When a gas is compressed, its particles are pushed closer together so it is more dense.
Answer:
Though no question is specified here but let analyzed experiences of each
Explanation:
1. Required a force to stop it (Law of inertial). Constant acceleration
2. will have reduced acceleration (deceleration)
3. Uniform acceleration may set in. it accelerate
4. maximized it speed since no friction affect it motion
5. accelerating. Vo=0 and V gradually increased
6. less or no friction opposes the motion
7. It experience reduce motion based on air friction
8. constant acceleration due to gravity
9. g can be a bit affected but still about equal
Explanation:
Equilibrium position in y direction:
W = Fb (Weight of the block is equal to buoyant force)
m*g = V*p*g
V under water = A*h
hence,
m = A*h*p
Using Newton 2nd Law

Hence, T time period
T = 2*pi*sqrt ( h / g )
Answer: • Visible Light, Radio Waves
• Radio - 305-m , at Arecibo, Puerto Rico
Visible Light - 10.4m Mirror, Canary Island
Explanation:
The spectral window is simply the range of frequencies that are correctly measured. It should be noted that the signals that are outside the spectral window are folded when they show up in spectrum.
The two spectral windows through which electromagnetic radiation easily reaches the surface of earth are the visible light and the radio waves.
