Answer:
Work = 5941 J
Explanation:
As we know that work done is given by the equation
here we know that
also we have
now from above formula we have
This is the photoelectric effect, and it is best explained by the particle model of light.
<h3>What is the photoelectric effect?</h3>
The photoelectric effect refers to the emission of negatively charged particles and electromagnetic radiation that hits an object.
The photoelectric effect shows how electrons can be released from a given object when this material is absorbing electromagnetic radiation.
The photoelectric effect is a fundamental piece of evidence for understanding the nature of light particles.

Answer:
Explanation:
Using the formula for calculating range expressed as;
R = U√2H/g
U is the speed = 300m/s
H is the maximum height = 78.4m
g is the acceleration due to gravity = 9.8m/s²
Substitute into the fromula;
R = 300√2(78.4)/9.8
R = 300 √(16)
R = 300*4
R = 1200m
Hence the projectile travelled 1200m before hitting the ground

physical feature of a wave is related to the depth of the wave base is The circular orbital motion
B. The wave base is the depth, and the still water level is the horizontal level
Answer:
D
Explanation:
The color you see is the color the object reflectes. The rest of the color are absorbed by that object.
