Answer:
Value of angle between vector a and b is .
Explanation:
Vectors a and b have scalar product 6.00
Let be the angle between a and b.
ab cos = 6 ...(1)
Vectors a and b have magnitude of vector product 9.00
ab sin = 9 ...(2)
Dividing equation (2) by (1) we get
tan = 1.5
=
Thus, value of angle between vector a and b is .
It would be thrust, so the first one
Answer:
Explanation:
We are given that
Frequency,f=
Speed,v=40.2 m/s
We have to find the increase in frequency.
We know that
Speed of light,c=
The waves are reflected therefore the change in frequency at the gun is equal to twice the change in frequency.
Therefore, increase in frequency=
The ice melts a liquid the molecules spread out and when a liquid changes to a gas the molecules spread out more.
