Explanation:
Given that,
Work done to stretch the spring, W = 130 J
Distance, x = 0.1 m
(a) We know that work done in stretching the spring is as follows :
(b) If additional distance is 0.1 m i.e. x = 0.1 + 0.1 = 0.2 m
So,
So, the new work is more than 130 J.
Answer:
To write 50000 in scientific notation, we will have to move the decimal point four points to left, which literally means dividing by 104 . Hence in scientific notation 50000=5×104 (note that as we have moved decimal four points to left and thus divided by 104 , we are multiplying by 104 to compensate.
Explanation:
By putting an apple up on high ground. (That is 1 example)
This creates a higher gravitational force, and when it falls down it would have a lot of kinetic energy. But, if put on low ground, it wouldn't have enough potential energy to increase the kinetic energy.
