Answer:
3400 m
Explanation:
Both lightning and thunder happen at the same time but one is faster than the other. The distance traveled by a sound can be calculated from its speed such that;
speed = distance/time, hence, distance = speed x time.
<em>For a thunder with 340 m/s speed and 10 seconds away from lightning, the distance between the thunder and the lightning can be calculated as</em>;
distance = 340 m/s x 10 s = 3400 m
Answer:
P = 1447.51 Watts
Explanation:
Given that,
Mass of the person, m = 87.4 kg
Length of the hillside, l = 12 m
Inclination above horizontal, ![\theta=25^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D25%5E%7B%5Ccirc%7D)
Time, t = 3 s
Let h is the height of the hillside, it can be calculated using trigonometry.
![h=l\ sin(25)](https://tex.z-dn.net/?f=h%3Dl%5C%20sin%2825%29)
![h=12\times \ sin(25)](https://tex.z-dn.net/?f=h%3D12%5Ctimes%20%5C%20sin%2825%29)
h = 5.07 m
Let P is the minimum average power output. It is equal to the energy per unit time. Its formula is given by :
![P=\dfrac{E}{t}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BE%7D%7Bt%7D)
![P=\dfrac{mgh}{t}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7Bmgh%7D%7Bt%7D)
![P=\dfrac{87.4\times 9.8\times 5.07}{3}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B87.4%5Ctimes%209.8%5Ctimes%205.07%7D%7B3%7D)
P = 1447.51 Watts
So, the minimum average power output of the person is 1447.51 Watts. Hence, this is the required solution.
