Explain the relationship between energy and the potential to do work

Physics

Alenkinab [10]3 years ago

Potential energy is the energy possessed by a body by virtue of its position or configuration . And energy is the capacity of doing work since power is work divided by time therefore change in potential energy divided by time is equal to the power of the object.

S_A_V [24]
The correct answer is decreases

The further away you are the weaker it would be. That's why at one point you stop being in the field and ti doesn't pull you towards it anymore. Proportionally, if you move towards the Earth then it increases.

The drift velocity should be in the same direction as the applied force. <br> a. true <br> b. false
Marina CMI [18]

It is a false statement i.e. drift velocity is not same in the direction as the applied force.

Drift velocity of a  current-carrying conductor can be explained as, the charges i.e. electrons do not  flow in the same direction of current. In other word, in most cases the movement of the electrons is almost random, with a small net velocity. So that , the drift velocity, in the direction opposite to the electric field.

Drift velocity v_{d} is inversely proportional to the number of electron per unit volume of the conductor e. Therefore, the formulation can be given as ,

v_{d} = σ E/ne

The above equation shows the drift velocity in a current carrying conductor  

where, v_{d} is drift velocity , σ is the conductivity, E is electric force and n is number of electrons per unit volume of the conductor e.

Hence here we can say that, the drift velocity is not in the same direction as the applied force.

Name the missing force... Normal <br>   Spring <br>   Tension <br>   Air Resistance
Kay [80]

the missing force is spring force.

The object is hanging from the spring and the spring is stretched by some distance from its equilibrium position.  due to this stretch in the spring , a spring force starts acting on the object trying to regain its equilibrium position.

the spring force is given as

F = kx

where F = spring force ,k = spring constant , x = stretch in the spring.

the spring force balances the weight of the object in down direction and hence keeps the block from falling down.
