When anyone pass the puppy then it will block the visible light that incident upon it
So here we are blocking the visible part of light by passing the puppy which means we have to design a sensor that will sense the visible light.
So here the electromagnetic part of the sensor is capable to detect this change only
so here correct answer must be
<u><em>B. Visible Light</em></u>
The answer is A. Weathering,erosion, and then transportation
Let d = distance that the fugitive travels to get on the train.
Let t = the time to travel the distance d.
The fugitive starts from rest accelerates at a = 3.8 m/s².
Therefore
(1/2)*(3.8 m/s²)*(t s)² = (d m)
1.9 t² = d (1)
The train travels at constant speed 5.0 m/s.
Therefore
(5.0 m/s)*(t s) = d
5t = d (2)
If the fugitive successfully boards the train, then equate (1) and (2).
1.9t² = 5t
t = 0 or t = 2.6316 s
Ignore t = 0, so t = 2.6316 s.
The speed of the fugitive after 2.6316 s, is
v = (3.8 m/s²)*(2.6316 s) = 10 s
This speed exceeds the maximum speed of the fugitive, therefore the fugitive fails to get on the train.
Answer: The fugitive fails to get on the train.

Answer:Yes
Explanation:
Given
mass
mass
Force of magnitude =17 N
coefficient of static friction
Lower block is glued to floor
Force cos component will try to move the upper block while sin component try to lower the Normal reaction
Normal reaction
and friction force
And force cos component =
As force cos component is more than the friction force therefore it slips w.r.t to lower block
