When the force of air resistance on the skydiver
is equal to the skydiver's weight.
Answer:
The force exerted by the biceps is 143.8 kgf.
Explanation:
To calculate the force exerted by the biceps, we calculate the momentum in the elbow.
This momentum has to be zero so that her forearm remains motionless.
Being:
W: mass weight (6.15 kg)
d_W= distance to the mass weight (0.425 m)
A: weight of the forearm (2.25 kg)
d_A: distance to the center of mass of the forearm (0.425/2=0.2125 m)
H: force exerted by the biceps
d_H: distance to the point of connection of the biceps (0.0215 m)
The momemtum is:

The force exerted by the biceps is 143.8 kgf.
Answer:The energy in fossil fuels (coal, oil, gas)

Explanation:
Generally the moon's radial acceleration is mathematically represented as
Here
is the angular velocity which is mathematically represented as

substituting
for T(i.e the period of the moon ) we have
=>
From the question r(which is the radius of the orbit ) is evaluated as

substitute
for R and
H

=> 
So
Hello. The answer, though I don't know what options you need to be answered, is that there is less friction between the car tires and the ice, than when they are on the road. Causing the car to slide.
