Since the kinetic energy is proportional to the square of the velocity, the doubling of the velocity has greater effect.
Doubling the base, but leaving the height unchanged, will double the area.
the velocity is decreased
They both have the same effect on the surface area of the pipe, but the radius has more effect on its volume/capacity.
Its energy is doubled.
Doubling the speed. This is because the (non-relativistic) kinetic energy is proportional to the square of the speed.
pressure will be halved
The volume increases by 8 times (23). doubling is 2, so its 2 to the power of 3. Leigh
It is define as twice the maximum symetrical short circuit current.
Several effects - for example, you get to your destination faster. You also have a greater risk of an accident.
there is no effect of mass on time period because mass and time period are inversely proportional
