Answer:
c) What is the ratio K2/K1 of their kinetic energies?
Explanation:
S= 343m/s
F=256Hz
WL= 343ms/256-1
WL=V/F
= 1.339844m
It is same as calculating maths for math
Acceleration = velocity / time.
The microwave ovens rotate at a rate of about 0.105 rev/s.
The microwave rotation is the number of revolutions in a unit of time. To change the unit for angular velocity, assume that the quantity is multiplied by the unit it has. Then change to the desired units. The angular velocity is denoted by ω and has a magnitude of 6.3 rev/min.
ω = 6.3 rev/min

- 1 minute = 60 seconds
- The revolution unit didn't change


ω = 0.105 rev/s
