Answer: 
Explanation:
The Compton Shift 
in wavelength when photons are scattered is given by the following equation:
(1)
Where:
is the wavelength of the scattered photon
is the wavelength of the incident photon
is a constant whose value is given by 
, being 
the Planck constant, 
the mass of the electron and 
the speed of light in vacuum.
the angle between incident phhoton and the scatered photon.
(2)
(3) This is the shift in wavelength
Answer:
f = 347.08 N
Explanation:
The frictional force exerted by the floor on the refrigerator is given as follows:
where,
f = frictional force = ?
μ = coefficient of static friction = 0.58
W = Weight of refrigerator = mg
m = mass of refrigerator = 61 kg
g = acceleration due to gravity = 9.81 m/s²
Therefore,
<u>f = 347.08 N</u>
Gravity
Explanation:
Johanna's table:
Circular motion Centripetal force
space station in orbit X
a child in a swing
a ball on a string
The type of centripetal force at work in a space station in orbit is the force of gravity.
The force of gravity is constantly pulling and attractive all objects and bodies to its center.
This force is directed towards the center of the orbit of the earth and it is a centripetal force
- Gravity attracts any object that has mass.
- The mass of the satellite and the earth keeps it in orbit and prevents it from moving out of orbit.
- The more the mass the more the gravitational attraction.

Answer:</h3>
539.56 Joules
<h3>
Explanation:</h3>
- Efficiency of a machine is the ratio of work output to work input expressed as a percentage.
- Efficiency = (work output/work input) × 100%
- Efficiency of a machine is not 100% because so energy is lost due to friction of the moving parts and also as heat.
In this case;
Efficiency = 94%
Work input = 574 Joules
Therefore, Assuming work output is x
94% = (x/574 J) × 100%
0.94 = (x/574 J)
<h3>x = 539.56 J</h3>
Thus, you get work of 539.56 J from the machine
