The answer is visible light. Most of the solar radiation that reaches the Earth is made up of visible and infrared light. Only a small amount of ultraviolet radiation reaches the surface of the earth. Ordinary sunlight or solar radiation is broken into visible light (0.4 nm - 0.8 nm), ultraviolet light ( 0.4 nm) and the infrared radiation (0.8 nm). The visible light makes up almost half of the total radiation reaching the surface of the Earth.
Answer:
The force the ceiling exert on the hook is 321.67 N
Explanation:
Here we have the weights being 75 N and 125 N
The weight of the pulley = 80 N
Total weight hung from the ceiling = 75 + 125 + 80 = 280 N
Therefore since the forces acting on the ceiling tends to act downwards as they are the forces due to weights, we have
The force on the
T₁ - 125 = m₂a =
m₂ = 125/9.8 = 12.76 kg
Similarly T₂ - 75 = m₁a, m₁ = 7.65 kg
acceleration is given by
= 2.042 m/s²
Therefore
T₁ - 125 = m₂a = 12.76 × 2.042 = 26.04 N and
T₁ = 125 + 26.04 = 151.04 N
Similarly T₂ - 75 = m₁a = 7.65 × 2.042 = 15.63 N
T₂ = 15.63 + 75 = 90.63 N
Force on hook = Force exerted by ceiling on hook = T₁ + T₂ + Weight of pulley = 151.04 + 90.63 + 80 = 321.67 N
The units are not consistent - 1 m/s is not the same as 1 km/h.
First thing to do would be to convert from one unit of speed to the other, say km/h to m/s. There are 1000 meters (m) for every kilometer (km) and 3600 seconds (s) for every hour (h), so
So in fact 1 km/h is about 4 times slower than 1 m/s.
