what is Newton's second law it's challenging question
let's observ who is answering first​

Answers

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Answer:

second law is f=ma (force=massxacceleration)

Explanation:

A book of a mass 0.5kg is dropped from a height of 2.8m. How much mechanical energy does it have right before it hits the ground? (Assume there is no air resistance.) Acceleration due to gravity is g= 9.8 m/s^2.

Answers

Answer:

13.7 J

Explanation:

In absence of air resistance, the mechanical energy of the object is conserved during the fall: this means that the initial gravitational potential energy that it has at the beginning of the fall will be entirely converted into kinetic energy when the book is just about the hit the ground.

Therefore, this also means that we can calculate the mechanical energy at the beginning of the fall, as this will be equal to the mechanical energy just before the book hits the ground.

At the beginning of the fall, the mechanical energy is all gravitational potential energy:

where

m = 0.5 kg is the mass of the book

is the acceleration of gravity

h = 2.8 m is the height above the ground

it takes 5100 N of force to accelerate a ford mustang 3 m/s2 what is the mass of the car

Answers

Answer:

1700 kg

Explanation:

The mass of the ford mustang car be 1700 kg.

What is mass?

In physics, mass is a quantitative measurement of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force.

The change caused by an applied force is smaller the more mass a body has. The kilograms serves as the unit of mass in the International System of Units (SI).

Given parameters:

Force applied on the ford mustang car: F = 5100 N.

Acceleration of the ford mustang car: a = 3 m/s^2.

So, The mass of the ford mustang car be = force/acceleration

= 5100/3 kg.

= 1700 kg.

Hence, the mass of the ford mustang car be  1700 kg.

A jet aircraft is traveling at 214 m/s in hor-

izontal flight. The engine takes in air at a

rate of 115 kg/s and burns fuel at a rate of

2.53 kg/s. The exhaust gases are ejected at

276 m/s relative to the aircraft.

Find the thrust of the jet engine.

Answer in units of N.

Answers

Answer:

The thrust is  [tex]F = 7828.3 \  N [/tex]

Explanation:

From the question we are told that

   The speed of the jet aircraft is  [tex]v = 214 \ m/s[/tex]

    The rate at which the engine takes in air is [tex]\^ Q = 115 \ kg/s[/tex]

    The rate  at which the engine burns fuel is  [tex]\r m = 2.53 \ kg/s[/tex]

    The speed of the exhaust gases is  [tex]u = 276 \ m/s[/tex]

   

Generally the thrust of the engine is mathematically represented as

      [tex]F =[ \^ Q * ( u - v )] + (\r m * u)[/tex]

=>   [tex]F =[ 115 * ( 276  -  214 )]  + (2.53 * 276)[/tex]

=>   [tex]F = 7828.3 \  N [/tex]

A 0.50-kg ball is thrown vertically upward with an initial velocity of 35 m/s. Approximately, how high will the ball rise?

Answers

Answer:

62.5m

Explanation:

Given parameters:

Mass of the ball  = 0.5kg

Initial velocity  = 35m/s

At the maximum height final velocity is 0m/s

Unknown:

Height of the rise of the ball = ?

Solution:

To solve this problem, we apply the right motion equation which is shown below;

           v²  = u² - 2gh

v is the final velocity

u is the initial velocity

g is the acceleration due to gravity

h is the height

Now insert the parameters and solve;

          0² = 35² - 2(9.8)(h)

      -1225 = -19.6h

           h = 62.5m

HELP ASAP!!!! Ashley and Rachel are driving bumper cars. Ashley's bumper car is moving and she collides with Rachel bumper car, which is not moving. Describe what happens to the momentum of both cars During this collision.

Answers

Answer:

Rachels car moves and ashleys stops

Explanation:

When Ashley's moving car collides with Rachel's bumper car which is at rest then some of the momentum of Ashley's car is transferred to Rachel's car causing it to move.

What is the conservation of momentum?

Conservation of momentum states that the momentum of a system is constant if there is the absence of external forces on the system. The momentum of an object can be conserved and is a vector quantity.

Momentum can be defined as the multiplication of the mass of a particle and its velocity. The law of conservation of momentum is confirmed by experiment and can be deduced mathematically on the presumption that space is uniform.

Conservation of linear momentum is derived from Newton’s second law of motion states that the total momentum remains the same in an isolated system.

The total momentum of  Ashley's car and Rachel's car remains conserved. After the collision, the momentum transferred from  Ashley's car and Rachel's car which makes it move.

Where does the fish appear to be when it is 38.9 cm from the front surface of the bowl? (Give your answer in cm.)


______ cm

Answers

Answer:

Explanation:

From the information given:

We can properly determine the distance where the fish appear in the air viewing it from in front of the bowl by using the formula:

[tex]\dfrac{n_i}{d_o}+\dfrac{n_2}{d_1}= \dfrac{n_2-n_1}{r}[/tex]

where;

[tex]n_1[/tex] = refractive index in the air;  = 1.33  &

[tex]n_2[/tex] = refractive index in water. = 1

[tex]\dfrac{n_2}{d_i}= \dfrac{n_2-n_1}{r}-\dfrac{n_1}{d_o}[/tex]

[tex]\dfrac{1}{d_i}= \dfrac{1-1.33}{-21 \ cm}-\dfrac{1.33}{4.7\ cm}[/tex]

[tex]\dfrac{1}{d_i}= - 0.26726 \ cm[/tex]

[tex]d_i =\dfrac{1}{ - 0.26726 \ cm}[/tex]

[tex]\mathbf{d_i }[/tex] = - 3.74 cm

2)

To determine where the fish appear to be when it is  38.9 cm from the front surface of the bowl by using the formula:

[tex]\dfrac{n_2}{d_i}= \dfrac{n_2-n_1}{r}-\dfrac{n_1}{d_o}[/tex]

[tex]\dfrac{1}{d_i}= \dfrac{1-1.33}{-21 \ cm}-\dfrac{1.33}{38.9\ cm}[/tex]

[tex]\dfrac{1}{d_i}=- 0.0184759 \ cm[/tex]

Answers

Answer:

I am pretty sure it is A!

:D

The air is warmer near Earth's surface because warm air is denser and sits on top of the Earth's surface. The correct option is B.

What is air density?

The mass of the air per unit volume is known as the air density. Its unit is kg/m³.

Due to the lower pressures in the air above, air expands when it rises. cooling air expands.

The hottest temperatures in the troposphere are often found at the earth's surface because the sun heats the atmosphere predominantly from the surface and because the air cools as it ascends.

Because warm air is denser and lies on top of the surface of the Earth, it is warmer near the surface of the earth.

Hence, the correct option is B.

rate of 85.9 kg/s and burns fuel at a rate of

3.92 kg/s. The exhaust gases are ejected at

921 m/s relative to the aircraft.

Find the thrust of the jet engine.

Answers

Solution :

Speed of the air craft, [tex]$S_a$[/tex] = 262 m/s

Fuel burns at the rate of, [tex]$S_b$[/tex] = 3.92 kg/s

Rate at which the engine takes in air, [tex]$S_{air}$[/tex] = 85.9 kg/s

Speed of the exhaust gas that are ejected relative to the aircraft, [tex]$S_{exh}$[/tex] =921 m/s

Therefore, the upward thrust of the jet engine is given by

[tex]$F=S_{air}(S_{exh}-S_a)+(S_b \times S_{exh})$[/tex]

F = 85.9(921 - 262) + (3.92 x 921)

Which type of electromagnetic waves make up the colors of a rainbow seen after a storm?

A. visible light
B. infrared light
C. X-rays
D. ultraviolet light

Answers

Answer:

we conclude that visible light is that electromagnetic wave that makes up the colors of a rainbow seen after a storm.

Hence, option A is correct.

Explanation:

Generally, after the storm, we can witness the presence of a rainbow with our naked eyes. Rainbow, visible to our eyes, consists of all the seven constituent colors of white light. Those seven colors range from violet to red, all having different wavelengths. When water particles present in our atmosphere get exposed to light, all the constituent colors of a white light tend to deviate at a variety of angles. It happens due to their refraction through water particles; thus, a spectrum is obtained.

As we cannot see X-rays, UV rays, and infrared waves through our naked eye, visible light is the kind of electromagnetic wave that makes anyone able to see the objects.  

Please note that all the constitute colors of a beautiful rainbow associate with the visible region of the electromagnetic spectrum.

Therefore, we conclude that visible light is that electromagnetic wave that makes up the colors of a rainbow seen after a storm.

Hence, option A is correct.

The moon also falls towards the Earth, but having a tangential speed, the acceleration it has is used in the change of direction of its speed, in general this acceleration is called centripetal
