Answer:
White dwarfs because you look at where the highest temperature is and where is the highest magnitude. Fun fact, the sun will become a white dwarf.

Answer:
Explanation:
1.3 g = 1.3 / 2 = .65 moles of hydrogen .
.65 moles = 6.02 x 10²³ x .65 molecules
Translational kinetic energy of one molecule = 1/2 mc² where c is rms speed = 1/2 x 2 x 1.67 x 10⁻²⁷ x ( 1600 )² = 42752 x 10⁻²⁵ J
Translational kinetic energy of .65 moles = 6.02 x 10²³ x .65 x 42752 x 10⁻²⁵ J
= 1673 J approx .
B ) Total thermal energy and total translational kinetic energy are same so
Thermal energy of gas = 1673 J
C ) Net content of thermal energy = 1673 + 500 - 2000 = 173 J
If c be the rms speed
1/2 x 2 x 1.67 x 10⁻²⁷ x .65 x 6.02 x 10²³ c² = 173
6.534 x 10⁻⁴ c² = 173
c² = 264769
c = 514.56 m /s
As we know that work done due a force F is given by formula
here F = applied force due to which work is done
d = displacement of object
now here we will have
W = 588 J
d = 1.4 m
now we can find force by above formula
So applied force by milkman is F = 420 N
