Answer:

The wavelength of the wave is tripled this can be done by reducing the frequency of the wave by factor of three.

Explanation :

The relation between the wavelength & frequency of a wave is given by

C = ν λ

Where

C - it is the velocity of light in vacuum.

ν - frequency of the wave.

λ - wavelength of the wave.

So we find that wavelength of a wave varies inversely with the frequency of a wave i.e. ν ∝ 1/λ.

the weight of a piece of stone when fully immersed in water is 18N and it displaces 4N of water. what is the weight of the stone
goldfiish [28.3K]

Answer:

4N

Explanation:

Given parameters:

Weight of stone when immersed in water  = 18N

Weight of water displaced  = 4N

Unknown:

Weight of the stone in air  = ?

Solution:

To solve this problem, we employ the Archimedes' principles.

It states that the upward buoyant force on a body is equal to the weight of the fluid displaced.

The weight of the water displaced is equal to the weight of the body.

So, the weight of the stone in air  = 4N
