Answer:
Frequency = 3 Hz
Explanation:
Frequency is a measure of Hertz. Recall that Hertz is the unit expressing cycles/second, where one second is the denominator of the fraction for simplicity. If there are 12 waves every four seconds, and one wave represents one cycle, dividing 12 waves by 4 seconds will give the answer of 3 waves (or cycles) per one second.

0.000006kgm/s
Explanation:
Given parameters:
Mass = 0.01g
Velocity = 0.6m/s
Unknown:
Momentum = ?
Solution:
The momentum of a body is the product of its mass and velocity. It is subject to the impact a body in motion will have .
Momentum = mass x velocity
The unit is in kgm/s
We need to convert the mass to kilograms:
1000g = 1kg
0.01g = x kg ; 0.00001kg
Input the parameter:
Momentum = 0.00001 x 0.6 = 0.000006kgm/s
