Answer:
electeicity is caused by the movement of. from one atom to the next
Option (B)is correct.
Alternating electric and magnetic fields has electromagnetic radiation that travel in the form of a wave.
The varying or alternating electric field produces the varying magnetic field.This varying magnetic field in turn produces varying electric field . Thus these varying electric and magnetic fields travel in the form of electromagnetic waves. These electromagnetic waves travel with the velocity of light.These are transverse in nature.
Since the biker is moving at constant speed
so we will have
here we know that
time = 4 second
now we have
now at the top point it feels free fall
so it is
so height of the bike at the top is same as diameter
Yes it will hurt on falling from this height
The answer is:
Forces acting on the sled are paired with equal and opposite forces.
The explanation:
About to push you, this means that he doesn't push yet. If the sled is on level ground and no one is pushing it, then forces are equal and opposite.
The gravity force pulls down and the ground pushes up.
This is Newton's third law:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.
We can also see Newton’s third law at work by taking a look at how people move about. Consider a swimmer pushing off from the side of a pool.
Answer:
Kinetic energy
Explanation:
Kinetic energy is a function of velocity. Since the rider is moving at a certain speed, he's demonstrating kinetic energy. It can't be potential energy because potential energy encompass mgh
