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:

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.

The distance between Earth and its moon is 3.8×10⁸ m.

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.

Answer:

58.8 N

Explanation:

The normal force is calculated as equal to the perpendicular component of the gravitational force.

Thus; N = mg

We are given m = 6 kg

Thus;

N = 6 × 9.8

N = 58.8 N

Thus, magnitude of normal force on the rock = 58.8 N

Answer:

Explanation: A charged body loses its charge when we touch it with our hand because some of the charge flows through our body to the ground earthing. As a result the charge on the body decreases every time we touch it. This is because of earthing.

Explanation:

Explanation:

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

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

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.

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.

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.

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.

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.

A!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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.
