Answer:

B

Explanation:

The object with the most thermal energy is the choice B. This is because from the given choices, it has the most mass and highest temperature of all the bricks.

Thermal energy is the sum total of the average kinetic energy within the system.

It is mathematically expressed as:

    Quantity of energy  = mass   x  specific heat x  change in temperature

We see that the quantity of the thermal energy is directly proportional to mass and temperature changes.

Answer:

B. a 4 kg brick at 25 degrees Celsius

Answer:

ALWAYS ( in all cases and at all times)

Explanation:

From Newton's 3rd Law of motion which states that every action that occurs (force) there will be equal as well as opposite reaction. Therefore as the man is pushing the chair exerting 50N force, the chair also is is exerting equal force as well as opposite force on him as he is pushing it

Answer:

The wavelength of the waves traveling along the string is 12 meters.

What is a Wavelength?

Given:

Waves propagate along the stretched string at speed = 8.0 m/s

The end of the string vibrates up and down once every 1.5 s.

∴ Time = 1.5 s

We have to find the wavelength of the waves.

We know,

⇒ Time = 1/frequency

⇒ 1/frequency = 1.5

Now

⇒ speed = frequency × wavelength

⇒ wavelength = speed / frequency

⇒ wavelength = 8 × 1.5

⇒ wavelength = 12 m

Therefore, the wavelength of the waves traveling along the string with given speed is 12 m.

Explanation:

Answer: The greater an object's mass, the more gravitational force it exerts.

Explanation: So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. Sorry if I get this wrong. I am in 5th grade! ♥

The gravitational attraction between the Sun and Earth is stronger than the attraction between the Sun and the Moon, principally because of the Sun's greater mass and greater distance from Earth.

An object's mass affects how much gravitational pull it exerts. Both the Earth and the Moon are much less massive than the Sun. Approximately  330,000 times more massive than the Earth, and roughly 27 million times more massive than the Moon, is the Sun. Because of the Sun's greater mass, its gravitational pull is thus much stronger.

The strength of the gravitational force between two objects is greatly influenced by their distance from one another. The Sun and Earth are separated from one another by a far smaller distance than the Sun and Moon. The Sun is located roughly 150 million kilometers from Earth, while the Moon is located roughly 384,400 kilometers from the Sun on average. The inverse square law asserts that the gravitational force decreases with increasing distance, and that it is only one-fourth as strong when two objects are twice as far apart.

Hence, the gravitational force between the sun and earth is larger than the sun and the moon due the mass of the sun and earth is greater than the moon and sun. The distance between the sun and the earth is comparatively smaller than the distance between the sun and the moon.

Answer:

-5m/s²

Explanation:

Given parameters:

Initial velocity  = 25m/s

Time  = 5s

Final velocity  = 0m/s

Unknown:

Acceleration of the car  = ?

Solution

The acceleration of a body is the rate of change of the velocity of the body with time.

 Acceleration  = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]  

So;

 Acceleration  = [tex]\frac{0 - 25}{5}[/tex]    = -5m/s²

The car is decelerating at a rate of  5m/s²

Answer:

1. Displacement can be positive OR negative. The sign implies the direction of the displacement. 2. In one dimension the direction is indicated by the sign: negative if to the left and positive if to the right.

Answer:

6m/s²

Explanation:

Given parameters:

Initial velocity  = 35m/s

Final velocity  = 65m/s

Time taken  = 5s

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time taken;

   Acceleration  = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]  

So;

 Acceleration   = [tex]\frac{65 - 35}{5}[/tex]    = 6m/s²

Answer:

Answer:

2.4m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time 25s

Final velocity  = 60m/s

Unknown:

Acceleration  = ?

Solution:

Acceleration is the rate of change of displacement

      Acceleration  = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]

    Acceleration  = [tex]\frac{60 - 0}{25}[/tex]    = 2.4m/s³

C.cytoplasm

Answer:

q₂ = 0.0002 C

Explanation:

Given that,

Charge, q₁ = -0.0005 C

The force between two charges, F = 9 N

The distance between charges, d = 10 m

We need to find the magnitude of the second charge. The force acting between two charges is given by :

[tex]F=\dfrac{kq_1q_2}{r^2}\\\\q_2=\dfrac{Fr^2}{kq_1}\\\\q_2=\dfrac{9\times (10)^2}{9\times 10^9\times 0.0005}\\\\q_2=0.0002\ C[/tex]

So, the magnitude of the second charge is 0.0002 C.

Answer:

15m/s²

Explanation:

Given parameters:

Initial velocity  = 10m/s

Final velocity  = 40m/s

Time taken  = 2s

Unknown:

Average acceleration  = ?

Solution:

Acceleration is the rate of change of velocity with time;

 Acceleration  = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]  

  Acceleration = [tex]\frac{40 - 10}{2}[/tex]    = 15m/s²

That's the Ampere.

1 Ampere = 1 Coulomb of charge per second.

Answer:

The moon its self does not generate life.

Explanation:

Moon phases are determined by the relative positions of the Moon, Earth, and Sun.  Instead, the Moon's phase depends only on its position relative to Earth and the Sun. The Moon doesn't make its own light, it just reflects the Sun's light as all the planets do. The Sun always illuminates one half of the Moon.

The International Space Station was  built from separate parts sent to space.

A sizable spacecraft in orbit orbiting the Earth is called the International Space Station. Crews of astronauts and cosmonauts reside there as a home. The space station serves as an exceptional science lab. The space station was created and used by international cooperation.

The components of the space station were put together by astronauts while they were in space. It travels around 250 miles above Earth's surface on its typical orbit. It has a speed of 17,500 mph. It therefore orbits the planet every 90 minutes. The space station is being used by NASA to learn more about surviving and operating in space. These discoveries will enable sending more people into space than ever before.

For the entire space station, there is no set ownership stake. Instead, each partner should maintain authority and control over the elements it registers and over employees in or on the Space Station who are its nationals, according to Article 5 of the IGA. As a result, only one partner holds sole control of each ISS module. However, the contracts for using the space station's amenities are more intricate.

Answer:

-They will be available for many years.

Explanation:

The advantage of using renewable resources is that they will be available for many years.

Renewable resources have very fast turn over time for replenishing, therefore, they are available over an extended period time.

They are not used by consumption and so they will continually be available. This is different from the non-renewable resources which are depleted as they are being used up.

Examples of renewable resources are wind, water and air
