Answer: Period T = 4.44secs
Explanation: see attachment
yes because your mass doesn't change but your weight can
ex- if you travel to Saturn your weight would change but your mass would stay the same
Answer:
Se the explanation below
Explanation:
We do not feel these forces of these bodies, because they are very small compared to the force of Earth's attraction. Although its mass is greater than that of a human being, its mass is not compared to the Earth's mass. In order to understand this problem we will use numerical data and the universal gravitation formula, to give validity to the explanation.
<u>Force exerted by the Earth on a human being</u>
<u />

Where:
G = universal gravitation constant = 6.673*10^-11 [N*m^2/kg^2]
m1 = mass of the person = 80 [kg]
m2 = mass of the earth 5.97*10^24[kg]
r = distance from the center of the earth to the surface or earth radius = 6371 *10^3 [m]
<u />
Now replacing we have
![F = 6.673*10^{-11} *\frac{80*5.97*10^{24}}{(6371*10^{3})^{2} } \\F = 785[N]](https://tex.z-dn.net/?f=F%20%3D%206.673%2A10%5E%7B-11%7D%20%2A%5Cfrac%7B80%2A5.97%2A10%5E%7B24%7D%7D%7B%286371%2A10%5E%7B3%7D%29%5E%7B2%7D%20%20%7D%20%5C%5CF%20%3D%20785%5BN%5D)
<u>Force exerted by a building on a human being</u>
<u />
Where:
G = universal gravitation constant = 6.673*10^-11 [N*m^2/kg^2]
m1 = mass of the person = 80 [kg]
m2 = mass of the earth 300000 [ton] = 300 *10^6[kg]
r = distance from the building to the person = 2[m]
![F = 6.673*10^{-11}*\frac{80*300*10^6}{2^{2} } \\F= 0.4 [N]](https://tex.z-dn.net/?f=F%20%3D%206.673%2A10%5E%7B-11%7D%2A%5Cfrac%7B80%2A300%2A10%5E6%7D%7B2%5E%7B2%7D%20%7D%20%20%5C%5CF%3D%200.4%20%5BN%5D)
As we can see the force exerted by the Earth is 2000 times greater than that exerted by a building with the proposed data.
Answer:
377 m
Explanation:
number of turns, N = 65
θ = 36°
B1 = 200 micro Tesla
B2 = 600 micro tesla
t = 0.4 s
induced emf, e = 80 mV
Let a be the side of the square coil.



a = 1.45 m
Total length of the wire, L = N x 4a = 65 x 4 x 1.45 = 377 m
Thus, the length of the wire is 377 m.
