Por una tuberia de 2.65 cm de diámetro fluye agua con una velocidad de 5 m/s; en una parte de la
tuberia hay una reducción en su diámetro de 0.65 cm. ¿Qué velocidad llevará el agua en este punto?

Answers

Answer 1

La ecuación de continuidad podemos encontrar el resultado para la velocidad de fluido en la reducción de la tubería es:

       v = 83,1 m/s

La mecánica de fluidos estudia el movimiento de líquidos y gases por diferentes sistemas, la conservación de la masa  es escrita como la ecuación de continuidad

            A₁ v₁ = A₂ v₂

Donde  los subíndices son en dos puntos de interés, A el área de la tubería y v la velocidad del fluido.

Indican la velocidad de fluido es v₁ = 5 m/s y el diámetro de la tubería es d₁= 2,65 cm, piden encontrar la velocidad en la parte con un diámetro de d₂ = 0,65 cm

El área de la tubería es

         A = [tex]\pi ^r^2 = \pi \frac{d^2}{4}[/tex]  

         [tex]v_2 =\frac{A_1}{A_2} \ v_1 \\v_2 = ( \frac{d_1}{d_2} )^2 \ v_1[/tex]  

Calculemos

       v₂ =  [tex]( \frac{2.65}{0.65} )^2 \ 5[/tex]  

       v₂ =  83,1 m/s

En conclusión usando la ecuación de continuidad podemos encontrar el resultado para la velocidad de fluido en la reducción de la tubería es:

      v = 83,1 m/s

An object if mass 30 kg is falling in air and experiences a force due to air resistance of 50 newtons.​

Answers

Hi there!

On the object, we know that there are two forces working on the object:

-Force due to gravity (Mg)

-Force due to air resistance

Let the positive direction of the force be downwards (direction of the acceleration)

We can write the summation of forces as:

∑F = Mg - Fa

Plug in values. Let g ≈ 10 m/s²

∑F = 30(10) - 50 = 250N

Find the acceleration using the formula:

∑F = m · a

∑F/m = a

Plug in values:

250/30 = 8.33 m/s²

One train (22,680 kg) moving east at 170 km/h collides with a car (1,200 kg) that was moving north at 5 km/h. They get attached to each other, moving in the direction of the train. What is the final velocity of the objects and the type of collision? If the collision happened in 1.2X10-3 seconds, what was the force? How much kinetic energy was lost?

Answers

The final velocity of the objects is 229.82km/hrSince energy was lost after the collision, the type of collision that occurs is an elastic collision.The required force is 1,090,918,000NThe amount of Kinetic energy lost is 12,401,976.656Joules

According to the law of collision'

m1u1 + m2u2 = (m1+m2)v

Given the following:

m1 = 22,680kg

u1 =170km/h

m2 = 1200kg

u2 = 5km/hr

Get the final velocity "v"

22680(170) + 1200(5) = (22680 + 1200)v

3855600 + 6000 = 12880v

3,861,600 = 12880v

v = 3,861,600/12,880

v = 229.82km/hr

Hence the final velocity of the objects is 229.82km/hr

Since energy was lost after the collision, the type of collision that occurs is an elastic collision.

According to Newton's second law, the formula for calculating the force is expressed as;

F = ma

F = m(v-u)/t

F = 22680+1200(229.82-175)/t

Ft = 23880(54.82)

F = 1,309,101.6/0.0012

F = 1,090,918,000N

Hence the required force is 1,090,918,000N

KE lost = Kinetic energy after collision - Kinetic energy before collision

Kinetic energy after collision = 1/2 * 12880 * 229.82²

Kinetic energy after collision = 340,142,976.656 Jolues

Kinetic energy before collision = 1/2 * 22680(170)²+ 1/2*1200(5)²

Kinetic energy before collision = 327,726,000 + 15000

Kinetic energy before collision = 327,741,000

Kinetic energy lost = 340,142,976.656 - 327,741,000 =  12,401,976.656Joules

If a 2 kg block of aluminium (SHC: 921 J/kg°C) is heated from 20°C to 40°C, how much energy was transferred to it?

Answers

H = mc∆T

where, H=heat energy

c = SHC

H = 2*921*(40-20)

H = 36840J

H = 36.84KJ

The energy transferred to it is 36.84KJ

The energy transferred to aluminum from 20°C to 40 °C is equal to 36840 J.

What is the specific heat capacity?

The specific heat capacity can be described as the quantity of heat required to increase the temperature of 1 unit of substance by one degree Celsius. The specific heat capacity of the substance depends upon the nature of the substance.

The mathematical equation is used to calculate the specific heat is equal to:

[tex]Q = m\times C\times \triangle T[/tex]

Given, the mass of the aluminum block, m = 2 Kg

The initial temperature of aluminum, T₁ = 20 °C

The final temperature of the aluminum, T₂ = 40 °C

The specific heat capacity of aluminum, C = 921 J/kg°C

The energy transferred to the aluminum block:

Q = 2 × 921 × (40-20)

Q = 36840 J

Therefore, the energy transferred to aluminum from 20°C to 40°C is  36840 J.

21) A charged polyester ball is placed over a charged PVC pipe. The ball, which
has a mass of 1.2 grams, rests 42 cm above the pipe. If the ball and pipe have
the same negative charge, what is the charge on the ball?

Answers

The negative charge on the polyester ball is -1.53 x 10⁻⁶ C.

The given parameters;

Pls tell the ans of this asap (ncert hindi class 8 kamchor chp) adapted from A Fableby Mark Twain1 An artist who had painted a small and very beautiful picture placed it so that he could see it in the mirror. He said, This doubles the distance and softens it, and it is twice as lovely as it was before. The animals out in the woods heard of this through the housecat, who was greatly admired by them because he was so learned, and so refined and civilized, and so polite and highbred, and could tell them so much which they didnt know before, and were not certain about afterward. They were much excited about this new piece of gossip, and they asked questions, so as to get at a full understanding of it. They asked what a picture was, and the cat explained.2 It is a flat thing, he said; wonderfully flat, marvelously flat, enchantingly flat and elegant. And, oh, so beautiful!3 That excited them almost to a frenzy, and they said they would give the world to see it.4 Then the bear asked, What is it that makes it so beautiful?5 It is the looks of it, said the cat.6 This filled them with admiration and uncertainty, and they were more excited than ever.7 Then the cow asked, What is a mirror?8 It is a hole in the wall, said the cat. You look in it, and there you see the picture, and it is so dainty and charming and ethereal1 and inspiring in its unimaginable beauty that your head turns round and round, and you almost swoon with delight.9 The donkey had not said anything as yet; he now began to throw doubts. He said there had never been anything as beautiful as this before, and probably wasnt now. He said that when it took a whole basketful of sesquipedalian2 adjectives to whoop up a thing of beauty, it was time for suspicion.10 It was easy to see that these doubts were having an effect upon the animals, so the cat went off offended. The subject was dropped for a couple of days, but in the meantime curiosity was taking a fresh start, and there was a revival of interest perceptible. Then the animals assailed the donkey for spoiling what could possibly have been a pleasure to them, on a mere suspicion that the picture was not beautiful, without any evidence that such was the case. The donkey was not troubled; he was calm, and said there was one way to find out who was in the right, himself or the cat: he would go and look in that hole, and come back and tell what he found there. The animals felt relieved and grateful, and asked him to go at oncewhich he did.11 But he did not know where he ought to stand; and so, through error, he stood between the picture and the mirror. The result was that the picture had no chance, and didnt show up.12 He returned home and said, The cat lied. There was nothing in that hole but a donkey. There wasnt a sign of a flat thing visible. It was a handsome donkey, and friendly, but just a donkey, and nothing more.13 The elephant asked, Did you see it good and clear? Were you close to it?14 I saw it good and clear, O Hathi, King of Beasts. I was so close that I touched noses with it.15 This is very strange, said the elephant; the cat was always truthful beforeas far as we could make out. Let another witness try. Go, Baloo, look in the hole, and come and report.16 So the bear went. When he came back, he said, Both the cat and the donkey have lied; there was nothing in the hole but a bear.17 Great was the surprise and puzzlement of the animals. Each was now anxious to make the test himself and get at the straight truth. The elephant sent them one at a time.18 First, the cow. She found nothing in the hole but a cow.19 The tiger found nothing in it but a tiger.20 The lion found nothing in it but a lion.21 The leopard found nothing in it but a leopard.22 The camel found a camel, and nothing more.23 Then Hathi was wroth,3 and said he would have the truth, if he had to go and fetch it himself. When he returned, he abused his whole subjectry for liars, and was in an unappeasable fury with the moral and mental blindness of the cat. He said that anybody but a nearsighted fool could see that there was nothing in the hole but an elephant.MORAL, BY THE CAT24 You can find in a text whatever you bring, if you will stand between it and the mirror of your imagination.Which statement about the elephant is most supported by the events in the passage?A.He is easily angered.B.He does not trust the cat.C.He has problems with his eyes.D.He is the leader of the animals.
