Answer:
W = 1562.5 J
Explanation:
Path 1:
W₁ = F₁*d₁ = 385 N * 2.5 m = 962.5 J
Path 2:
W₂ = F₂*d₂ = 130 N * 10 m = 1300 J
Path 3:
W₃ = F₃*d₃ = (-350 N) * 2 m = - 700 J (opposite to the motion)
We get
W = W₁ + W₂ + W₃ = 962.5 J + 1300 J + (- 700 J) = 1562.5 J

Answer:
The infrared photon does not have greater energy as compare to visible rays so infrared rays pass through but due to greater energy than the gap visible rays could not hence silicon is transparent to infrared rays but silicon is opaque to visible rays .
Answer:
People might think that boiling an egg is nota chemical change. They might think this because the egg still looks really similar.
Explanation:
Since the train is moving at constant speed and direction, the velocity of the train is constant. According to Newton's First Law of Motion, when an object is moving at constant speed in a straight line(aka constant velocity), the resultant force experienced by the train is 0N. Since you're on the train, the resultant force experienced by you is 0N, thus, you do not have to exert a force to remain balanced.
