The weight of a body above sea level varies inversely with the square of the distance from the center of Earth. If a woman weigh

s 131 pounds when she is at sea​ level, 3960 miles from the center of​ Earth, how much will she weigh when she is at the top of a​ mountain, 4.8 miles above sea​ level?

Answer:

89.16pounds

Explanation:

The equation that defines this problem is as follows

W=k/X^2

where

W=Weight

K= proportionality constant

X=distance from the center of Earth

first we must find the constant of proportionality, with the first part of the problem

k=WX^2=131x3960^2=2054289600pounds x miles^2

then we use the equation to calculate the woman's weight with the new distance

W=2054289600/(4800)^2=89.16pounds

An infnitely long metal cylinder rotates about its symmetry axis with an angular velocity omega. The cylinder is charged. The ch
Klio2033 [76]

Answer:

B = \frac{\mu_0 \rho r^2 \omega}{2}

Explanation:

Let the position of the point where magnetic field is to be determined is at distance "r" from the axis of cylinder

so here total charge lying in this region is

q = \rho(\pi r^2 L)

now magnetic field inside the cylinder is given as

B = \frac{\mu_0 N i}{L}

here current is given as

i = \frac{q\omega}{2\pi}

i = \frac{\rho (\pi r^2 L) \omega}{2\pi}

i = \frac{\rho r^2 L \omega}{2}

now magnetic field is given as

B = \frac{\mu_0 \rho r^2 L \omega}{2L}

B = \frac{\mu_0 \rho r^2 \omega}{2}
