Answer:
1.5
Explanation:
Data obtained from the question include:
C (critical angle) = 41.8°
n (refractive index od benzene) =?
Using the formula n = 1/sineC, the refractive index of benzene can be achieved as shown below:
n = 1/sineC
n = 1/sine 41.8°
n = 1.5
Therefore, the refractive index of benzene is 1.5

The power of the light bulb is given by:
where
V is the voltage of the bulb
I is the current through the bulb
In this problem,
V = 120 V
I = 0.75 A
Substituting into the equation,
Answer:

Ionising radiation (ionizing radiation) is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them. Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds (usually greater than 1% of the speed of light), and electromagnetic waves on the high-energy end of the electromagnetic spectrum.
