Answer:
The force is 
Explanation:
From the question we are told that
The mass of the bungee jumper is m = 80 kg
The spring constant is 
The extension of the rubber bungee cords is x = 50 m
Generally the weight of the jumper is

=> 
=> tex]W = 784 \ N [/tex]
Generally the returning force of the rubber bungee cords is mathematically represented as

=> 
=> 
The force to be applied by the bear is

=> 
=> 
The answer is: [D]: "force".

Answer:
2. +0.2 C
Explanation:
When the two spheres touch, the total charge will be redistributed such that the two spheres are at same potential:

The potential can be rewritten as ratio between the charge on the sphere (Q) and the capacitance of the sphere (C):

Since the two spheres are identical, they have same capacitance:

So we can write


And since the total charge is

And this charge will be redistributed equally on the two spheres (
), we have

<span> Balanced. If not so, then the car cannot move with uniform speed. The frictional force is balanced by the force exerted by the engine. </span>
The better predictor of increase in force of contraction, change in semg amplitude of spikes.
<h3>What is force?</h3>
A force in physics is an effect that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given that in the question the better predictor of increase in force of contraction, change in semg amplitude of spikes or change in semg frequency of spikes.
The better predictor of increase in force of contraction, change in semg amplitude of spikes.
