Cell phones use RF waves from nearby cell towers. RF waves fall in between FM radio waves and microwaves
natural motion is the motion that requires no force
Stephen`s Law:
P = (Sigma) · A · e · T^4
P in = P out
e = 1 for blacktop;
1150 W = (Sigma) · T^4
(Sigma) = 5.669 · 10 ^(-8) W/m²K^4
T^4 = 1150 : ( 5.669 · 10^(-8) )
T^4 = 202.875 · 10^8
![T = \sqrt[4]{202.857 * 10 ^{8} }](https://tex.z-dn.net/?f=T%20%3D%20%20%5Csqrt%5B4%5D%7B202.857%20%2A%2010%20%5E%7B8%7D%20%7D%20)
T = 3.774 · 10² =
377.4 KAnswer: Equilibrium temperature is 377.4 K.
Partial. a penumbral lunar eclipse is when the moon passes through the earths penumbra
24. 02 N force of friction acting on the box.
<h3 /><h3>What is force?</h3>
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Force = mass. acceleration
Force = (2.2).(3.2)
Force = 7.04 N
Total force applied is 31.06 N
Frictional force = 31.06 - 7.04
Frictional force = 24. 02 N
24. 02 N force of friction acting on the box.
