What is the speed of light?

Answers

Answer 1

Answer:

299792458 meters per second (approximately 300000 km/s or 186000 mi/s)

Explanation:

The speed of light in vacuum, commonly denoted c, is a universal physical constant that is important in many areas of physics. Its exact value is defined as 299792458 meters per second (approximately 300000 km/s or 186000 mi/s).[Note 3] According to the special theory of relativity, c is the upper limit for the speed at which conventional matter, energy or any signal carrying information can travel through space.

3. How can the U.S. economy grow if we import more goods and services?

Answers

The U.S. economy grow via trade deficit,  if we import more goods and services.

What is import and export?

When any good or service is  brought in from one country to another is called Import while exports are when goods and services produced in the home country for sale to other countries.

If a country imports more than it exports, it runs a trade deficit. If it imports less than it exports, that creates a trade surplus. When a country has a trade deficit, it must borrow from other countries to pay for the extra imports.

Thus, the U.S. economy grow via trade deficit,  if we import more goods and services.

The velocity of the rocket is not the same as the speed of the rocket. What is the difference between the velocity of an object and the speed of an object

Answers

The difference between the velocity of an object and the speed of an object is that the velocity represents both the magnitude and direction, and speed represents only the magnitude.

What is velocity?

Velocity is the time rate of change of displacement.

Speed is the ratio of distance and the time taken to travel that distance.

Thus, the difference between the velocity of an object and the speed of an object is that the velocity represents both the magnitude and direction, and speed represents only the magnitude.

If this Answer helped, please mark it as Brainliest. Thank you!

You find the answer by solving the problem.


You can solve the problem by using the equation that tells how force, mass, and acceleration are connected.


The equation is in the "Hint".


F = m • a


Force = mass • acceleration


mass = 200 kg


acceleration = 2 m/s^2


Force = (2000 kg) • (2 m/s^2)


Force = 400 Newtons

What is observed as the distance between the rest position and the crest of a light wave decreases?

A. The light becomes more violet
B. The light becomes dimmer
C. The light becomes brighter
D. The light becomes more red

Answers

Answer: answers B

Explanation: it gets dimmer becuase less light......

As it is observed the distance between the rest position and the crest of a light wave decreases, and the light becomes dimmer, therefore the correct answer is option B.

What is Wavelength?

It can be understood in terms of the distance between any two similar successive points across any wave for example wavelength can be calculated by measuring the distance between any two successive crests.

C = λν

As given in the , it is observed the distance between the rest position and the crest of a light wave decreases,

The right response is option B since it can be seen that when the distance between the rest position and the crest of a light wave decreases, the light becomes dimmer.

b. Describe how the arrangement of the books can be changed for the greatest overall potential energy when only one book is on each shelf.

Answers

a.  P.E(Y)<  P.E(W)<  P.E(Z)<  P.E(X)

b. The books arranged with book X in the bottom, book Z in 2nd position, book W in 3rd and book Y on the top.

What is gravitational potential energy?

If an object is lifted, work is done against gravitational force. The object gains energy.

The equation for calculating gravitational potential energy is

GPE =mgh

where, GPE is the gravitational potential energy, m is the mass, h is the change in height and g is the acceleration due to gravity.

a) According to the heights of books, P.E(Y)<  P.E(W)<  P.E(Z)<  P.E(X)

when arranged for lowest potential energy, book with the lowest mass will be placed in the lower position. Thus, relationship among masses, m(Y)< m(W)<m(Z)<m(X)

b)  The arrangement of the books can be changed for the greatest overall potential energy when only one book is on each shelf. The books arranged with book X in the bottom, book Z in 2nd position, book W in 3rd and book Y on the top.
