Answer:

D. nine times yesterdays power output

Explanation:

We know that formula for power with work is;

Power = workdone/time taken

Now, you did three times the work in one-third the time yesterday.

This means that;

Work yesterday; W_yesterday = W

Work today; W_today = 3W

Time yesterday; T_yesterday = t

Time today; T_today = t/3

Thus,power today is;

P_today = 3W/(t/3)

P_today = 9(W/t)

Since power output yesterday is W/t, it means you did nine times yesterday's power output.

Answer:

D

Explanation:

Nine times yesterday's power output.

Answer:

1: 6.637e-13 N

2: 6.637e-09 N

3: 1.335e-08 N

4: 1.335e-08 N

5: 1.456e-06 N

6: 5.839e-07 N

7: 6.673e-11 N

I'd suggest double checking these if you can.

Explanation:

Each of these you can answer by plugging the numbers into the equation

[tex]F = G\frac{m_1 m_2}{r^2}[/tex]

G is the gravitational constant 6.673×10⁻¹¹ N m² / kg²

So the first one would be:

[tex]F = 6.673 \times 10^{-11} \frac{Nm^2}{kg^2} \times\frac{1kg\times 1kg}{(10m)^2}\\F = 6.673 \times 10^{-11} N \times\frac{1}{100}\\F = 6.673 \times 10^{-13}N[/tex]

I'm not going to run through showing all calculations for the rest, as you're in a rush, so to whip through them

2: 6.637e-09 N

3: 1.335e-08 N

4: 1.335e-08 N

5: 1.456e-06 N

6: 5.839e-07 N

7: 6.673e-11

Pardon the lack of superscript, I just punched these into a python console to calculate them.

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:

-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

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.

Answer:

During winter time the northern hemisphere leans away from the sun due to the rotation of earth and due to this change the sunlight is not direct on these areas instead it is spread and due to this the shadows are longer and the sunlight is not intense. The earths rotation around the sun causes the seasons to change and that is why we experience shorter hours of daytime.

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:

2800N

Explanation:

Given parameters:

Mass of car   = 1400kg

Acceleration  = 2m/s²

Unknown:

Force on the car  = ?

Solution:

To solve this problem, we use Newton's second law of motion.

        Force  = mass x acceleration

So;

         Force  = 1400 x 2  = 2800N

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:

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:

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:

-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
