What is the difference between current electricity and static electricity

Allisa [31]

Answer:

The most significant difference between the static and current electricity is that in static electricity the charges are at rest and they are accumulating on the surface of the insulator. Whereas in current electricity the electrons are moving inside the conductor.

A 10 kg box slides horizontally without friction at a speed of 1 m/s. At one point, a constant force is applied to the box in th

GrogVix [38]

Answer:

Fapp = 3 N

Explanation:

Applying the work-energy theorem, we know that the net work done on one object by an applied force, is equal to the change in the kinetic energy of the object.
This work is just the product of the applied force times the displacement, as follows:

$W_{net} = F_{app} * d (1)$

This must be equal to the change in kinetic energy:

$\Delta K = K_{f} - K_{i} = \frac{1}2}* m* (v_{f} ^{2} -v_{i} ^{2} ) (2)$

Equating (1) and (2), and replacing by the givens, we can solve for Fapp, as follows:

$F_{app} =(\frac{1}2}* m* (v_{f} ^{2} -v_{i} ^{2} ) ) / d = (5 kg* (2m/s)^{2} -1m/s^{2})/ 5 m = 3 N$

The magnitude of the applied force is 3 N.

In an insulated container, liquid water is mixed with ice. What can you conclude about the phases present in the container when

Ann [662]

Answer:

d. There is no way of knowing the phase composition without more information.

Explanation:

There is no way to ascertain the phases present in the container when equilibrium is established because we are not furnished with enough information.

The most important information needed to have a deeper understanding and provide solution is temperature.
Liquid water and ice can both exist at the same temperature.
So we cannot conclude based on the information at hand.
