Answer:

Consider a satellite with mass Msat orbiting a central body with a mass of mass MCentral. The central body could be a planet, the sun or some other large mass capable of causing sufficient acceleration on a less massive nearby object. If the satellite moves in circular motion, then the net centripetal force acting upon this orbiting satellite is given by the relationship

Fnet = ( Msat • v2 ) / R

Explanation:

The acceleration of the satellite released from a spacecraft orbiting a planet at an altitude of 120 km and the planet has a mass of 5.2 x 10^23 kg and a radius of 2800 km is 4.426 *  [tex]10^6[/tex]  [tex]m/s^2[/tex].

The term "acceleration" refers to the rate and direction at which velocity varies over time. Acceleration is the change in direction or speed of an object or points moving ahead. The frequent change in direction causes motion on a circle to rise even when the speed remains constant.

For all other motions, these effects increase the acceleration. A vector quantity, acceleration, is something that has both a magnitude and a direction. Velocity is a vector quantity as well.

Given:

The altitude of the spacecraft, h = 120 km,

The mass of the planet, m = [tex]5.2 * 10^{23}[/tex] kg,

The radius of the planet, r = 2800 km.

Calculate the acceleration by the formula given below,

A = [tex]G* m /r^2[/tex]

Here, A is the acceleration, G is the gravitational constant,

Substitute the values,

A = 6.674 * [tex]10^{-11}[/tex] *5.2 * [tex]10^{23}[/tex] / [tex]2800^2[/tex]

A = 4.426 *  [tex]10^6[/tex]  [tex]m/s^2[/tex]

Therefore, the acceleration of the satellite is 4.426 *  [tex]10^6[/tex]  [tex]m/s^2[/tex]

Answer:

80 kg weighs 80 kg x 9.8 m/s2 = 784 kg m/s2, or 784 Newtons. The surface gravity of Mercury is 0.39 that of Earth's (table 10-1), so 80 kg weighs 784 N x 0.39 = 306 N.

I hope that helps you

Answer:

You are correct the answer is D

Brainliest will be appreciated thank you!

Explanation:

v=?, u=0, a=?, S=22m.

Using the formula, S=ut+½at²

22={0×5}+(½.a.5²)

22=½.a.5²

a=44/25 = 1.76m/s².

Therefore, net force = work done = ma = 48×1.76 = 84.48N.

therefore, power = work done/time = 84.48/5 = 16.896W.

hope this helps you.

Answer:

Explanation:D

When two atoms bond chemically it is because of the interaction between the valence electrons in each atom because only the valence electrons of an atom are responsible for the chemical activity.

Therefore the correct answer is option D.

A chemical reaction is a process in which one or more substances, also known as reactants are converted to one or more different substances, known as products.

Because only an atom's valence electrons are responsible for the chemical activity and because the quantity of valence electrons indicates an atom's valency,

Valency is a highly important requirement for the chemical reactivity of any element, two atoms connect chemically as a result of their contact.

Thus, the correct answer is option D.

Answer:

air is compress able

since air can be compressed, then the hydraulics will not work as well. It won't be able to push the object or brake the wheels. Since water cannot be compressed, it is able to push something, that's how hydraulics work.

Explanation:

it reduces pressure and essentially makes the process less effective.

Answer:

A

Explanation:

Every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.

Anything which has mass to keep the same when comparing the hardness of the solid and occupies space is known as matter, mainly there are four states of matter solid liquid gases, and plasma.

As given in the problem statement we have to find the true statement from the given options that is true for every atom of an element,

The size of an atom of an element is a very small order of magnitude so it can not be seen with a magnifying glass, therefore, option A is not the correct response.

Thus, every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.

Answer:

An object will not move unless acted upon by an unbalanced force.

Explanation:

Since Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Hope this helps!!

According to Newton's law of motion an object will at a state unless and until a force act upon it. Hence, force is an external agent which change the state of an object.

Newton proposed three laws of motion explaining the motion an object. The first law states that an object will continue at the state of motion or rest unless a force acting on it.

Therefore force is an external agent which acts on a body to change it from the state of rest or motion. Force is directly proportional to the mass of the body. Hence, greater the mass, greater force must be applied to change its state.

The first of motion is called law of inertia, where inertia is the tendency of a body to stay in a state. Therefore, force changes this tendency of an object.

Answer:

Explanation:

To find the height of a ball thrown upwards we can use this formula :

     vf^2 = vi^2 + 2ad

     0^2 = 22^2 + 2(-9.8)d

     484 = 19.6d

     24.69 = d

     25 m = d

To find the time of the phone dropped we can use this formula :

     t = √2d/g

     t = √2(15) / 9.8

     t = √30/9.8

     t =√3.142857

     t = 1.749

    t = 1.7 seconds

For a) since this object is free falling we know that it will accelerate towards earth at a rate of 9.8 m/s^2. The slope of a velocity time graph gives us the acceleration of the object. So in this case the slope would be 9.8 m.s^2

Hope this helps!

Constant acceleration of plane = 3m/s²

a) Speed of the plane after 4s

Acceleration = speed/time

3m/s² = speed/4s

S = 12m/s

The speed of the plane after 4s is 12m/s.

b) Flight point will be termed as the point the plane got initial speed, u, 20m/s

Find speed after 8s, v

a = 3m/s²

from,

a = v - u

t

3 = v - 20

8

24 = v - 20

v = 44m/s

After 8s the plane would've 44m/s speed.
