The period of a mechanical wave is 5 seconds. what is the frequency of the wave?

2 answers:

4 0

The frequency of a wave is just the reciprocal of the period.
For this one . . .

Frequency = 1/(period) = 1/(5 sec) = 0.2 per sec (0.2 Hz) .

Answer:

Frequency of the wave is 0.2 Hz.

Explanation:

It is given that, the period of a mechanical wave is 5 seconds. We have to find the frequency of the wave. Time period of a wave is defined as the time taken by the wave to complete one cycle and the number of oscillations or vibrations in a medium is called the frequency of the wave.

The relationship between the time period and the frequency of the wave is given by :

$f=\dfrac{1}{T}$ T = time period

$f=\dfrac{1}{5\ s}$

f = 0.2 Hertz

Hence, the correct option is (c) " 0.2 Hz ".

A person pushes a refrigerator across a horizontal floor. The mass of the refrigerator is 110 kg, the coefficient of static fric

Law Incorporation [45]

Answer:

Explanation:

mass of refrigerator, m = 110 kg

coefficient of static friction, μs = 0.85

coefficient of kinetic friction, μk = 0.59

(a) the minimum force required to just start the motion in refrigerator

F = μs x mg

F = 0.85 x 110 x 9.8

F = 916.3 N

(b) The force required to move the refrigerator with constant speed

F' = μk x mg

F' = 0.59 x 110 x 9.8

F' = 636.02 N

Net force = Applied force - friction force

F net = 950 - 636.02

F net = 313.98 N

a = F net / mass

a = 313.98 / 110

a = 2.85 m/s²

Beer, an alcoholic beverage, is a solution composed primarily of water with an ethanol content of about 7%. identify the solute

zloy xaker [14]

Hi, thank you for posting your question here at Brainly.

A mixture primarily consists of the solute and the solvent. The solvent constitutes the majority of the amount in the mixture. Since ethanol account for 7%, then water must be 93%, considering other inert materials to be negligible.

Thus, the solute is ethanol and the solvent is water.
