Answer:

Explanation:
The torque of a force is given by:

where
F is the magnitude of the force
d is the distance between the point of application of the force and the centre of rotation of the system
 is the angle between the direction of the force and d
 is the angle between the direction of the force and d
In this problem, we have:
 , the force
, the force
 , the distance of application of the force from the centre (0,0)
, the distance of application of the force from the centre (0,0)
 , the angle between the direction of the force and a
, the angle between the direction of the force and a
Therefore, the torque is

Answer:

Explanation:
The correct equation follows the law of conservation of energy where kinetic energy is all transformed to potential energy, since we know that kinetic energy is expressed as
 while potential energy is mgh where m is the mass of the object, v is the velocity or speed of the object, g is acceleration due to gravity and h is the vertical height. Therefore, relating the two equations we should have

The answer to your question will be C. because they are very inexpensive and are readily available but they will eventually deplete because we use them faster than they can be produced we use what has been building up.
