There are longitudinal and transverse. Both types of mechanical waves require a medium, transport energy, and have defined wavelengths, frequencies, and speeds.
Differences are that transverse waves oscillate along a direction perpendicular to the direction of travel (like shaking a rope up and down). Longitudinal waves like oscillations along a spring and sound waves, oscillate back and forth along the direction of travel.
B. Frequency remains unchanged because the energy in a photon is E=hf. So if the frequency changes so does the energy and that doesn't happen to EM waves entering a medium by the conservation of energy
Answer:
In Celsius:
Explanation:
The formula we are going to use is:
Where:
ε is the emissivity
σ is the Stefan constant
is the final temperature of surrounding surfaces
is the required temperature
is the are of surrounding surface
Calculating The area:
σ= 
ε =0.95
=55+273
=328 K
=100 W
In Celsius:
Force in Newtons =
(1200)•(the rate of acceleration you want)
It depends on how fast you want to accelerate.
Inertia refers to the tendency of a body to resist changes.
<h3>Inertia</h3>
It is the property of a body to resist change.
A moving body will continue moving until a force acts on it. Unless the acting force is big enough to overcome the inertia of the body, the body will continue moving.
Also, a body at rest will continue resting unless a force big enough to overcome the inertia force is used to displace it.
