What is refraction of light?

Refraction is the change in direction of a wave when it passes from one medium to another or from a gradual to a sudden change in the medium.

When a wave of light passes from one medium to another, its direction is changed. This phenomenon is called refraction. It occurs because the speed of light is different in different media.

The amount of refraction that occurs depends on the difference in the speed of light in the two media, and the angle at which the light wave is incident on the boundary between the two media. The greater the difference in the speed of light, the greater the amount of refraction. The angle of incidence also affects the amount of refraction; the greater the angle, the greater the refraction.

Answers

The force experienced by the truck driver is lesser than the force experienced by a car driver in a perfectly inelastic collision.

According to law of conservation of momentum,

m1 u1 + m2 u2 = m1 v1 + m2 v2

After perfect inelastic collision,

v1 = v2

m1 u1 + m2 u2 = ( m1 + m2 ) v

u1 = 8 m / s

u2 = - 8 m / s

m1 = 3800 kg

m2 = 830 kg

Substituting the known values,

( 3800 * 8 ) - ( 830 * 8 ) = ( 3800 + 830 ) v

30400 - 6640 = 4630 v

v = 6.43 m / s

Since final velocity is positive, the vehicles will  move the direction of truck after collision.

For the truck,

a = ( 6.43 - 8 ) / 0.15

a = - 10.48 m / s²

F = 3800 * - 10.48

F = - 39.83 KN

For the car,

a = ( 6.43 - ( - 8 ) ) / 0.15

a = 96.2 m / s²

F = 830 * 96.2

F = 79.85 KN

I Ft I < I Fc I

Therefore, the force experienced by the truck driver is lesser than the force experienced by a car driver.

The given question is incomplete. The complete question is:

Most of us know intuitively that in a head-on collision between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Why is this?

To substantiate this view, they point out that the car is crushed, whereas the truck is only dented. This idea of unequal forces, of course, is false. Newton's third law tells us that both objects experience forces of the same magnitude. The truck suffers less damage because it is made of stronger metal. But what about the two drivers? Do they experience the same forces? Suppose that each vehicle is initially moving at 6.40 m/s and that they undergo a perfectly inelastic head-on collision. Each driver has mass 81.0 kg.

The inner planets are Planets C , D and E.

The outer planets are Planets A. B and F.

How many types of planets are there in our Solar System?

Astronomers frequently divide our Solar System's planets into two groups: the inner planets and the outer planets.

Inner Planets

Due to their position, nearer to the Sun, the inner planets are smaller and more rocky. Mercury, Venus, Earth, and Mars are the inner planets, which are listed in order of proximity to the sun from closest to farthest. The four inner planets are referred to as "terrestrial planets" because they have solid surfaces and, as suggested by their names, are fairly similar to Earth. However, the term can be deceptive because the conditions on each of the four worlds vary greatly. They have either no moons or few moons, are primarily composed of heavy metals like iron and nickel, and are small in size.

Outer Planets

The outer planets are much larger in size, farther distant, and mostly composed of gas.Jupiter, Saturn, Uranus, and Neptune are the outer planets that appear after an asteroid belt.The outer planets are large, gas-encased planets that are also referred to as gas giants or Jovian planets. Each has a large number of moons and each has rings. Even though they are large, only Jupiter and Saturn are visible without telescopes. Astronomers learned the solar system was larger than previously believed when Uranus and Neptune, the first planets identified since antiquity, were discovered.

On the basis of the above comparison the planets in the question are classified as-

Planet A - Outer Planet as has 67 moon, and major part of it atmophere are hydrogen and helium.

Planet B - Outer Planet as has ring but not much atmophere.

Planet C - Inner Planet as has no moon but has high volcanic activity

Planet D - Inner Planet as has high amount of carbon dioxide in it atmophere and has two moon

Planet E - Inner Planet as  has a thin layer of atmophere but no moon due to the effect of the Sun’ gravity

3. below is a 4-bit up-counter. what is the largest number of the counter if the initial state q3q2q1q0

Answers

The largest number is 1111. Option A.

The initial state in a state or activity diagram. Represents the state of an object before the events contained in the diagram act on it. Transitions from initial states are usually unlabeled and represent transitions to enclosing states. A final state marks the end of the execution flow of a state machine or region.

Can have multiple incoming transitions but no outgoing transitions. Each region can have at most one final state. For orthogonal regions, execution flow stops when all region end conditions are reached. In quantum state terms, colliding particles form an initial state. In a collision, particles can be annihilated and/or exchanged resulting in a different set of particles in the final state.

She was a Russian Princess, and had driven all the way from Finland in a sledge drawn by six reindeer. The sledge was shaped like a great golden swan, and between the swan's wings lay the little Princess herself. Her long ermine-cloak reached right down to her feet, on her head was a tiny cap of silver tissue, and she was as pale as the Snow Palace in which she had always lived. So pale was she that as she drove through the streets all the people wondered. "She is like a white rose!" they cried, and they threw down flowers on her from the balconies.(2) At the gate of the Castle the Prince was waiting to receive her. He had dreamy violet eyes, and his hair was like fine gold. When he saw her he sank upon one knee, and kissed her hand.(3) "Your picture was beautiful," he murmured, "but you are more beautiful than your picture"; and the little Princess blushed.(4) "She was like a white rose before," said a young Page to his neighbor, "but she is like a red rose now"; and the whole Court was delighted.(5) For the next three days everybody went about saying, "White rose, Red rose, Red rose, White rose"; and the King gave orders that the Page's salary was to be doubled. As he received no salary at all this was not of much use to him, but it was considered a great honor, and was duly published in the Court Gazette.(6) When the three days were over the marriage was celebrated, and it was a magnificent ceremony, and the bride and bridegroom walked hand in hand under a canopy of purple velvet embroidered with little pearls. Then there was a State Banquet, which lasted for five hours, where the Prince and Princess sat at the top of the Great Hall and drank out of a cup of clear crystal. Only true lovers could drink out of this cup, for if false lips touched it, it grew grey and dull and cloudy.(7) "It's quite clear that they love each other," said the little Page, "as clear as crystal!" and the King doubled his salary a second time.(8) "What an honor!" cried all the courtiers.Which line best shows that the King was delighted by the Pages remark about the Princess?

Then the weight of the oil and the weight of the water combine to create the pressure at the bottom. Why does air pressure decrease with increasing altitude? (Select all that apply.) Less air above pushes down. Hot air rises. The weight of the air above is smaller. Colder air is less dense. There is more air below to push up more strongly. The weight of the air below is smaller. Use the worked example above to help you solve this problem. In a huge oil tanker, salt water has flooded an oil tank to a depth of h_2 = 4.75 m. On top of the water is a layer of oil h_1 = 8.40 m deep, as in the cross-sectional view of the tank as shown in the figure. The oil has a density of 0.700 g/cm^3. Find the pressure at the bottom of the tank. (Take 1,025 kg/m^3 as the density of salt water.) Calculate the pressure on the top lid of a chest buried under 3.80 meters of mud with density 1.75 x 10^3 kg/m^3 at the bottom of a 11.5-m-deep lake. skysong realty corporation purchased a tract of unimproved land for $55,000. this land was improved and subdivided into building lots at an additional cost of $34,460. these building lots were all of the same size but owing to differences in location were offered for sale at different prices as follows. group 1 2 3 no. of lots 9 15 17 price per lot $3,000 4,000 2,400 a operating expenses for the year allocated to this project total $18.200. lots unsold at the year-end were as follows. group 1 group 2 group 3 4 lots 6 lots 1 lots at the end of the fiscal year skysong realty corporation instructs you to arrive at the net income realized on this operation to date.
