If Kevin with mass 45kg pushes Kisha with a force of 54N, the magnitude of Kevin's acceleration is 1.2 m/s²

Kisha's mass = 60 kg

Kevin's mass = 45 kg

Kevin pushes off Kisha with a force of 54 N

Since it was Kevin that pushed Kisha, and the required force is 54N, we can look for Kevin's acceleration using the equation below

F  =  ma

The considered mass is Kevin's mass

54   =  45a

a   =   54/45

a   =    1.2 m/s²

The magnitude of Kevin's acceleration is 1.2 m/s²

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.

Answer:

Pressure =Area × height

0.01N/cm=300cm×height

height=0.01×300

3cm

The weight of the book is equal to 3N.

Pressure can be described as the ratio of the force exerted to the surface area over which the force is exerted. We can define pressure as the force applied perpendicular to the surface per unit area over which that applied force is distributed.

The SI unit of pressure can be represented as the pascal (Pa). A pascal is the force of one newton (N) exerted over a surface area of 1 m². Since the pressure is dependent on the area so the pressure can be increased and decreased without changing the force.

Given, the pressure on the book, P = 0.01 N/cm²

The area of the book, A = 300 cm²

Pressure = Force/ Area

Force = Pressure ×Area

Force = 0.01  × 300 = 3 N

Weight of the book, W = mg = 3 N

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:

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:

Below

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!

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:

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.
