Answer:

distance/ kinetic

Explanation:

According to the work energy theorem, the work done by all forces is equal to the change in kinetic energy of the body.

So, As the force is applied in the same direction of the distance traveled,so only the kinetic energy of the body changes as after application of force, the speed of the body changes.

Answer:

v=wr

Explanation:

<u>Tangent and Angular Velocities</u>

In the uniform circular motion, an object describes the same angles in the same times. If \theta is the angle formed by the trajectory of the object in a time t, then its angular velocity is

\displaystyle w=\frac{\theta}{t}

if \theta is expressed in radians and t in seconds the units of w is rad/s. If the circular motion is uniform, the object forms an angle 2\theta in 2t, or 3\theta in 3t, etc. Thus the angular velocity is constant.

The magnitude of the tangent or linear velocity is computed as the ratio between the arc length and the time taken to travel that distance:

\displaystyle v=\frac{\theta r}{t}

Replacing the formula for w, we have

\boxed{ v=wr}

What acceleration will result when a 12 N net force applied to a 3 kg object?​
geniusboy [140]

Answer:

4m/s

Explanation:

due to newtons second law of motion

the accelerations that result when a 12-N net force is applied to a 3-kg object. A 3-kg object experiences an acceleration of 4 m/s/s.

How does dna make a copy of itself?
Sergeu [11.5K]
DNA is duplicated when two strands od DNA molecule complementary base pairs, the nucleotide has enough information needed to duplicate or if its Asexual meaning one parent dna will duplicate itself through the cells while sexual meaning two parents are involved you need both parents DNA to duplicate by the nucleotide.
