What do you mean by pressure of a liquid? Write its Sl unit.
1 answer:
Explanation:
Pressure of a liquid :
Liquids also exert pressure as that in case of solids. We can understand it as the fact that it is impossible to hammer a nail with liquid. That's why liquid exert pressure on its surface. The formula for the pressure in liquid is given by :
Where
= density of liquid
g = acceleration due to gravity
h = height
The SI init of pressure is Pascal and it is dented by Pa.

Answer:
4341.44763 kg/m³
Explanation:
= Actual density of cube = 1800 kg/m³
= Density change due to motion
v = Velocity of cube = 0.91c
c = Speed of light =
Relativistic density is given by
The cube's density as measured by an experimenter in the laboratory is 4341.44763 kg/m³
The energy the electron gives up passing between the electrodes is equal to the product between its charge and the potential difference between the electrodes:
where
e is the electron charge
is the potential difference
Plugging numbers into the equation, we find that the electron gives up is
where
e is the electron charge
Plugging numbers into the equation, we find that the electron gives up is
Answer:
Net electric field,
Explanation:
Given that,
Charge 1,
Charge 2,
distance, d = 3.2 cm = 0.032 m
Electric field due to charge 1 is given by :
Electric field due to charge 2 is given by :
The point charges have opposite charge. So, the net electric field is given by the sum of electric field due to both charges as :
So, the electric field strength at the midpoint between the two charges is 91406.24 N/C. Hence, this is the required solution.
