The properties of mechanical waves are : ( C and D )
- The three categories of mechanical waves are transverse, longitudinal,surface waves ( C )
- Waves transport energy,but not matter ( D )
<h3>What are mechanical waves ?</h3>
Mechanical waves are a category of waves which cannot transmit energy through a vacuum, i.e. they require a medium to transmit their energy from one end to another. An example of a mechanical wave is : sound wave. Mechanical waves are grouped into transverse, longitudinal and surface waves.
Hence we can conclude that The properties of mechanical waves are : The three categories of mechanical waves are transverse, longitudinal,surface waves and Waves transport energy,but not matter

Answer:
Its final velocity and how much time it takes to reach the water
Explanation:
The motion of the stone is a uniformly accelerated motion, so we can use the following suvat equation to determine its final velocity:

where
v is the final velocity
u = 0 is the initial velocity
is the acceleration of gravity
s = 52 m is the distance covered during the fall
Solving for v,

We can also find how much time it takes to reach the water, using the equation

where
v = 31.9 m/s is the final velocity
u = 0 is the initial velocity
t is the time
And solving for t,

Answer:
Explanation:
Given
charge on each Particle is Q
Length of diagonal of the square is 2a
therefore distance between center and each charge is 
Electric Potential of charged Particle is given by
For First Charge




total Electric Potential At center is given by


Given:
V1 = initial velocity = 24 m/s
a = acceleration = 2.0 m/s^2
s = time = 8 s
V2 = final velocity = ?
For linear-motion problems with those given terms, the following formula is used:
V2 = V1 + as
Substituting the given values:
V2 = 24 + 2(8)
V2 = 24 + 16
V2 = 40 m/s
Therefore the car will have a speed of 40 m/s as it leaves the tunnel.
