Answer:
Momentum is conserved.
All of the others are not conserved because of heat loss caused by deformation, etc.
4 blocks north because he is it not asking for north east
Fluid Friction exists when it is acted upon an object when in fluid.
Answer:
wave speed of the second wave 55.1 m/s
Explanation:
The wave speed of the second wave will going to be same i.e 55.1 m/s. As speed of wave is dependent on the medium and here in this case medium is remain same for second wave also i.e string only, no change in the medium noticed, therefore speed of second wave still remain same i.e 55.1 m/s.
Answer:
9] V = D ÷ T
Take any distance value from the graph and its relevant time.
V = 4 ÷ 2
V = 2 m/s
[You will notice that any distance values with its time will give you 2 m/s as its speed. This means that speed is constant throughout.]
10] Take the distance value and its time for the highest peak of B.
V = 20 ÷ 2
V = 10 m/s
