A squirrel (mass 0.9 kg) is running across the road at a speed 4.0 m/s. What is thesquirrel's kinetic energy?

Answers

The kinetic energy of the squirrel with a mass of 0.9 Kg running with a speed of 4 m/s is  7.5 J.

What is kinetic energy?

Kinetic energy of an object is a form of energy generated by virtue of the motion of the object. Kinetic energy is dependent on the mass and velocity of the body.

When a body starts to move its potential energy starts to convert to kinetic energy and the kinetic energy will be maximum at the highest speed. When the object slow down and pause in a position it gains potential energy again.

The kinetic energy KE = 1/2 mv²

Given mass = 0.9 Kg

velocity = 4 m/s.

KE = 1/2 0.9 Kg × 4² m/s

     = 7.5 J

Therefore, the kinetic energy of the squirrel is 7.5 J.

The force applied when using a simple machine ??

Answers

Answer : I hope this helps !

The Effort Force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.

Final answer:

In physics, force is defined as a push or pull that can change the state of motion or shape of an object. When using a simple machine, the force applied is the input force or effort force. The amount of force required to operate a simple machine depends on its mechanical advantage.

Explanation:

In physics, force is defined as a push or pull that can change the state of motion or shape of an object. When using a simple machine, such as a lever or pulley, the force applied is the input force or effort force.

The amount of force required to operate a simple machine depends on its mechanical advantage. Mechanical advantage is the ratio of the output force to the input force.

For example, if you are using a lever with a mechanical advantage of 3, and you apply an input force of 10 Newtons, the output force will be 3 times greater, which is 30 Newtons.

5. Is it likely that light with frequencies higher than ultraviolet wasthe main cause of Tía Ana’s cataracts? Explain why or why not.

Answers

Answer: YES

Explanation:

If Tia Ana exposes her eyes to light ray in which it frequency is higher than ultraviolet ray, it may result to a gradual eyes issue such as cataracts as the radiation damages the cornea and the lens in front of the eyes.
