Answer:

Options d.

Explanation:

As white light from the sun is passed through a prism, it is separated into colors - red, violet, yellow, blue, green, orange, and indigo.

Dispersion is the process of the separation of visible light into its different component colors. The light waves are refracted as they enter the prism.

So, option d. is correct.

How many grams of water would require 2200 joules of heat to raise it’s temperature from 34 degrees Celsius to 100 degrees celsi

Arada [10]

Answer:

Mass, m = 7.97 grams

Explanation:

We have,

Initial temperature was 34 degrees Celsius

Heat produced in it is 100 calories of heat

The specific heat capacity of water is 4.18 J/g °C

The heat produced due to change in temperature is given by :

$Q=mc(T_f-T_i)$

m is mass of water in grams

$m=\dfrac{Q}{c(T_f-T_i)}\\\\m=\dfrac{2200}{4.18\times (100-34)}\\\\m=7.97\ g$

So, 7.97 grams of water is required to produce heat of 2200 joules.
