Can someone please help me with this question?

Answers

Answer 1

Answer: The answer is B because, the farther the goes the speed starts to decrease and stops it depends on the frequency of the wave.

How many electrons can fit in the fourth energy level

Answers

Hello User,

Approximately 32 electrons can be fit in the fourth energy level.

Solution:
2+4+6+10+10=32

The answer is 2 electrons because 2 + 6 + 10 + 14 = 32 electrons.

What factors affect the speed of a wave?

Answers

Speed of wave depends mainly on four factors. These factors are wavelength, frequency, medium and temperature.

We know from laws of refraction, when a wave travels from rarer to denser medium, the speed of wave slows down. And when it travels from denser to rarer, it speeds up.

The relation of speed of wave with its wavelength and frequency is given by the following:

$v = \lambda * f$

The speed of a wave in a particular medium remains constant. A higher frequency wave has shorter wavelength.

The speed of a wave also varies with temperature in a given medium. temperature affects the density of the medium and vibrations of the medium particles. Higher the temperature, higher is the speed of wave.

The factors that affect the speed of a wave are wavelength and medium. The correct option is B.

Wavelength and the characteristics of the medium a wave travels through are the two key parameters that affect a wave's speed.

Wavelength is the separation between successive wavepoints, and medium is the substance or material through which the wave is travelling, such as air, water, or solids.

The speed of the wave typically decreases as the wavelength rises. Additionally, the densities, compositions, and properties of various media can vary, which has an impact on how quickly a wave can go through them.

For instance, sound waves move through the air more quickly than they do through water. In disciplines like physics, acoustics, and communications, having an understanding of these elements is essential.

Thus, the correct option is B.

What is the velocity of a car that travels 100 meters north in for seconds

Answers

The velocity is 25 because you just divide 100/4

The equation for velocity is distance/time.. So if it goes 100m in 4 seconds.. It's 100/4 which equals 25 mls north. (Velocity includes the direction in the answer)
