Answer:
<h3>5 meter / sec.</h3><h3 />
Explanation:
speed = distance / time
= 15 meters / 3 seconds
= 5 meter / sec.
Answer:
please find the answer in the attached image, divided in 2 parts.
This means that there is same current flow in both the circuit, or the circuit one has twice the power of circuit two.
According to ohm's law, the resistance is given as
I=V/R
Since the circuit one has twice the voltage, and resistance
I1=I2
Answer:
Mass of body A, m
1
=m
Mass of body B, m
2
=m
Height h

=h
Height h
2
=2h
Acceleration due to gravity, g
1
=g
Acceleration due to gravity, g

=g
PotentialEnergy(P.E

)
PotentialEnergy(P.E

)
=?
P.E=mgh
⇒P.Eαh
(∴ 'm' and 'g' are constants)
⇒
P.E

Therefore, the ratio of potential energy is of the two bodies is 1 : 2.
