Answer:

the thickness of the glass divided by thickness of water is going to be 1.333 divided by 1.52, which is 0.877. So, the height of this glass, in order to have the same number of wavelengths as in water, the height of the glass will be 0.877 times the height of the water, and so it will be smaller.

(a) When immersed in the liquid, the solid displaces an amount of liquid weighing 64 N - 48 N = 16 N, and this is the same as the magnitude of the buoyant force/upthrust.

(b) Archimedes' principle says the solid has a volume equal to that of the displaced liquid. At a density of 0.8 g/cm³ = 0.0008 kg/cm³, a 16-N amount of this liquid has a volume of

(16 N) / g × (1/0.0008 cm³/kg) = 2040.82 cm³

(c) Density is mass per unit volume, so you get the solid's density by dividing its mass (weight/g) by the volume in (b):

((64 N) / g) / (2040.82 cm³) ≈ 0.0032 kg/cm³ ≈ 3.2 g/cm³

• Most of the galaxies in the universe are moving away from

WARRIOR [948]

The frequency of the light observed from the Earth is $4.945\cdot 10^{14}Hz$

Explanation:

First of all, we start by noticing that the galaxy is receding from Earth (moving away): this means that according to the Doppler effect, the frequency of the light as seen from the Earth must be shorter than the real frequency of the light emitted by the galaxy.

Furthermore, we can quantify the change in frequency of the light using the following equation:

$\frac{\Delta f}{f}=\frac{v}{c}$
