Answer:
Momentum, p = 7.2 g-m/s
Explanation:
It is given that,
The momentum of an object is
We need to express momentum in any equivalent units. There can be many solutions of this problem. Some of the units of mass are gram, milligram etc. units of length are meters, mm etc.
Since, 1 kg = 1000 gram
So,
Therefore, the momentum of the object is 7.2 g-m/s. Hence, this is the required solution.
Answer:
B.3 m/s
Explanation:
We are given that
Wavelength deep water wave=30 m
Time period=T=10 s
We have to find the velocity of deep water wave.
We know that the frequency=
Velocity, V=
Substitute the values in the formula
Then, we get
Velocity of deep water wave=
Hence, the velocity of deep water wave=3 m/s
Option B is true.
