Answer:

The color that is refracted the most has the shortest wavelength

Explanation:

The warmer colors (yellow to red) have shorter wavelengths and the colder (green to violet) shorter wavelengths. Bearing in mind that light is radiant energy, the shorter the wavelength, the greater the frequency and the greater the amount of energy, allowing colors with shorter wavelengths to be more refracted.

The light can reflect in several ways but it follows a law: the angle of incidence is the same as the starting angle. If the light reflects on a perfectly smooth surface, such as in a mirror (which is glass with a silver film), the light will be reflected exactly as it did. That is why we see an image totally faithful in form and color when we see ourselves in the mirror. But if the object is not smooth, it will reflect part of the incident light and absorb the rest. The illumination of this object will reveal only its own color, shape, texture and not the image of a reflection. Black objects absorb light completely and white objects reflect it completely. The colorful visual sensation of objects, in fact, is the detection and perception of the wavelength that they are reflecting.

The color that is refracted the most has the SHORTER wavelength. The shorter the wavelength,the more it gets refracted.

A ball rolls down the hill which has a vertical height of 15 m. Ignoring friction what would be the gravitational potential ener

trasher [3.6K]

a) Potential energy: 147 m [J]

The gravitational potential energy of an object is given by

$U=mgh$

where

m is its mass

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

h is the height of the object above the ground

In this problem,

h = 15 m

We call 'm' the mass of the ball, since we don't know it

So, the potential energy of the ball at the top of the hill is

$U=(m)(9.8)(15)=147 m$ (J)

b) Velocity of the ball at the bottom of the hill: 17.1 m/s

According to the law of conservation of energy, in absence of friction all the potential energy of the ball is converted into kinetic energy as the ball reaches the bottom of the hill. Therefore we can write:

$U=K=\frac{1}{2}mv^2$

where

v is the final velocity of the ball

We know from part a) that

U = 147 m

Substituting into the equation above,

$147 m = \frac{1}{2}mv^2$

And re-arranging for v, we find the velocity:

$v=\sqrt{2\cdot 147}=17.1 m/s$

car is moving at 40 m/s. At 10 meters the driver spots a deer on the road and instantly steps on the brakes. If the car is 400 k

Mice21 [21]

Answer:

32000 N

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 40 m/s

Distance (s) = 10 m

Final velocity (v) = 0 m/s

Mass (m) of car = 400 Kg

Force (F) =?

Next, we shall determine the acceleration of the the car. This can be obtained as follow:

Initial velocity (u) = 40 m/s

Distance (s) = 10 m

Final velocity (v) = 0 m/s

Acceleration (a) =?

v² = u² + 2as

0² = 40² + (2 × a × 10)

0 = 1600 + 20a

Collect like terms

0 – 1600 = 20a

–1600 = 20a

Divide both side by –1600

a = –1600 / 20

a = –80 m/s²

The negative sign indicate that the car is decelerating i.e coming to rest.

Finally, we shall determine the force needed to stop the car. This can be obtained as follow:

Mass (m) of car = 400 Kg

Acceleration (a) = –80 m/s²

Force (F) =?

F = ma

F = 400 × –80

F = – 32000 N

NOTE: The negative sign indicate that the force is in opposite direction to the motion of the car.
