The top pair of pliers failed to loosen a stubborn bolt, but the bottom pair successfully removed it. Because the contact between the bolt and the   pliers working surface is less.

Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtained efficiency of the given mechanical machine.

The efficiency to open the stubborn bolt depends upon the contact between the working surface of the pliers and the bolt.

The contact between the bolt and the top pair of pliers working surface is less. Its mechanical advantage is less.

Hence, the top pair of pliers failed to loosen a stubborn bolt, but the bottom pair successfully removed it.

Explanation:

The magnitude of the gravitational force exerted on the satellite by the planet  will be F = 11970.1 N

The gravitational force is a force that attracts any two objects with mass.It is directly proportional to the masses and inverse of the distance between the two objects.

It is given that,

Mass of the satellite, m = 2400 kg

Speed of the satellite, v = 6670 m/s

Radius of the circular path,

Let F is the magnitude of the gravitational force exerted on the satellite by the planet. The centripetal force is equal to the gravitational force. It is equal to :

[tex]F=\dfrac{mv^2}{r}[/tex]

[tex]F=\dfrac{2400\times (6670)^2}{8.92\times 10^6}[/tex]

F = 11970.1 N

So, the magnitude of the gravitational force exerted on the satellite by the planet is 11970.1 N. Hence, this is the required solution.

Answer:

Because it can desolve many many things.  

Explanation:

The electric potential at a distance from a nucleus of charge 50e is 144 Volts.

The potential is the work done by the test charge to move it from infinity to a particular point.

The potential is given by the relation

V = kQ / r

The distance of a point from the nucleus is 5.0 × 10⁻¹⁰ m and the charge on the nucleus is 50 e = 50 × 1.9 × 10⁻¹⁹ C.

k = 9 × 10⁹ kg-m²/s²-C²

Here, Q is the charge, r is the distance and k is the constant.

Substituting the value into the equation and solving, we get

V = 144 Volts

Thus, the potential at a distance from a nucleus of charge 50e is 144 Volts.

A moonbow is occurred due to reflection and refraction of moonlight.

A moonbow also known as a lunar rainbow. It is the phenomenon occurs when the moonlight is refracted through water droplets in the air. The amount of light available from the full moon is very less than that produced by the sun. So, the moonbows are the type of rainbow, produced by the moonlight refraction and reflection through water droplets. Moonbows are fainter than rainbows.

Thus, a moonbow is occurred due to reflection and refraction of moonlight.

Answer:

Push-ups. Let M1 be the mass of the body and M2 be the mass of weights. Assume that M1 must be heavier than M2. Since M1 is heavier, M1 requires more force, and therefore work to be applied, let F1=M1*g. To bring our body back up, we need a force bigger or equal (if already in motion) to F1.

Let F2 = M2*g

Since F1 has to be bigger than F2 due to mass, we can build an equation for energy. Let X be a displacement, which is equal in both situations. Constructing a change of energy equation we can see that work done to lift the body is greater:

W1=F1*x

W2=F2*x

Where W1 is the work of the hands-on body, and W2 is the work of lifting weights. W1 has to be larger than W2. Since more work in W1, more muscle will be needed to complete a repetition, but only assuming that M1 > M2.

If the forces on an object are greater than zero,the object will definitely in the motion. This concept in accordance with law of inertia.

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

Newton's law of inertia states that a body wants to continue its motion until the external force is not acted on it.

Hence, if the force is grater than zero, the body will be in motion.

The electric field strength created by a charge decreases with increasing distance from the charge. The relationship between the electric field strength (E) and the distance (r) from the charge is given by the inverse square law:

E ∝ 1/r^2

Let's consider the given scenario:

At a distance of 40 cm (0.4 m) from the charge, the electric field strength is measured as 8 N/C.

We want to determine the electric field strength at a distance of 80 cm (0.8 m) from the charge when the charge is reduced to 1/2 Q.

First, we can set up a proportionality based on the inverse square law:

(E1)/(E2) = (r2^2)/(r1^2)

Substituting the given values:

8/E2 = (0.8^2)/(0.4^2)

Simplifying the equation:

E2 = 8 * (0.4^2)/(0.8^2)

E2 = 8 * 0.16/0.64

E2 = 2 N/C

Therefore, at a distance of 80 cm from the charge, when the charge is reduced to 1/2 Q, the electric field strength would be 2 N/C.

The strength of an electric field depends on the magnitude of the charge creating the field and the distance from the charge. In this case, since the charge is reduced to 1/2 Q, the electric field strength is also halved.

Additionally, as we move twice as far away from the charge (from 40 cm to 80 cm), the electric field strength decreases according to the inverse square law. As a result, the electric field strength is reduced to 2 N/C at a distance of 80 cm.
