Answer: The average force is 3934.71N
Explanation: Please see the attachments below
Get the linear acceleration
of center of sphere denoting it as y <span>
then the vertical gravitation would be x
To look for the angle of inclination which is b we
do the following steps:
90 - b = a
so cosine(a)= x/y
cosine(a)= (.24g)/g
a = 76 degrees (by using calculator or trig
table)
then b would be = 14 degrees </span>
Chemical energy in your muscles, divided between kinetic energy and frictional losses .
Well, you can pretty much see it with this formula :
I = V/R
If the resistance (R) is increased, the amount of I will be increased.
so the answer would be : A. The current decreases
