Several effects - for example, you get to your destination faster. You also have a greater risk of an accident.
Doubling the speed. This is because the (non-relativistic) kinetic energy is proportional to the square of the speed.
Speed (KE goes up by the square of the velocity).
the velocity is decreased
by doubling the amplitude.
pressure will be halved

Speed (KE goes up by the square of the velocity).
Doubling the mass will double the kinetic energy. Doubling the speed will increase kinetic energy by a factor 22 = 4.
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.
drag goes up 8times with the doubling of speed.
doubles
by doubling the amplitude.
The volume increases by 8 times (23). doubling is 2, so its 2 to the power of 3. Leigh
pressure will be halved
Speeding. Doubling the speed limit will turn a violation into a felony.
Doubling mass affects kinetic energy in that the greater the mass, the greater the kinetic energy. OK, but if you have a 10kg mass traveling at 2m/s and it bumps into and sticks to a 10g mass, the resultant speed would be 1m/s. The momentum stays the same. KE before is 10*2*2/2= 20, while the KE after is 20*1*1/2= 10. So it is not that the above answer is wrong, but rather, you question is not clear.
