A researcher must only measure one variable at a time, and using a scientific control group gives reliable baseline data to compare their results with. For example, a medical study will use two groups, giving one set of patients the real medicine and the other a placebo, in order to rule out the placebo effect.

Answer all these questions

Kazeer [188]

Answer:

mechanical waves,

the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.

If the amplitude increases the volume increases and vice versa.

The type of medium affects a sound wave as sound travels with the help of the vibration in particles.

The higher the frequency, the shorter the wavelength.

A box is pulled up a rough ramp that makes an angle of 22 degrees with the horizontal surface. The surface of the ramp is the x-

kifflom [539]

Magnitude of the force of tension: 139 N

Explanation:

The surface of the ramp here is assumed to be the positive x-direction.

To solve this problem and find the magnitude of the force of tension, we have to analyze only the situation along the x-direction, since the force of tension lie in this direction.

There are three forces acting along the x-direction:

The force of tension, $F_T$ , acting up along the plane
The force of friction, $F_f=14.8 N$ , acting down along the plane
The component of the weight in the x-direction, $F_{gx}$ , acting down along the plane
