Explain why fluids travel faster near the center of pipes and tubes than at the edges

Answers

I think fluids travel faster near the center of pipes and tubes better than at the edges because they are able to travel much faster, and smoother in the center rather than the edges because the fluids have to turn, which could cause the rest of the incoming fluids to stop, which would make it much slower when traveling through the edges than through the center.

What effect does solar radiation have on climate when comparing the equator to polar- regions?

Answers

Answer:

The solar radiation is one of the main factors that shapes the climate all over the globe, so the climate differs with the less or more solar radiation it gets. The polar regions are cold, this is due to the fact that the solar radiation in here is very obscure, because the solar radiation falls at a very wide angle the heat is dispersed over larger area, thus the land gets very little warmth. The Equator, on the other hand, gets direct solar radiation, the sun light falls at a 90 degrees angle or close to it, so the radiation is more concentrated on a smaller area, thus the warming is bigger.

A polo player hits a ball with a mass of 0.42 kg with a force of 7.35 Newtons. How does the force the polo player's mallet exerted on the ball compare to the force the ball exerted on the mallet?

A.
The force of the on the mallet is less in magnitude and opposite in direction to the force the ball exerted on the mallet.

B.
The force of the mallet on the ball is greater in magnitude and opposite in direction to the force the ball exerted on the mallet.

C.
The force of the mallet on the ball is equal in magnitude and opposite in direction to the force the ball exerted on the mallet.

D.
The force of the mallet on the ball is equal in magnitude and in the same direction to the force the ball exerted on the mallet.

Answers

Due to the law of conservation of momentum, the force exerted on the mallet is equal and opposite to the force exerted on the ball, so the answer is C.

The answer is C. The force of the mallet on the ball is equal in magnitude and opposite in direction to the force the ball exerted on the mallet.

As an object falls to the ground, its potential energy is being converted to kinetic energy.True
False

Answers

Answer:

The statement is true

Explanation:

Energy Conversion

When an object starts to fall in free air, it speeds up as it falls. The force of gravity acting on the object causes energy to be transferred from its gravitational potential energy to its kinetic energy. We can safely say the height converts to speed and vice-versa. If no external forces act on the system, we can easily calculate heights and speeds by knowing the total mechanical energy (gravitational potential plus kinetic) is conserved.

Answer:

$\boxed{\text{The statement is true}}$
