Answer:
Explanation:
Expression for velocity of wave produced in a hanging wire can be given as follows
Velocity v = 
where T is tension in wire and m is mass of wire per unit length.
In the given case
T = Mg + mg
= Mg
neglecting weight of rope
mass of the rope per unit length
= m / L
Velocity of wave
= 
= 
Answer:
1. B has no acceleration because the straight line shows that it's a constant speed not speeding up or down.
2. A because you can see the decline in speed as time goes on
Answer:
t = 0.0735 m
Explanation:
Angular acceleration of the flywheel is given as
now after t = 8 s the speed of the flywheel is given as
now rotational kinetic energy of the wheel is given as
now we have
Gas "floats" so if there are examples or pictures it would be the one with the most evenly spread out "dots".
