Drag is passive, therefore it does not act on gravity. Drag is a mechanical resistance to motion. If the motion in question was induced by gravity drag it can impede that motion, but has no effect on the gravity. 

hope this helps!

Answer:

Drag is a force of resistance that acts in fluid motion. When there is relative motion with respect to a fluid, a drag force acts in the opposite direction to the motion. Drag depends on viscosity, compressibility of the fluid and mass of the object.

When the sum of drag force and buoyant force are equal to the downward force of gravity, the object falls with a constant velocity known as terminal velocity.

A student connects four AA batteries (1.5 V each) in series to light up a light bulb. The circuit has a resistance of 50 Ω. How
VLD [36.1K]

Answer:

0.3

Explanation:

V = I R

1.5= I (50)

I = 1.5/50

I = 0.3 J

Therefore, 0.3joule current flows through the circuit.

If your brakes fail, look for something to rub against, try to pick something that will not give way.True or False?
Yanka [14]

Answer:

False

Explanation:

False

If brakes fail then we should not run against any object or wall to slow down the speed instead we should use friction forces slow down the car and shift gear to neutral to cease any acceleration.

By driving zig-zag motion friction force on the tires may stop the car after some distance.

Do not try to shut off the engine as it will lock the steering mechanism any prove fatal.
