Why there will be a change in the sole of the shoes after using many days?

Answers

Answer:

See the explanation below

Explanation:

Due to the frictional force, this force acts in the opposite direction to the movement of the person's shoe. This force tends to wear the sole of any shoe. We must remember that the frictional force is defined as the product of the normal force by the coefficient of friction between surfaces.

For this case, it should be the coefficient of dynamic friction between the pavement and the material of the sole of the shoe

Explain the scientific meaning of the word random

Answers

Explanation:

In general the word random means by chance. The event that occurs unknowingly rather than according to plan is called at its randomness.

But in science, the word random relates with a type of event that is described by its probability distribution.

Also, random means the entropy of the system i.e. it is a thermodynamic quantity that represents the amount of energy in the system that is unavailable for doing work.

In what way does varying the length of a string of a violin change the vibration and how does this affect the sound that's produced?

Answers

The wavelength is the so-called "fundamental" wavelength, or the "first mode." Thus, the wavelength of the string's vibration is defined by the supports, and has nothing whatsoever to do with mass or elasticity.

Explanation:

When car tires are on hot pavement for too long, the pressure inside will ___________ and the volume within the tire will _____________. A) increase; decrease due to deflation B) decrease; remain unchanged C) increase; increase and possibly result in a blowout D) increase; remain unchanged as long as the temperature is constantly rising

Answers

When the car is driven at high speed for a long time on rough pavement,
the tires and the air inside them heat up.

That causes the air pressure inside the tires to increase, and the increased
pressure tries to make the tires bigger (they ARE made of rubber, after all).

Normally, the tires do expand a little. But if this goes on for too long, or
if there's a weak spot on the tire, a blowout is possible.
