Answer:
So first determine how many times does 5 go into 100.
100/5=20
Thus in 100 seconds the boy would have traveled a distance of 10 meters 20 times.
10*20=200
If the boy travels 10meters in 5 seconds, he travels 200m in 100seconds.
Answer:
A. Repeat the experiment to be sure the results are valid.
Answer:
obviously 2 hours cuz 850/425
Explanation:
The correct answer to your question here is D
Answer:
(a) W=1.20×10⁴J
(b) U= -5.46×10⁴J
(c) Q= -4.26×10⁴J
Explanation:
Given that student does 1.20×10⁴J work
(a) W=1.20×10⁴J
Work done by student,so positive sign
During the process, his internal energy decreases by 5.46×10⁴J.
(b) U= -5.46×10⁴J.
As the Energy decreases therefore negative sign
For (c) Q
We know the formula
