W = M g = 150 kg * 9.81 m/s^2 = 1470 N

You were only given 3 significant figures in the question.

The weight of the box is 1471.5 N.

In science and engineering, an object's weight is defined as the force of gravity acting on the thing. Weight is sometimes described as a vector quantity in common textbooks, denoting the gravitational force acting on the item.

Given parameters:

Mass of the box, m = 150 kg.

Acceleration due to gravity, g = 9.8 m/s².

Hence, weight of the box is, W = mg = 150 kg × 9.81 m/s² =1471.5 N.

SO, weight of the  box with a mass of 150 kg on Earth is 1471.5 N.

Work done by a force is given as the product of force and the distance moved by the force.

Work done is the product of force and the distance moved by the the force.

Thus, distance required by the 100 N force is given as:

Distance = 1000/100 = 10 m

Distance to be moved is 10 m.

Force applied = work done/ distance

Force applied by the hoist = 500/2

Force applied by the hoist = 250 N

Distance moved in one push-up = 25 cm = 0.25 m

Work done by the athlete after one push-up = 250 × 0.25 m

Work done by the athlete = 62.5 J

Distance moved by the force = 0 m

Work done = 500 × 0 = 0 N

Therefore, for work to be done, force has to move a distance.

Answer:

the electric and magnetic fields that make up an electromagnetic wave are perpendicular (at right angles) to each other. Both fields are also perpendicular to the direction that the wave travels. Therefore, an electromagnetic wave is a transverse wave.

Explanation:

Answer:

W = F * S     one does not know the work performed because one does not know what force produced the resulting work. Neither can one calculate the power required because P = W / t  (work / time)

One only knows the distance and the time but not the force required.

Explanation:

There are a few explanations as to why. I'm not sure as to what level of an explanation you are looking for. A person's body is made of atoms, which have constant motion due to multiple processes. An atom can never ever be frozen to absolute zero motion, we can only approach that value. Therefore, we will always have kinetic energy. Another explanation is Einstein's famous formula E = mc^2. This is the rest mass energy, which all things with mass obey. There is an energy-mass equivalence.

The energy of the ball at its highest position is potential energy.

The law of conservation of energy states that, energy can neither be created nor destroyed. Despite this, it is capable of changing its form. The sum of the energies in an isolated system is constant regardless of the types of energy present.

Here,

According to law of conservation of energy, at each position of the ball, it will have some amount of energy.

At point A

The ball is at its highest position, that means maximum height. So, the energy of the ball at that position is potential energy and it doesn't have any kinetic energy.

At points B and C

At these positions the ball is moving downwards. That means the potential energy is being converted into kinetic energy of the ball. So, it has both PE and KE.

At point D

The ball is at the lowest position, on the ground. So, the potential energy is zero. Therefore, it has the kinetic energy.

At points E and F

At these positions, the ball is moving upwards. So, it has both PE and KE.

Hence,

The energy of the ball at its highest position is potential energy.

Answer:

  cue ball final: 0.85 m/s at N65°W

  8-ball final: 1.27 m/s at N12°E

Explanation:

In a perfectly elastic collision, both momentum and energy are conserved. The momentum is the sum of products of mass and velocity. The energy is half the product of mass and the square of velocity. The difference of "particle" velocities changes sign as a consequence of the collision.

__

If we let the masses be m1 and m2, the corresponding initial velocities be v1 and v2, and the final velocities be u1 and u2, we have ...

  m1·u1 +m2·u2 = m1·v1 +m2·v2 . . . . . . . conservation of momentum

  u1 -u2 = v2 -v1 . . . . . . . . . . . . . . . relative velocity sign changes

This pair of linear equations can be solved for u1 and u2 in any of the usual ways to give ...

  u1 = v1(m1 -m2)/(m1 +m2) + v2(2·m2)/(m1 +m2)

  u2 = v2(m2 -m1)/(m1 +m2) +v1(2·m1)/(m1 +m2)

__

Using angle measures as clockwise from north, we are given ...

  cue ball: m1 = 0.17 kg, v1 = 1.2∠10° m/s

  eight ball: m2 = 0.15 kg, v2 = 0.89∠-70° m/s

A suitable calculator can find the final velocities using the above equations.

The first attachment shows the calculations using a TI-84 work-alike calculator.

  cue ball final: 0.85 m/s at N65°W

  8-ball final: 1.27 m/s at N12°E

The hot summer cottage she left in September will still be hot when she returns in June as long as no one enters it (Isolated).

The second law of thermodynamics states that, hot things always cool unless you do something to stop them. Or the total entropy of an isolated system can never decrease.

In other words, not all heat energy can be converted into work in a cyclic process.

Therefore, we can conclude that when the woman returns, the hot summer cottage she left in September will still be hot when she returns in June as long as no one enters it (Isolated).

Answer:

option 3 potential chemical energy

(a) When the voltage increases, the electric field increases, and vice versa.

(b) When the distance of the charge increases, the electric field strength decreases, and vice versa.

The direction of the electric field depends on the direction of the positive charge, electric field is always directed opposite to positive charge.

The potential of a unit charge is the product of the electric field strength and the distance of the charge.

V = Ed

E = V/d

Thus, when the voltage increases, the electric field increases, and when the voltage decreases, the electric field decreases.

Also, when the distance of the charge increases, the electric field strength decreases, and the distance decreases, the electric field strength increases.
