Explain how inertia and the shape of a loop counteract the force of gravity to keep riders from falling out when a roller coaster goes through a loop traveling upside down

Answers

Answer 1

Answer: When a roller coaster car goes through a loop, inertia keeps it from being pulled down by gravity. Inertia is the tendency of an object to resist a change in its motion, meaning that an object (the roller coaster car) which is already moving will resist forces that try to stop it. It will continue to try to move in a constant speed in a constant direction, even if other forces are slowing it down. The shape of the loop in a roller coaster is made so that the car can travel up it without losing its momentum. This is why a roller coaster car needs to be travelling at high speeds to go through a loop. If it weren't travelling quickly enough, the forces of gravity would pull it down before it could make it all the way through the loop.

Me finding out bananas are curved because they grow towards the sun what do you think about this ?

Answers

Answer:

Bananas go through a unique process known as negative geotropism. Instead of continuing to grow towards the ground, they start to turn towards the sun. The fruit grows against gravity, giving the banana its familiar curved shape.

Answer:

this cannot be true, because why would both sides curve toward the sun?

Which improves air circulation in forced air heating? A, radiation b, conduction, c, convection

Answers

Answer:

Convection

Explanation:

As we know that in convection mode of heat transfer the medium molecules is transferred from one part to other part along with the thermal energy stored with them.

Here when heat is given to the medium then due to temperature gradient density of medium will change and this will lead to a movement of medium particles from higher density to lower density region.

This is known as convection mode of heat transfer and this mode of heat transfer can be increased by forced convection of medium particles.

So here air circulation in forced heating is an example of CONVECTION

The answer for "Which improves air circulation in forced air heating?" is C. Convection
