Which of the following are properties of mechanical waves?
yuradex [85]

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

A stone is dropped into water from a bridge 52 m above the water's
dusya [7]

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:

v^2-u^2=2as

where

v is the final velocity

u = 0 is the initial velocity

a=g=9.8 m/s^2 is the acceleration of gravity

s = 52 m is the distance covered during the fall

Solving for v,

v=\sqrt{u^2+2as}=\sqrt{0^2+2(9.8)(52)}=31.9 m/s

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

v=u+at

where

v = 31.9 m/s is the final velocity

u = 0 is the initial velocity

a=g=9.8 m/s^2

t is the time

And solving for t,

t=\frac{v-u}{a}=\frac{31.9-0}{9.8}=3.26 s

Four point charges are placed at the corners of a square. Each charge has the identical value +Q. The length of the diagonal of
kvv77 [185]

Answer:V_{net}=4\frac{kQ}{a}    

Explanation:

Given

charge on each Particle is Q

Length of diagonal of the square is 2a

therefore distance between center and each charge is \frac{2a}{2}=a

Electric Potential of charged Particle is given by

For First Charge

V_1=\frac{kQ}{a}

V_2=\frac{kQ}{a}

V_3=\frac{kQ}{a}

V_4=\frac{kQ}{a}

total Electric Potential At center is given by

V_{net}=V_1+V_2+V_3+V_4

V_{net}=4\times \frac{kQ}{a}

V_{net}=4\frac{kQ}{a}

A car enters a tunnel at 24 m/s and accelerates steadily at 2.0 m/s2. At what speed does it leave the tunnel, 8.0 seconds later?
Bogdan [553]
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.
