Answer:
The Difference between Radio Waves and Infrared Light. According to NASA, radio waves have a longer wavelength than infrared light, in the electromagnetic spectrum. Radio waves are able to reach the earth’s surface, unlike most infrared light.
Explanation:
I hope this helps.
Shiddd ion even know but can you like my comment?
The amount of heat transferred to water is equal to the amount of heat that is lost by the piece of iron dropped to it. To solve for the quantity of the heat in either direction, we use the equation,
H = mcpdT
where H is heat, m is mass, cp is the specific gravity, and dT is the change in temperature. Substituting,
H = (200g)(0.444 J/g°C)(100°C - 22°C)
H = 6926.4 J
Thus, the heat lost by the piece of iron is approximately 6926.4 J.
Answer:
-78.4 cm
Explanation:
We can solve the problem by using the lens equation:
where
p is the distance of the object from the lens
q is the distance of the image from the lens
f is the focal length
Here we have
p = 80.0 cm
q = -39.6 cm (negative, because the image is on the same side as the object , so it is a virtual image)
Substituting, we find f:
The magnitude of the angular momentum of the rod immediately after the collision is given as (pf + pi) * d. (Option A).
<h3>
What is Angular Momentum?</h3>
Angular Momentum may be defined or described as the vector quantity of the rotation of a body, which is arrived at by multiplying its moment of inertia by its angular velocity.
The formula for Angular Momentum is given as:
L = <em>mvr; Where
L = Angular Momentum</em>
<em>m = mass</em>
<em>v = velocity; and </em>
<em>r = radius.</em>
