Answer:
Hey buddy, here is your answer. Hope it helps you.
Explanation:
Yes, weight of a body is not constant, it varies with the value of acceleration due to gravity, g. Weight of a body is zero, when it is taken to the centre of the earth or in the interplanetary space, where g=0. Mass is the total matter in a body, while weight is the force by which the body is attracted.
Weight is never constant while mass is. So we can have weight zero but with some mass. This will happen when an object is at the centre of earth, as g=0 at centre of earth , so weight will be 0 while mass will always be constant everywhere
Explanation:
Given mass of the object is 1200kg and it's placed at a height of 45m above the ground. As we know that potential energy is ,
where,
- m is the mass of the body .
- g is acceleration due to gravity.
- h is the height above the ground .
Substituting the respective values ,

Multiply ,
<u>Hence</u><u> the</u><u> </u><u>potential</u><u> energy</u><u> is</u><u> </u><u>5</u><u>4</u><u>0</u><u>0</u><u>0</u><u>0</u><u>J</u><u> </u><u>.</u>

Answer:
1.Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
Answer:
<h2>Newton Second low say" the acceleration of a body id directly proportional to the force acting on the body and inversly proportional to tje mass of the body "</h2>
Explanation:
Newton's second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. ... Newton's second law is one of the most important in all of physics.
