The formula is wavelength=speed÷frequency so if you do 15÷9 which equals 1.6
Answer:
There is no kinetic energy.
Explanation:
Since K=1/2mv^2 where m=2122kg and v=0, clearly the car has no kinetic energy as multiplying by 0 results in 0. If the car were moving, there would be kinetic energy.
The particles in diagram 3 move fast enough to break away from each other.
Answer:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object
