A car accelerates from rest at an incredibly slow rate of 0.5 m/s/s.
How long does it take for the car to reach a final
velocity of 30 m/s?

60 seconds

Explanation:

Acceleration is the rate of change of velocity. For every second that passes, the velocity increases by an increment of 0.5. So after 60 seconds, the velocity of the car will be 30 m/s.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
