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:
the ability to do work.

in other words "the potential for causing changes" or "energy is the cause of any change" or "a work that a certain force *eg: gravitational* can do.

Answer:
f' =1064.1025 Hz
Explanation:
We know that from doppler's effect

f'= observed frequency
f= actual frequency =1000 Hz
v= velocity of sound waves = 332 m/s
v_o= velocity of observer =0
v_s= velocity of source. ( let velocity of car be 20 m/s)
therefore,

f' =1064.1025 Hz
Answer: I’m like 99% sure that’s the Grand Canyon
Explanation:it looks like it lol
Answer:
- The magnitude of the resulting force is 67 lbf.
Explanation:
Taking the east as the positive x direction, and the north as the positive y direction.
The first force points west, this is, in the direction of
, so, is


For the second force, knowing the magnitude and directions relative to the x axis, we can find Cartesian representation of the vectors using the formula

where
is the magnitude of the vector and θ the angle with the positive x direction.
So, the second force is


The net force will be :




To obtain the magnitude, we can use the Pythagorean Theorem



And this is the magnitude we are looking for.
