What is the speed of a swimmer if she covers 100m in 60 seconds?

Answers

Answer 1

Answer: To calculate the speed of a swimmer, you can use the formula:

Speed = Distance / Time

In this case, the distance covered is 100 meters, and the time taken is 60 seconds.

Speed = 100 meters / 60 seconds = 1.67 meters per second

So, the speed of the swimmer is approximately 1.67 meters per second.

Gymnasts often practice on foam floors, which increase the collision time when a gymnast falls. What effect does this have on collisions

The effect of the gymnast on the collision will increase. An elastic collision is when two bodies collide and separates after collision conserving the total kinetic energy before and after collision.

Answer:

it increces the time of the fall

Moons orbit planets and planets orbit theSun. Is Kepler’s constant the same for both
circumstances?

Answers

What Kepler's constant ? ? ! ?

The only constant in Kepler's laws is in the third one, where it says something to the
effect that (square of a body's period) / (cube of its distance from the central body)
is a constant.

That means it's a constant for multiple little ones orbiting the same central body.
But it's not the same constant for other central bodies.

It's one constant for the planets, asteroids, and comets orbiting the sun.

It's a different constant for the moon, TV satellites, weather satellites,
and military satellites orbiting the Earth.

Walking converts what type of energy into mechanical energy?

Answers

The answer is chemical energy.

In our body, our chemical energy comes in the form of glucose. It is glucose that is turned into mechanical energy in our body. When we move, our muscles act as a transducer. As muscles contract, they convert the glucose in our body into mechanical energy. The mechanical energy in our muscles is also called muscular energy.

The correct answer is chemical energy. Walking converts into a chemical energy which is a type of mechanical energy. Chemical energy is the energy stored in the chemical compound bonds and mostly released by the chemical reaction which will produce heat.
