The answer is 2. This is where the kinetic energy is being transferred into gravitational potential energy, and then there is complete gravitational potential energy at point 3. So the answer you are looking for is 2. I hope this helps :) please make brainliest

Position 4!! At position 4 , the roller coaster cart stores the most amount of kinetic energy. When its at position 4 , the kinetic energy of the cart will be converted to gravitational potential energy as the cart increases in height!!

I hope this answered ur qns!! ^^

Which action can humans take to reduce wave erosion?
mezya [45]

The action that  humans can take to reduce wave erosion is to build breakwaters in the ocean.

<h3>What is erosion?</h3>

The term erosion has to do with the washing away of top soil either by water or by wind. The control of erosion is a very important soil conservation effort.

Hence, the action that  humans can take to reduce wave erosion is to build breakwaters in the ocean.

An incident ray strikes a boundary at a 72.5-degree angle, resulting in an angle of refraction of 39.6 degrees. The index of ref
maks197457 [2]
A. Medium 1 is air. The refractive index of air is 1.0003. Refractive index is a measure of the bending of a ray of light when passing from one medium to another. If i is the angle of incidence of a ray in vacuum and r is the angle of refraction, the refractive index n is defined as the ratio of the sine angle of incidence to the sine of the angle of refraction; that is, n= sin i/ sin r. Refractive index may also be given by the velocity of light in medium 1 divided by the velocity of light in medium 2.


b. In this case the refractive index = sin 72.5/sin 39.6 
                                                   = 1.4962 
but n = x/ 1.0003 = 1.4962
Therefore; x = 1.4967
Hence the refractive index of medium 2 is 1.4967. 
I therefore think that medium 2 is toluene; since it has a similar refractive index.

inessss [21]
I think the correct answer from the choices listed above is the third option. The magnetic quantum number of an electron (m) designates the orientation in space of the orbital (electron cloud). <span>This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell. </span>
