Answer:
P = 800 Pa
Explanation:
The pressure of water at the bottom of the pot can be given by the following formula:
where,
P = Pressure at the bottom of the pot = ?
ρ = density = 1000 kg/m³
h = height of water = 8 cm = 0.08 m
Therefore,
<u>P = 800 Pa </u>
Answer:
Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container.
Explanation:
The pressure at any point in the fluid is equal in all directions.
Answer: The current required will be of 1.25 Ampere.
Explanation:
Voltage of one battery= 1.5 Volts
Voltage required by DVD player to operate, V = 6 × 1.5 = 9 Volts
Resistance offered by the device, R = 7.2 Ohms
V = IR (Ohm's law)
The current required will be of 1.25 Ampere.
Answer:
400 J
Explanation:
The efficiency of a machine is defined as
where
is the work output
is the work input
For this machine, we know the following
is the work in input
is the efficiency
Solving for the work output, we find
