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.

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.

Given :

The pink car has a velocity of 4.4 m/s to the right while the blue car has a velocity of 6.8 m/s to the left.

To Find :

If the two cars crashed and stuck together, what would their combined momentum be afterwards and what direction would they be moving.

Solution :

Let, combined velocity of the car is v.

Also, let us assume that mass of both the cars are equal and it is m.

By conservation of momentum :

Initial momentum = Final momentum

 m( 6.8 ) - m( 4.4 ) = 2mv

2mv =2.4m

v = 1.2 m/s

Therefore, the velocity of combined car after crash is 1.2 m/s .

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

Substituting,

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)

   = 4862635.79 + 3610.32

   = [tex]$4.8 \times 10^6 \ N$[/tex]

Therefore thrust of the jet engine is [tex]$4.8 \times 10^6 \ N$[/tex].

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.

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.

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.

Answer:

[tex]a=32\ m/s^2[/tex]

Explanation:

Given that,

The velocity of an astronaut in a circular path, v = 16 m/s

The radius of the accelerator, r = 8 m

We need to find his centripetal acceleration. The formula that is used to find the centripetal acceleration is given by :

[tex]a=\dfrac{v^2}{r}\\\\a=\dfrac{(16)^2}{8}\\\\a=32\ m/s^2[/tex]

So, the required centripetal acceleration is [tex]32\ m/s^2[/tex].

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

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]

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]

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

[tex]\mathbf{d_i = }[/tex] -54.12  cm

Answer:

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,

Explanation:

Newton explained that all objects attract each other, as the Earth is much greater than the apple, it is this that falls towards the Earth.

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

     [tex]a_{c} = g[/tex]

This principle is used in all circular motion devices, for example the merry-go-round in parks, the radius of the circle is proportional to the speed of the turn and therefore to the centripetal acceleration of the device.

Kinetic energy refers to the form of energy that's used by an object due to its motion.

You didn't give more information about the values, therefore, the kinetic energy will be explained. It should be noted that when work, which helps in the transfer of energy is done on an object, the object will speed up and thereby gain kinetic energy.

Kinetic energy simply refers to the property of a moving object or a particle. It depends on both motion and mass. The formula for the calculation of kinetic energy is given as:= 1/2mv²
