Explanation:
It is given that,
Length of the string, l = 2 m
Mass of the string, 
Hanged mass in the string, 
1. The tension in the string is given by :
T = 1.96 N
2. Velocity of the transverse wave in the string is given by :
m = M/l
v = 28 m/s
Hence, this is the required solution.
The only statement on the options that says true about density is:> The density of an object determines whether it will sink or float.
Why?Density is a physical property of an object.
Density is not derived as a unit of measure. It is derived from 2 fundamental units: kg and m.
The Density of an object is not constant.
Density is calculated by dividing the mass by the volume of an object.

The density of an object determines whether it will sink or float.
Answer:
60 m/hr
Explanation:
Remember your equation d=r/t
Plug it in
Or you can think; if a person can run 240 m/hr that means that they can get 1/4 of the way in 1/4 of the time= 60 m
Answer:
Newton's third law
Explanation:
Newton's Third Law of equal and opposite forces is very important when considering collisions between objects or propulsion. In these situations, all of the forces are internal, which means that for every force, there will be an equally sized force in the opposite direction. An example is two skaters out on the ice.
