Answer: Reflection by clouds
Explanation:
Only some shortwave radiation from the sun reaches the Earth's surface because solar radiation is being reflected by thick clouds and thin clouds transmit the solar radiation.
About 31 % of solar radiation is reflected by clouds. The tiny water particle scatters 20-90 % of incoming sunlight giving them a bright white appearance.
Answer:
Explanation:
given,
mass of block = 3 kg
spring constant k = 500 N/m
kinetic friction coefficient µk = 0.6
speed of block = 5 m/s
F = µk N
F = 0.6 x 3 x 9.8
F = 17.64 N
using energy conservation
250 x² + 17.64 x - 37.5 = 0
on solving
x = 0.354 m
graph is attached below
Answer:
Your answer would be B. fall
Explanation:
This is because sliding would be continuous it just said a fragment of rock fell vertically. Hope this helps
If the length and linear density are constant, the frequency is directly proportional to the square root of the tension.
