When the white ball strikes the other colored balls, what can you say about the total momentum of all of the balls combined?

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is  B

Explanation:

From the question we are told that

  The terminal  velocity of both balls is  [tex]v_t  =  32 \ m/s[/tex]

   The speed with which ball A is thrown up at t =0 s is  [tex]v__A}}  =  16\sqrt{2}[/tex]

   The speed with which ball B is thrown 30° below the horizontal  at t =0 s is  

[tex]v__{B}} =  32\sqrt{2}[/tex]

Generally the acceleration of ball A is (g i.e acceleration due gravity)given that it is thrown straight up  

Generally the vertical  acceleration of ball B is mathematically represented as

    [tex]a  = gcos (90 - 30)[/tex]

      [tex]a  = gcos (60)[/tex]

Generally the ratio of both acceleration is  

     [tex]\frac{a__{{A}}}{a__{{B}}}} =\frac{g}{gsin(60)}[/tex]

=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{sin (60)}[/tex]

=>  [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{\frac{\sqrt{3} }{2} }[/tex]

=>[tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} }[/tex]

Rationalizing

=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} } *\frac{\sqrt{3} }{\sqrt{3} }[/tex]

=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2 \sqrt{3} }{3}[/tex]

=>[tex]a__{B}} = \frac{2\sqrt{3} }{3} * a__{A}}[/tex]

Answer:

Gravitational pulls things to the ground

Elastic is stretched or compressed or a shape or object

Kinetic is kinda like the force of motion

Hope this helps

In the gravitational energy, things are pulled to the ground by gravity, for elastic energy stretched, squeezed, or as a shape or item, and for kinetic energy it is similar to the force of motion.

Kinetic energy is the term used in mechanics to describe the impulse that an object experiences as it moves. It is described as the amount of effort needed to move someone of a certain mass to rest to a given velocity. Except for fluctuations in speed, the body retains its acceleration after receiving it during acceleration.

The body uses the same lot of fuel when slowing down from its current rate to a state of rest. Formally, kinetic energy refers to any element in the Lagrangian of such a system that seems to have a derivative with respect to time.

Explanation:

The factor that is most likely to be responsible for the changes observed in the world's rainforest is human activities.

There has been a surge in the human population leading to an increased need for housing, foods, and other infrastructures. All these needs are directly or indirectly provided by the forest. Hence, the more the population of human expands, the more pressure that would be exerted on the rainforest and, indeed, other forests of the world.

The correct option is b.

Answer:

C) he had more power running than walking

Explanation:

saw it on a quizlet. not 100% sure tho

Hiro walks up a flight of stairs in his apartment building. Later in the day, he runs up the same flight of stairs so He had more power running than walking.

In physics, power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.

Power is related to other quantities; for example, the power involved in moving a ground vehicle is the product of the traction force on the wheels and the velocity of the vehicle.

The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft

Since we know that Hiro will run on stairs to minimize the time of reaching his home so if time decreases then he has to increase his power as power is the ratio of work and time.

Hence Hiro walks up a flight of stairs in his apartment building. Later in the day, he runs up the same flight of stairs so He had more power running than walking.

Answer:

Low pressure

Explanation:

Take two nearby points at the junction of both the tube, let point 1 be in the air tube while point 2 be in the paint tube.

According to Bernoulli's principle, the air at point 1 is moving with some speed which causes the pressure drop inside tube 1, while at point 2 there is no velocity, so there is no pressure drop at that point. In fact, the pressure at point 2 approximately equals the atmospheric pressure.

As both the points are taken is nearby at the junction, to the pressure drop in the flow air pipe causes the suction of fluid from the relatively high-pressure tube (paint tube).

Hence, this rush of air creates low pressure, which sucks the paint up the tube and into the stream of air.

Answer: The answer to 3 to is less inertia. The answer to 4 is large amount of inertia. The answer to 5 is large amount of inertia. The answer to 6 is more fuel. Number 6 is kind of unkown considering I can’t see the other answer but I guess it’s more fuel.

Explanation: Inertia is the resistance of the object to any change in its motion, including a change in direction. An object will stay still or keep moving at the same speed and in a straight line, unless it is acted upon by an external unbalanced force. So when there is more inertia, it’s harder to control, but when it has less inertia, it’s more loose and easier to move around.

Answer:

F=-100N; a=1.3m/s^2

Explanation:

Force is being made by student, so wall counteracts that force by not moving so it is equally opposite.

The force of the wall pushing back on the student would be 100 Newtons, and the acceleration of the student as she moves away from the wall would be 1.33 m/s²

Newton's third law of motion state that for every action force there exists a complementary reaction force that balances it.

As given in the problem a student is on a skateboard facing a wall. The student and skateboard have a mass of 75 kilograms. The student pushes off of the wall with a force of 100 Newtons,

The force of the wall pushing back the student = 100 Newtons

The acceleration of the student = 100/75

                                                     =1.33 m/s²

Thus, The student would be pushed back against the wall by a force of 100 Newtons, and she would accelerate away from the wall at a rate of 1.33 m/s².

Answer:

m=0,  λ₀  = 522 10⁻⁹ m

Explanation:

In this case we can see that the first boy M The reflected light suffers an interference phenomenon, let's analyze what happens on each surface

* When light passes from a medium with a lower refractive index to a medium with a higher refractive index, it undergoes a phase change of pi rad (180º).

  This occurs when passing from air to oil, but not at the oil-water interface.

* within the material the wavelength changes by the refractive index

        λₙ = λ₀ / n

therefore introducing this into the constructive interference equation and assuming almost perpendicular incidence remains

         2 t = (m + ½) λₙ

         2t = (m + ½) λ₀ / n

        λ₀ = 2t n / (m + ½)

light in the first order (m = 1)

       λ₀  = 2 90 10⁻⁹ 1.45 / (1+ ½)

       λ₀  = 174 10⁻⁹ m

the light for zero order (m = 0)

         λ₀ = 2 90 10⁻⁹ 1.45 / (0+ ½)

         λ₀  = 522 10⁻⁹ m

Answer:

Antibacterial activity

Explanation:

The antibacterial property does not allow bacterias to live in an environment. Many spices have the ability to show antibacterial activity, few of these spices can be named as cinnamon, turmeric, or clove. Because they have antimicrobial or antibacterial characteristics that is why they are used for food preservation, disease prevention, and provide many health benefits. But, not every spice has antibacterial characteristics, that is why Janel experimented with five different spices to see which amongst them possess antibacterial characteristics.

Hence the correct answer is Antibacterial activity.

Hey there!

Given;

F = 10N

Mass = 5kg

Acceleration due to gravity (a)= 9.8m/s^2

We know that;

F = m*a

Put all values and solve for "m".

10 = m*9.8

Simplify it.

[tex]m = \frac{10}{9.8} [/tex]

Therefore, m= 1.0204kg.
