Answer:
Explanation:
Given that
Beam current (i)=23.3µA
And the time to strike(t)=28s
Also, a fundamental charge e=1.602×10^-19C
Then, the charge quantity is given as,
q=it
Then, q=23.3×10^-6×28
q=6.524×10^-4C
Also, the number of electron N is given as
q=Ne
Therefore, N=q/e
So, N=6.524×10-4/1.602×10^-19
N=4.072×10^15
There are 4.072×10^15 electrons strike the tube screen every 28 s.

Answer:
Answer:
101325 + 10055.25h
//
h = 10.1 m
Explanation:
the pressure at sea level = 1 atm = 101325 Pa
density of sea water = 1025 kg/ m^(3)
pressure due to fluid height = pgh
Absolute pressure = 101325 + 1025*9.81*h
= 101325 + 10055.25h
where h= 0 at sea level at increases downwards
//
101325 = 1025* 9.81* h
h = 10.1 m
Explanation:
Answer:Both will continue traveling at the same speed because there is no friction.
Explanation: Gravitational force or pull is the force acting to attract all object in and around the Earth to the center of the Earth. The Earth's Gravitational force acts as a Bar magnet.
When objects are working outside the impact of the force of Gravity,it will not matter whether the objects are of the same size or wether one is heavier than the other,in this case both objects will move at the same speed as there is no impact of the Force of Gravity.
Answer:
5. The 2 features we need to harness the energy from tides are when tides come in and when tides come out.
6. Tidal energy is the most predictable type of renewable energy is because we know the exact locations of the sun and moon all year round.
