OA the speed will increase four times
Answer:
the speed of 0.10 sphere when it is moved to 0.20 kg to the left is : 
Explanation:
Using the expression of the Change in Gravitational Potential Energy:

So when the sphere exerts just 10 kg mass; the change in the gravitational potential energy is :



the change in the gravitational potential energy when the sphere exerts just 5 kg mass is ;



The net total change is:



We all know that for there to be a balance ;loss of gravitational potential energy must be equal to the gain in kinetic energy .
SO;
K.E = 



v = 
Thus, the speed of 0.10 sphere when it is moved to 0.20 kg to the left is : 
Answer:
3 m/s east
Explanation:
I took a test a got it right
Answer:
Michael is heavier.
Explanation:
If Michael is 104 pounds, that is equal to 47 kg.
Erica is 44 kg which is 97 pounds.
104 is greater than 97, and 47 is greater than 44.
