Suppose a 96.10 kg hiker has ascended to a height of 1841 m above sea level in the process of climbing Mt. Washington. By what p
lbvjy [14]

Answer:

0.029%

Explanation:

Weight on the surface is given by,

F_W = mg = (96.1Kg)(9.8m/s^2)=941.78N

The acceleration due to gravity at given height is,

g_h=\frac{gR^2}{R+h^2}

The weight in another height is equal to

F_h=mg_h

F_h= m*\frac{gR^2}{R+h^2}

F_h = \frac{F_WR^2}{(R+h)^2}

F_h=\frac{(941.78)(6.371*10^6)}{(6.371*10^6+1841)}

F_h = 941.50N

The change of the Weight is,

\frac{F-F_h}{F}*100=\frac{941.78-941.50}{941.78}*100=0.029\%

Can someone please explain how to solve 13?
frozen [14]

Hello!

Everything you've done so far seems to be correct. However, you need to get rid of the sin. To do this, use ssin^{-1}.

This is known as the inverse of sin, which is where you go from a fraction to the actual angle itself.

When you run sin^{-1}(1/5) through a calculator, you get about 11.537 degrees, or θ = 11.537.

To verify this, all you need to do is run sin (11.537), and the calculator returns 0.2, which is what we're looking for.

Hope this helps!

How to determine the center of gravity of a lamina​
goldenfox [79]
Take a lamina with three holes near the periphery of the lamina, now suspend the lamina through them, one by one. Draw a line of equilibrium for each suspension point. The point of intersection of these three lines would be the centre of gravity.
