<u>Acceleration = 4 m/s² </u>

Step-by-step explanation:-

Let's solve this question easily...

Given,

Initial velocity (u) = 3 m/s

Final velocity (v) = 5 m/s

Displacement (s) = 2m

Using the formula,

\frac{ {v}^{2} -  {u}^{2}  }{2as}

So, in order to get the value of a, let's do:

a =  \frac{ {v}^{2} -  {u}^{2}  }{2s}

Now substitute all the given values. So,

a =  \frac{ {5}^{2} -  {3}^{2}  }{2 \ \times 2}

a =  \frac{25 - 9}{4}

a =  \frac{16}{4}

a = 4 \: m / {s}^{2}

Note:- You can also write the answer as:

4 \: m. {s}^{ - 2}

Therefore, the answer is <u>4</u><u> </u><u>m</u><u>/</u><u>s²</u> or <u>4 m.s^-2</u>

Why is a cathode ray tube connected to a vacuum pump?
seropon [69]
If the cathode ray tube is not evacuated, the electrons emitted collide with the air molecules and cannot reach the screen effectively. Therefore, the CRT is connected to a vacuum pump to remove air.

Two students are relaxing in their dorm room and are too lazy to get up and shut the door. One of the students suggests throwing
Anna11 [10]

Answer:

The collision of the hard baseball that bounces back will shut the door fastest.

Explanation:

Let the mass of the door be M

The mass of the hard baseball and soft clay Is m

Let the initial velocity of both the hard baseball and the soft clay be v₀

Let the Final velocity of the hard baseball be v₁

Then let the final velocity of the door be v

Using the law of conservation of Momentum,

Momentum before collision = Momentum after collision

For the hard baseball system

Momentum before collision = (m)(v₀) + (M)(0) = mv₀ (the initial velocity of the door is 0 m/s since it is at rest)

Momentum after collision = (m)(-v₁) + (M)(v)

= (-mv₁ + Mv) (the velocity of the hard baseball after collision has a minus sign because it is in the opposite direction to the initial velocity)

mv₀ = (-mv₁ + Mv)

Mv = mv₀ + mv₁ = m(v₀ + v₁)

v = m(v₀ + v₁)/M

For the soft clay,

Momentum before collision = (m)(v₀) + (M)(0) = mv₀

Momentum after collision = (m + M)(v)

mv₀ = (m + M) v

v = mv₀/(m + M)

Comparing these two answers for the velocity of the door after collision

With hard baseball that bounces back

v = m(v₀ + v₁)/M

With soft clay that sticks to the door

v = mv₀/(m + M)

v for hard baseball has a bigger numerator and a smaller denominator, hence, it has the higher value and this means the door will close faster with a numerically higher final velocity from the elastic collision of the hard baseball with the door.

Hope this Helps!!!

OF BRICK<br> (a)<br> The pushing force does not make the brick move. Explain why.
Sever21 [200]

Every force has an equal but opposite reaction, the forces are balanced out on the brick.

Weight (mg) acts downwards from the brick but the normal contact force from the table is acting upwards therefore resultant force is 0N equilibrium

You know the direction of the force is based upon the resultant force, so if you were to push the brick horizontally across the table it would travel horizontally

andriy [413]

Answer:

%Open the file.

fID = fopen('parts_inv.dat');

%Read from the file.

data = fscanf(fID,'%d\t%f\t%d',[3,inf]);

%Close

fclose(fID);

%Restore the data.

data = data';

%Get the size

[rs, cs] = size(data);

%Set value.

invCost = 0;

%Loop

for rw = 1 : rs

%Find cost

invCost = invCost + (data(rw, 2) * data(rw, 3));

%Loop end

end

%Display the cost.

Suppose that a sound source is emitting waves uniformly in all directions. If you move to a point twice as far away from the sou
Helen [10]

Answer:

<em>d. unchanged.</em>

Explanation:

The frequency of a wave is dependent on the speed of the wave and the wavelength of the wave. The frequency is characteristic for a wave, and does not change with distance. This is unlike the amplitude which determines the intensity, which decreases with distance.

In a wave, the velocity of propagation of a wave is the product of its wavelength and its frequency. The speed of sound does not change with distance, except when entering from one medium to another, and we can see from

v = fλ

that the frequency is tied to the wave, and does not change throughout the waveform.

where v is the speed of the sound wave

f is the frequency

λ is the wavelength of the sound wave.
