Answer:
The difference between heat and thermal energy is that thermal energy is not in the process of being transferred; it is not in transit, but remains as part of the internal energy of the system; heat, on the other hand, is energy in transit, i.e. energy in the process of being transferred from a hotter system.
Explanation:
Answer:
0.10 m
Explanation:
The magnetic flux through the plane is given by
where
B is the magnetic field intensity
A is the area of enclosed by the pipe
In this problem, we know
is the flux
B = 0.90 T is the magnetic field strength
Solving the equation for A, we find the area enclosed by the pipe
We know that the area is given by
where r is the radius. Solving for r, we find the radius:
And so the diameter is twice the radius:
I believe you're talking about displacement. It's a directional vector that depicts the movement of a point between two instances.
1.Momentum is conserved
3.Kinetic energy is conserved
6.Object's bounce apart
In perfectly elastic collision, the momentum and kinetic energy of teh colliding molecule is preserved because there is no loss in energy from the collision.
Explanation:
Ideally most collisions are inelastic meaning some energy is lost in the collision mostly as heat energy. This is why in inelastic collisions, the molecules will have a reduced momentum and kinetic energy. An example of an inelastic collision is a bouncing tennis ball on the tennis court. With every bounce, it loses some energy hence its height of bounce after every bounce reduces until the ball stops bouncing.

The pulley is really a wheel and axle with a rope or chain attached. A pulley makes work seem easier because it changes the direction of motion to work with gravity. Let's say you have to lift a heavy load, like a bale of hay, up to the second floor of a barn. You could tie a rope to the bale of hay, stand on the second floor, and pull it straight up. Or you could put a pulley at the second floor, stand at the first floor, and lift the bale of hay by pulling straight down. It would be the exact amount of work in either case, but the action of pulling down feels easier because you're working with the force of gravity.
A pulley really saves effort when you have more than one pulley working together. By looping a rope around two, three, or even four pulleys, you can really cut down on the effort needed to lift something. The trade-off? Well, as you increase the number of pulleys, you also increase the distance you have to pull the rope. In other words, if you use two pulleys, it takes half the effort to lift something, but you have to pull the rope twice as far. Three pulleys will result in one-third the effort — but the distance you have to pull the rope is tripled!
