We know for newton's 2nd law of motion that the force on an object is equal to the mass of the object times the acceleration of

Dmitrij [34]

   Force = (mass) x (acceleration)

   5 N = (9 kg) x (acceleration)

Divide each side
by 9 kg : 5 N / 9 kg = acceleration

   Acceleration = (5/9) kg-meter/sec²-kg

   = 0.555... m/s²   .

Raindrops hitting the side windows of a car in motion often leave diagonal streaks even if there is no wind. Why? Is the explana

labwork [276]

Answer:

because of the raindrop velocity relative of the car has a vertical and horizontal component

Explanation:

The car moves in a <em>horizontal direction </em>relative to the ground. The raindrops fall in the <em>vertical direction</em> relative to the ground.
Their velocity relative to the moving car has both vertical and horizontal components and this is the reason for the diagonal streaks on the side window.
The diagonal streaks on the windshield arise from a different reason.
The drops are pushed off to one side of the windshield because of air resistance.

A cube 6.0 cm on each side is made of a metal alloy. After you drill a cylindrical hole 2.0 cm in diameter all the way through a

Crank

To solve this problem it is necessary to apply the concepts related to Newton's second law, the definition of density and the geometric relationships that allow us to find the volume of the figures presented.

For the particular case of the Cube with equal sides its volume is determined by

$V_c = l^3$
