The figure above shows the position of a moon that orbits a planet in an elliptical path. Two specific locations of
the moon, position and position , are labeled.

1. As the moon orbits the planet from position to position , is the magnitude of the planet’s force due to
gravity exerted on the moon constant? Why or why not?
A
Yes, because the masses of the planet and moon remain constant.

B
Yes, because the elliptical path that the moon travels around the planet is the same for all revolutions.

C
No, because the tangential speed of the moon is always changing.

D
No, because the moon’s distance from the planet is always changing.

The Figure Above Shows The Position Of A Moon That Orbits A Planet In An Elliptical Path. Two Specific

Answers

Answer 1

It is evident that the force due to gravity exerted on the moon is not constant because the  moon’s distance from the planet is always changing.

What is the gravitational force?

The gravitational force is the force of attraction that brings two masses together in the universe. We have to note that the gravitational force is an attractive force and that all of the objects that are found on the surface of the earth are under the gravitational filed of the earth.

Now we know that the distance that exists between the the moon as it is orbiting round the sun is always changing. We know that the gravitational force depends on the masses as well as the distance.

What’s the difference between mechanical and chemical weathering

Answers

Answer:

Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes.

Explanation:

Mechanical weathering (also called physical weathering) breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller. That means the rock has changed physically without changing its composition. The smaller pieces have the same minerals, in just the same proportions as the original rock.

Chemical weathering is the other important type of weathering. Chemical weathering is different from mechanical weathering because the rock changes, not just in size of pieces, but in composition Chemical weathering works through chemical reactions that cause changes in the minerals.

A car travels along a straight road to the east for

100 meters in 4 seconds, then has to turn around

and goes back west for 50 meters in 1 second.

Determine average speed and average velocity.

Answers

Answer: 90 m/s, 70 m/s

Explanation:

Given

A car travels 100 m  east for 4 seconds and then turn around

goes back west for 50m  in 1 sec

Distance traveled in the east is [tex]100\times 4=400\ m[/tex]

Distance traveled in the west is [tex]50\times 1=50\ m[/tex]

Total distance[tex]=400+50=450\ m[/tex]

total displacement[tex]=400-50=350\ m[/tex]

total time [tex]t=4+1=5\ s[/tex]

Average speed

[tex]\Rightarrow s_{avg}=\dfrac{\text{distance}}{\text{time}}=\dfrac{450}{5}\\\\\Rightarrow s_{avg}=90\ m/s[/tex]

Average velocity

[tex]\Rightarrow v_{avg}=\dfrac{\text{displacement}}{\text{time}}=\dfrac{350}{5}\\\\\Rightarrow v_{avg}=70\ m/s[/tex]

How much impulse is applied by a 25 N force in 30 seconds?

Answers

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the Impulse.

Impulse is denoted by 'J'

hence, J = F. dt

so we get as,

J = (25)*(30)

J = 750 N-s

===> hence the impulse is 750 N-s

Impulse is applied by a 25 N force in 30 seconds is 750 N-s.

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

An old woman is worried about time. She walks at a rate of 2 meters per second and travels a
distance of 454 meters. How long does it take her to complete the motion?


Please help ASAP!! BRAINLIST please explain thankyou!!!

Answers

Answer:

227 seconds.

Explanation:

Speed is equal to distance divided by time. s = d/t

We can rearrange this algebraically to solve for the time it will take to cover a certain distance at a certain speed. Time is equal to distance divided by speed.  t = d/s

Then we substiture our known values for the variables and solve for our unknown.

t = 454m / 2m/s = 227s

Answer:

If the lady is traveling 2 meters per second and she travels 454 meters then you will have to divide 454 by 2 to get the amount of time she walked.

454 divided by 2 = 227

This means that the lady traveled for 227 seconds or about 3.78 minutes.

10-kg box is sliding across an ice rink at 10 m/s . A skater exerts a constant force of 10 N against it. How long will it take for the box to come to a complete stop?

Answers

Answer:

Time, t = 10 seconds

Explanation:

Given the following data;

Mass = 10kg

Force = 10N

Final velocity = 10m/s

Initial velocity = 0m/s

To find the time;

First of all, we would find the acceleration of the box.

Force = mass * acceleration

10 = 10 * acceleration

Acceleration = 10/10 = 1m/s²

Now, we can find the time by using the first equation of motion;

V = U + at

10 = 0 + 1t

10 = t

Time, t = 10 seconds

Therefore, it will take 10 seconds for the box to come to a complete stop.

Answers

Answer:

B Eight light-minutes

Explanation:

In the case when the distance separated earth and the sun so here we orbit the sun for a 150 million km distance and the light moves would be 300,000 kilometers per second

Now divide this

= 150 million ÷ 300,000 kilometers per second

= 500 seconds

This 500 seconds represent 8 minutes and 20 seconds

Hence, option B is correct
