Answer:

The coefficient of friction does not change.

Explanation:

The reason for this is that the coefficient friction depends only on one variable, which is the nature of the surfaces in contact. Therefore, weight has no effect whatsoever on the coefficient of friction. hence, No change occurs in the coefficient of friction if the weight is changed.

Answer:

Usually the coefficient of friction remains unchanged

Explanation:

The coefficient of friction should in the majority of cases, remain constant no matter what your normal force is. When you apply a greater normal force, the frictional force increases, and your coefficient of friction stays the same. Here's another way to think about it: because the force of friction is equal to the normal force times the coefficient of friction, friction is increased when normal force is increased.

Plus, the coefficient of friction is a property of the materials being "rubbed", and this property usually does not depend on the normal force.

VELOCITY, SPEED, DISTANCE ETC..

vaieri [72.5K]

Answer:

Explanation:

Speed = distance / time

Velocity = displacement / time

So ,

Speed = 50 km / 0.5 hr = 100 km/h

Velocity = 40 km / 0.5hr = 80 km/h

Waves in the ocean are _____ traveling along the water

Mice21 [21]

The answer is energy.

Waves in the ocean are energy travelling along water.

Waves do not transport mass, they transport energy, this is the ability to perform work or exert force and distant points.

Although water seems to be travelling along with the wave, the molecules of water only move up and down; they do not travel along with the wave.

Which type of multiplexing is defined by wavelength instead of frequency? a. wdm b. cwdm c. dwdm d. fdm?

Rina8888 [55]

<span>Multiplexing is the process of combining numerous signal of data or sound on to a single carrier like an optical fiber by using different wavelengths. The type of multiplexing that is defined by wavelength instead of frequency is CWDM which is also known as Coarse Wavelength Division Multiplexing.</span>
