Explanation:
a) How much work is done by gravity?
- w = f x d
- w = 950 x 10 x 5.5 = 52250j
b) How much work is done by tension?
- v²=u²+2as
- 0.75²=0.25²+2a x5.5
- 0.56=0.06+2a x5.5
- 2a x5.5 = 0.56 - 0.06
- 2a x 5.5 =0.5
- 11a=0.5
- a = 0.5/11 = 0.05m/s²
w = f x d
w = 950 x 0.05 x 5.5 = 261.25j
Answer:
Yes, the fuse will blow.
Explanation:
We'll begin by converting 50000mA to amperes (A) .this is illustrated below:
1000mA = 1A
Therefore, 50000mA = 50000/1000 = 50A.
From the question given above, the plug can only accommodate 5A. Now if 50000mA i.e 50A is passed through the plug, the plug will blow because the 50A is higher than what the plug can accommodate.
Answer:
The correct answer should be high amplitude : )
Explanation:
A high energy wave is characterized by a high amplitude, a low energy wave is characterized by a low amplitud
The answer is b ( i think don’t quote me)
Answer:
It is displaced.
Explanation:
As the coaster travels. The kinetic and potential energy shifts up and down. But when it shifts, some of the energy is displaced and lost.
