.1. What should be the reported value of the cylinder's diameter?
The measurement of the diameter of cylinder is measured several time in order to reduce the uncertainty called random error.
The reported value of the cylinder's diameter should be the average or the mean value of the whole measurement.
That is
Mean = (21.8 + 21.6 + 22.1 + 21.9 + 22.1) ÷ 5
Mean = 109.5 ÷ 5
Mean = 21.9 mm
Therefore, the reported value of the cylinder diameter will be 21.9 mm

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
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.

1) A 2.5 kg ball strikes a wall with a velocity of 8.5 m/s to the left. The ball bounces off with a
velocity of 7.5 m/s to the right. If the ball is in contact with the wall for 0.25 s, what is the
constant force exerted on the ball by the wall?
Answer:
Force = -10 Newton.
Explanation:
Given the following data;
Initial velocity = 8.5m/s
Final velocity = 7.5m/s
Time = 0.25 seconds
Mass = 2.5kg
To find the force exerted;
First of all, we would determine the acceleration of the ball;
Acceleration = (v - u)/t
Acceleration =(7.5 - 8.5)/0.25
Acceleration = -1/0.25
Acceleration = -4 m/s²
Now, to find the force exerted;
Force = mass * acceleration
Force = 2.5 * -4
Force = -10 Newton
Note: The force is negative because it is an opposite reaction.
What name is given to the turning effect of a force?
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.

Answer:
I started answering this before everything was erases, but briefly
W = 1/2 K x^2 so K = 2 W / x^2 = 6 * 25 = 150
Also F = - K X = 150 * 1/5 = 30 N at max extension
m = F / a = 30 /15 = 2 kg
Since max extension occurs at t = 0 you can write
x = A sin ω t
v = ω A cos ω t
a = -ω^2 A sin ω t note that there is no phase angle here
Also at .1 compression
.1 = .2 sin ω t and sin ω t = 1/2 and ω t = 30 deg = pi / 6
Substiture these values above to get velocity and acceleration when
ω t = 30 deg
