The total gauge pressure at the bottom of the cylinder would
simply be the sum of the pressure exerted by water and pressure exerted by the
oil.
The formula for calculating pressure in a column is:
P = ρ g h
Where,
P = gauge pressure
ρ = density of the liquid
g = gravitational acceleration
h = height of liquid
Adding the two pressures will give the total:
P total = (ρ g h)_water + (ρ g h)_oil
P total = (1000 kg / m^3) (9.8 m / s^2) (0.30 m) + (900 kg /
m^3) (9.8 m / s^2) (0.4 - 0.30 m)
P total = 2940 Pa + 882 Pa
P total = 3,822 Pa
Answer:
The total gauge
pressure at the bottom is 3,822 Pa.
Answer:
Explanation:
When force applied to the end of the rod in perpendicular direction then net torque on the rod is given as
Now another force is applied at mid point of the rod at an angle of 30 degree with the rod
so new value of torque is given as
so we have
Answer: A transformer that increases the voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up transformer. As a step-down unit, this transformer converts high-voltage, low-current power into low-voltage, high-current power.

Answer:
The widely accepted theory for the origin and evolution of the universe is the Big Bang model, which states that the universe began as an incredibly hot, dense point roughly 13.7 billion years ago.
Answer:
9.17 x 10^-10 m
Explanation:
q = 1.6 x 10^-19 C
B = 4.55 x 10^4 T
m = 9.1 x 10^-31 kg
K = 22.5 eV = 22.5 x 1.6 x 10^-19 J = 3.6 x 10^-18 J
θ = 65.5°
Use the formula for the kinetic energy
Let r be the radius of circular path and v be th evelocity
By substituting the values
r = 3.52 x 10^-10 m
Use the formula for the speed
v = 2.82 x 10^6 m/s
The pitch of the helix = 
= 
= 9.17 x 10^-10 m
