Kinetic energy is the energy of motion. The mass and velocity of an object determines its kinetic energy
Answer:
the answer is A. air is cooler than the ground.
Explanation:
Answer:
Explanation:
For resistance the formula is as follows
R = ρ L/S
where L is length of the wire , ρ is a constant for a specific material called specific resistance and S is cross sectional area .
For 0.6 m wire , putting the values
.13 = ρ x 0.6 / S
For unknown wire
R = ρ x 187 / S
Dividing the two equations
R / .13 = 187 / .6
R = (.13 x 187) / .6
= 40.5 ohms .
Answer:
100
Explanation:
= Resistivity of axon
r = Radius of axon
t = Thickness of the membrane
= Resistivity of the axoplasm
Speed of pulse is given by
So, radius is given by
If radius is increased by a factor of 10 new radius will be
So, The radius will increase by a factor of 100.
The air inside the pipes of a wind instrument vibrates. ... The result is longitudinal standing waves in the air column inside the pipe. The ends, whether open or closed, create nodes or antinodes in these standing waves.
