A beta particle followed by another beta particle. Consider it beta positive decay in which a proton decays to form a neutron,positron and electron neutrino.
Answer:
Pressure, P = 3724 Pa
Explanation:
Given that,
Depth of water, 
Depth of oil, 
The density of water, 
The densinty of oil, 
We need to find the gauge pressure at the bottom of the cylinder. So, total pressure is equal to :
So, the gauge pressure at the bottom of the cylinder is 3724 Pa.
Answer:
1.73 seconds
Explanation:
The velocity the ball first hits the ground with is:
v² = v₀² + 2aΔx
v² = (0 m/s)² + 2 (-10 m/s²) (-20 m)
v = -20 m/s
The velocity it rebounds with is 3/4 of that in the opposite direction, or 15 m/s.
The time it takes to return to the ground is:
Δx = v₀ t + ½ at²
0 = (15 m/s) t + ½ (-10 m/s²) t²
0 = t (15 − 5t²)
t = √3
t ≈ 1.73 seconds
When a match stick is struck, some of the chemical energy is transformed into heat and light and the rest is converted into matter. A match stick has a lot of chemical energy stored in it. When its struck, It start burning. The chemical energy stored in it is transformed into heat energy and light energy. The rest of it turn into ashes and reaction gases.
