Answer:
0.22 m
Explanation:
= Atmospheric pressure = 101325 Pa
= Pressure at the bottom = tex]2 P_{o}[/tex] = 2 (101325) = 202650 Pa
= height of the container = 7.59 m
= depth of the mercury
Pressure at the bottom = Atmospheric pressure + Pressure due to mercury + Pressure due to water
-- Multiply each side of the formula by 2
-- Then divide each side by t
-- Then subtract V(i) from each side.
Explanation:
A magnetic field can be created by running electricity through a wire. All magnetic fields are created by moving charged particles. Even the magnet on your fridge is magnetic because it contains electrons that are constantly moving around inside
Answer:
0.25 kg
Explanation:
Newton's second law states that:
where
F is the net force acting on an object
m is the object's mass
a is its acceleration
In this problem, we have:
is the force exerted on the object
m is the ball's mass
is its acceleration
Solving the formula for m, we can find the ball's mass:
