Answer:

Non-uniform velocity as the laser light beam has got reflected by the mirror

And as the light got reflected there is a change in velocity making it non-uniform velocity

The speed of an object and the direction in which it moves constitute a vector quantity known as the velocity. an ostrich is run

Orlov [11]

Velocity of an object is its rate of change of the object's position per interval of time. Velocity is a vector quantity which means that it consists of a magnitude and a direction. Magnitude is represented by the speed and the direction is represented by the angle. To determine the velocity components, we use trigonometric functions to determine the angle of the components. For the north component we, use the sine function while, for the west component, we use the cosine function. We calculate as follows:
north velocity component = (16.8 m/s) (sin 54°) = 16.4 m/s
<span>west velocity component = (16.8 m/s) (cos 54°) = 3.49 m/s</span>

Real world situation to explain the relationship between work and power

In-s [12.5K]

-- You and your partner both get the same job to do:

Each of you gets a pallet of bricks, and you have to
put the bricks up on the bed of a truck, by hand.
Both pallets have the same number of bricks.

The pallet is way too heavy to lift, so you both cut the bands
that hold the bricks, and you lift the bricks from the pallet onto
the truck, by hand, two or three or four bricks at a time.

-- You get your pallet of bricks onto the truck in 45 minutes.

-- Your partner gets his pallet of bricks onto the truck in 3 days.

-- Work = (force) times (distance).

    You and your partner both lifted the same amount of weight
   up to the same height. You both did the same amount of work.

-- Power = (work done) divided by (time it takes to do the work) .

   Your partner took roughly 96 times as long as you took
   to do the same amount of work.
   You did it faster. He did it slower.
   You produced more power. He produced less power.

Question 2 (1 point)

HACTEHA [7]

Answer:

Actually, there is no force (felt by the object) acting on the object.

It is similar to an object in orbit around the earth (weightlessness)

F = M a describes the motion of the particle where

M a = M g where the acceleration of the particle is equal to the force of gravity acting on the particle

From an external view the only force acting on the particle is M g and it produces an acceleration of M g

Nostrana [21]

Answer: After a successful military career, Tiberius Gracchus went into politics trying to bring massive reforms to the military to its strength and morale.

In the last hundred years, there had been several wars. Since the standard time served in the Roman army was twenty years, often times soldiers would leave their farms in the hands of wives and children. As farms in this situation went steadily into bankruptcy and were bought up by the wealthy upper class, latifundi or large estates, were formed.

When the soldiers returned they had no where to go, so they went to Rome to join the mob of thousands of unemployed who roamed the city. Faced with this, the option of joining the army was unattractive, and number of soldiers and thus the power of Rome was shrinking.

In 133 BC Tiberius proposed a law called Lex Agraria saying that the government would buy the land owned by the Patricians in excess of 500 acres. This land would then be distributed to soldiers upon completion of their service. This would solve two problems, attracting new recruits and also taking care of homeless war veterans.

There was no question that the Patricians would get reimbursed because the Senate approved finances and they were also the ones who held most of the land. However, the bill was still unfeasible because there was not enough money currently to reimburse the Patricians without disrupting other activities. Then by chance that same year, king Attalus[?] of Pergamon died and left his entire fortune to Rome. Tiberius proposed that Attalus� fortune be used to fund the new law.

Tiberius was one tribune and then there was one other. Each tribune had the power to veto the law, thus both had to agree. As Tiberius proposed the bill to the Senate, the other tribune threatened to veto, so Tiberius had him removed from the Senate so that he would be unable to deliver the veto, and the bill became law. However Tiberius offeneded many in the Senate with his personality, and as a result a group of Senators and their supporters killed Tiberius with a group of followers in the streets of Rome.

This represents the first instance where the man with the most thugs was the one to gain power. This set a dangerous precedent, one that would signal the long decline of the republic of Rome
