Answer:

The disturbance of molecules are perpendicular to wave motion

Explanation:

Transverse waves: in transverse waves all the medium moles vibrates perpendicular to the wave motion such that the net displacement of all molecules are zero.

While in longitudinal waves all the molecules will oscillate in the direction of wave propagation. All molecules transfer the energy from one point to other point while oscillating parallel to the wave propagation direction.

In an intergalactic competition, spaceship pilots compete to see who can cover the distance between two asteroids in the short-
pogonyaev

Answer:

a)  truc is C,  b) correct result is the B

Explanation:

As the speed of the competition is very high, for the judges the speed is

           v = d / t

           v = 3 109 m / 20

           v = 1.5 108 m / s

This is half the speed of light. For these high speeds we must use the relations of special relativity.

For the time          t = to γ

For distance         L = Lo / γ

                            γ = √ (1-v2 / c2)

Own time and distance (to and Lo) corresponds to the observer who is not moving the judges in this case

Let's look for the range value

                     γ = 1 / √ (1 - (1.5 / 3) 2) = 1 / 0.866 = 1.15

The time              t = 20 1.15 = 23 s

The distance       L = 3 10 9 /1.15 = 2.60 109 m

From these results we see that time increases and the distance is shorter.

Let's review the claims

A) False. It's the opposite

B) False

C) True. It is according to the result found

D) False.

In the nuclear fusion process, we will also use the special relativity that has a relationship between energy and mass

         ΔE = c² Δm

As in the process energy is released, for the law of conservation of the mass of energy to be fulfilled, the total mass of the products, He atom, must be reduced.

Therefore the correct result is the B

Friction is just hot air rubbing off the inevitable force of solid <br> prove me wrong
Lorico [155]

Answer:

friction is when two objects tough with force basically. when an object is rubbed against something. when an object comes in contact with something else. or ig u can call it hot air rubbing off the inevitable force lol that works too , bud

Jane, looking for tarzan, is running at top speed (5.2 m/s) and grabs a vine hanging 4.5 m vertically from a tall tree in the ju
kumpel [21]
While Jane is running has a kinetic energy, which is Ek = 1/2*m*v^2 where m is mass and v is velocity  When she grabs a vine, she is going to change the kinetic energy to potential energy.  
We know that potential energy is given by Ep = m*g*h where m is mass, g is gravity constant and h is height  
So while running the kinetic energy is Ek = 1/2 * m * 5.2^2 = 13.52*m 
Then all that energy is used to swing upward and gain potential energy 
Ep = m*g*h = Ek = 13.52*m  
m*9.8*h = 13.52*m 
h = 13.52/9.8 = 1.38 meters  
So Jane will swing 1.38 meters upward
