Two north poles would push away from each other
The correct answer would be option B. This is because there is 1500g of gas inside of the balloon so if all of the gas escaped then its mass would decrease by 1500g. It couldn't have decreased by less than 1500g because then that would have to mean that all of the gas didn't escape, which it did. If it decreased by more than 1500g then there would have had to be more than 1500g of gas in the balloon to begin with. This is why the answer would be B. 1500g.
The formula for calculating GPE is
GPE = m x h x g
Where m is mass, h is height raised and g is gravity.
To solve the problem we just have to substitute the values we are given
70,000J = 650 x 10 x y
70,000J = 6500 x y
70,000 / 6500 = y
10.769 = y
So, the block of stone has been raised approximately 10.769 metres.
The answer would be East. Negative particle. if that reads west then the opposite is east.
Answer:
12.5J
Explanation:
Given parameters:
Mass of bucket = 1.7kg
Height = 75cm = 0.75m
Unknown;
Work done on the bucket by the person = ?
Solution:
To solve this problem, we use the work done equation;
Work done = force x distance = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Now, insert parameters and solve ;
Work done = 1.7 x 9.8 x 0.75 = 12.5J
