Answer:
On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light. On the other end of the spectrum are gamma rays, with wavelengths billions of times smaller than those of visible light.
Explanation:
add me as brainliest if u the answer is helpful
The correct answer is letter D. candela. The unit for measuring the rate at which light energy is radiated from a source is the candela. L<span>umen is the unit for measuring the total amount of visible light emitted by a source. Lux is lumen per square meter. </span>
I believe the answer you are looking for is perception.
Answer:
Er = 108 [J]
Explanation:
To solve this problem we must understand that the total energy is 200 [J]. Of this energy 44 [J] are lost in sound and 48 [J] are lost in heat. In such a way that these energy values must be subtracted from the total of the kinetic energy.
200 - 44 - 48 = Er
Where:
Er = remaining energy [J]
Er = 108 [J]
Larry's average speed is
(total distance) / (total time).
Speed = (80 km) / (60 min) = 80 km/hr .
Larry's average velocity is
(distance between start- and end- points),
in the direction from the start-point to the end-point.
Velocity = (40 km east) / (60 min) = 40 km/hr east .
