The correct answer to the question is : Light or any electromagnetic wave.

EXPLANATION :

Before going to answer this question, first we have to understand refraction.

Refraction is the optical phenomenon in which light ray will bend at the interface of the two media having different optical densities.

When light ray comes from optical rarer medium to optical denser medium, the ray will bend towards the normal. It is so because the velocity of light in rarer medium is more than velocity of light in denser medium.

When the light comes from optical denser medium to optical rarer medium, the light ray bends away from the normal. It is so because the velocity of light increases in the rarer medium.

As per the question, wave is moving from air to ocean, and its velocity slows down.

Hence, there is refraction. So, the wave must be light or any electromagnetic wave.

When you bent the plastic ruler, what did you observe in its size?

WARRIOR [948]

Answer:

The size will increase.

Explanation:

When you bend a plastic ruler, it's size will increase because it is elastic and will exhibit elastic deformation. When it is been bent, it will continue to stretch until it get to a point where it will not be able to regain it formal shape, it size wound of increase. Therefore when the ruler get to elastic limit and you have bend it to the point it cannot regain it's formal shape back, it will remain bent and if further force is apply on it,it will break.

A 2.35-kg rock is released from rest at a height of 21.4 m. Ignore air resistance and determine (a) the kinetic energy at 21.4 m

kvasek [131]

Explanation:

Given that,

The mass of rock, m = 2.35-kg

It was released from rest at a height of 21.4 m.

(a) The kinetic energy is given by : $E_k=\dfrac{1}{2}mv^2$

As the rock was at rest initially, it means, its kinetic energy is equal to 0.

(b) The gravitational potential energy is given by : $E_p=mgh$

It can be calculated as :

$E_p=2.35\times 9.8\times 21.4\\\\E_p=492.84\ J$

M = 0 J + 492.84 J

M = 492.84 J

Hence, this is the required solution.

A truck travels up a hill with a 5.7° incline. The truck has a constant speed of 22 m/s. What is the horizontal component of the

tester [92]

Answer:

The horizontal component of the velocity is 21.9 m/s.

Explanation:

Please see the attached figure for a better understanding of the problem.

Notice that the vector v and its x and y-components (vx and vy) form a right triangle. Then, we can use trigonometry to find the magnitude of vx, the horizontal component of the velocity.

To find vx, let´s use the following trigonometric rule of right triangles:

cos α = adjacent / hypotenuse

cos 5.7° = vx / 22 m/s

22 m/s · cos 5.7° = vx

vx = 21.9 m/s

The horizontal component of the velocity is 21.9 m/s.

Which statement best describes a device that has a high energy efficiency? Its ratio of energy absorbed to energy released is hi

Stels [109]

Answer:

It wastes little energy

Explanation:

The efficiency of a machine refers to the ratio of work output to the work input as a percentage.
The efficiency of most machines is less than 100% because some work is lost due to friction and heat.
Therefore, a machine with high efficiency has less wastage of energy due to factors such as friction of the moving parts. Conversely, low efficiency means there is more wastage of energy.
