What is the basic unit that represents quantum nature of electricity?
OLga [1]
The basic unit that represents the quantum nature of electricity is the charge of the electron, represented with the symbols e, which corresponds to
|e|=1.6 \cdot 10^{-19}C

The quantum nature of electricity was demonstrated for the first time by Millikan, in its oil drop experiment. In this experiment, Millikan put charged oil drops between two metallic plates, applying a potential difference across them, such that the electrical force acting on the drops was in balance with their weight. Knowing the intensity of the electric field and the mass of the drops, he was able to determine the charge of the oil drops, and he found that this charge was always an integer multiple of a certain value, exactly e.

A 100kg cannon at rest contains a 10kgcannonball. when fired,
slega [8]

Answer:

9 m/s

Explanation:

mass of cannon, M = 100 kg

mass of cannon ball, m = 10 kg

velocity of cannon ball, v = 90 m/s

Let the recoil velocity of cannon is V.

Us ethe conservation of linear momentum, as no external force is acting on the system, so the linear momentum of the system is conserved.

Momentum before the firing = momentum after the firing

M x 0 + m x 0 = M x V + m x v

0 = 100 x V + 10 x 90

V = - 9 m/s

Thus, the recoil velocity of cannon is 9 m/s.

If the clot breaks free and only experiences a force due to the blood pressure, what is the relationship between the pressure on
Bingel [31]

Answer:

The pressure on each side of the clot is same.

Explanation:

The clot is moving with a constant velocity which implies that the total force on the clot is zero.

The force F is given by the formula.

F=ΔPA

where ΔP is the difference in pressure and A is the area.

Since the force is same on either side, therefore,

ΔPA=0

Also, the area is same on both side of the clot.

Therefore the difference in the pressure of both side is zero which implies that the pressure on both sides are equal.
