<h3>Explanation</h3>
The peak emission wavelength of an object depends on its absolute temperature.
,
where
is the wavelength in meters where the emission is the strongest.
is the temperature of the object in degrees Kelvins.
For the gas falling into the black hole,
.
Apply the formula:
.
The question mentioned that
is in the X-ray region of the electromagnetic spectrum. According to Encyclopedia Britannica, the wavelength of X-rays range from
to
, which indeed includes
.
higher frequency/shorter wavelength
OR
carries more energy than red light.
I have concluded that the formula for this equation would be F = ma, therefore the equation would look like this:
F = ma
F = 4,200n/ 2,000 kg
= 2.1
The rate of acceleration is 2.1, hopefully I this will be of assistance to you. :)

The amount of metal in a closed cylindrical can that is 10 cm high and 4 cm in diameter if the metal on the top and the bottom is 0.1 cm thick and the metal on the sides is 0.05 cm thick is 8.8 cm.
The formula for calculating the volume of a cylinder is given below.
V = πr^2 h
Get the differential of the volume as shown:
dV = V/ h dh + V / r dr
V/ h = πr^2
V/ h = 2 πr h
Now, the differential becomes
dV = πr^2dh + 2πrh dr
Given the following parameters i.e. diameter and height
dh = 0.1 + 0.1 = 0.2 cm
dr = 0.05 cm
h = 10 cm
d = 4 cm
r = 2cm
Substituting the values in the above equation, we get
dV = 3.14(2)^2(0.2) + 2(3.14)(2)(10)(0.05)
dV = 2.512 + 6.28
dV = 8.792 cm
dV = 8.8 cm
