Answers

Answer:

force of attraction will be increased by 9

Explanation:

force of attraction is inversely proportional to square of distance

i.e F= 1/

F=1/3R²

F=1/9R

multiply both side by 9

9×F= 9×1/9R

9F= 1/R

Can air make shadows?

Answers

Answer:

Yes, air can indeed make shadows. A shadow occurs when an object in a light beam prevents some of the light from continuing on in the forward direction. When the light beam hits a wall or the ground, a darker shape is visible where less light is hitting the surface. Refraction is responsible.

A 20 N force pulls to the right and friction pulls 5 N. If the mass is 5 kg, find acceleration.​

Answers

Answer:

Explanation:

Force - frictional Force = m * a

20N - 5N = 5 * a

15N = 5*a

15N / 5 = a

a = 3 m/s^2

You should note a couple of things.

1. The frictional Force always opposes the direction of motion. In this case it is minus and the 20 N is plus. It makes the acceleration less. If the friction force was not there then 20 N = m * a

20N = 5 kg * a

a = 20/5

a = 4 m/s^2.

A 10 kg box initially at rest accelerates uniformly to a speed of 20 m/s in 2 seconds. Determine the A. energy gained by the block, B. Power developed by the box at the end of 10 seconds.​

Answers

Answer:

20 40

Explanation:

A 10 kg box initially at rest accelerates uniformly to a speed of 20 m/s in 2 seconds, energy gained by the block 2000 J and Power developed by the box at the end of 10 seconds 5000 Watt

What is work done?

The total amount of energy transferred when a force is applied to move an object through some distance

The work done is the multiplication of applied force with displacement.

Work Done = Force * Displacement

As given in the problem A 10 kg box initially at rest accelerates uniformly to a speed of 20 m/s in 2 seconds

By using the first equation of motion

v = u + at

20 = 0 + 2a

a = 10 m/s²

By using the third equation of motion

v² - u² = 2as

20² - 0² = 2×10×s

s = 400/20

s = 20 m

Force = ma

          = 10 ×10

          = 100 N

work done = Force × displacement

                   = 100 ×20

                   = 2000 J

Velocity after 10 seconds

V= u + at

  = 0 + 10×10

  = 100 m/s

work done after 10 seconds

= 1/2mv²

= 0.5×10×10²

=50000 J

Power = work done  / time

           = 50000/10

           = 5000 Watt

Thus, energy gained by the block 2000 J and Power developed by the box at the end of 10 seconds 5000 Watt

find the tension in each vertical string

Answers

Answer:

Fp = 36 N

Fq = 58 N

Explanation:

Let the left end be the reference end with string p closest to it.

Let CCW moments be positive

Sum moments about p to zero

1(9.8)[2 - 1] + Fq[6 - 2] - 5(9.8)[8/2 - 2] - 1.5(9.8)[5 - 2] - 2(9.8)[7 - 2] = 0

                                                                              Fq[4] = 23.5(9.8)

                                                                                  Fq = 57.575 ≈ 58 N

Sum moments about q to zero

1(9.8)[6 - 1]  - Fp[6 - 2] + 5(9.8)[6 - 8/2] + 1.5(9.8)[6 - 5] - 2(9.8)[7 - 6] = 0

                                                                                                     Fp = 35.525 N

or

Sum vertical forces to zero

Fp + 57.575 - (9.8)(1 + 1.5 + 2 + 5) = 0

Fp = 35.525  ≈ 36 N

v = 2gR (use conservation of energy)
(b) Show that the snowboarder's centripetal acceleration at the bottom is
ac = 2g (Apply the expression for centripetal acceleration)
(c) Show that the normal force on the snowboarder at the bottom of the halfpipe has a magnitude of 3mg (Use Newton's second law of motion)

Answers

A snowboarder drops from rest into a halfpipe of radius R and slides down its frictionless surface to the bottom, the snowboarder's speed is [tex]\mathbf{v = \sqrt{2gR}}[/tex]

The snowboarder's centripetal acceleration at the bottom is [tex]\mathbf{a_c = 2g}[/tex]. The normal force acting on the snowboarder at the bottom of the halfpipe = 3mg

According to the conservation of energy, at any given point of motion, the energy of a system will always be constant.

Using the conservation of energy at rest and also at the bottom of the pipe.

Total potential energy of the person(since its at rest = Total kinetic energy at the bottom of the pipe.

[tex]\mathbf{mgR = \dfrac{1}{2}mv^2}[/tex]

The objective is to make the velocity (v) the subject of the formula:

[tex]\mathbf{gR = \dfrac{1}{2}v^2}[/tex]

[tex]\mathbf{2gR = v^2}[/tex]

[tex]\mathbf{v = \sqrt{2gR}}[/tex]

(b)

Using the expression for centripetal acceleration;

[tex]\mathbf{a_c = \dfrac{v^2}{R}}[/tex]

here,

let's replace [tex]\mathbf{v \ \ \ with \ \ \sqrt{2gR}}[/tex];

Then;

[tex]\mathbf{a_c = \dfrac{(\sqrt{2gR})^2}{R}}[/tex]

[tex]\mathbf{a_c =2g}[/tex]

From the image attached below;

Provided that:

n = normal forcew = mg  weight of the person[tex]\mathbf{F_c}[/tex] = centripetal force

Then, we can infer that the normal net force acting on the person can be computed as:

[tex]\mathbf{F_c = n -mg}[/tex]

By rearrangement;

[tex]\mathbf{n =F_c +mg}[/tex]

where;

[tex]\mathbf{F_c = 2 mg}[/tex]

n = 2mg + mg

n = 3mg

Therefore, we can conclude that the snowboarder's speed, centripetal force, and normal force are proved.

You have given us a very weird question. Things do not mesh

If the mass is 500 kg and sits 25 m above the lowest spot on the track, the potential energy is

PE  = mgh = 500(9.8)(25) = 122500 Joules,

not the reported 61250 Joules

So either the Joules is incorrect or the mass is supposed to be 250 kg.

In either case, in the absence of friction, the potential energy will convert to kinetic energy.

½mv² = mgh

     v = √2gh

which does not involve the use of either Joules or kilograms.

Maximum velocity when starting from rest is

v = √(2(9.8)25) = √490 = 22.135943...

A .Not enough information
B. Ball B would hit the ground first
C. Ball A and B will hit the ground at the same time.

Explanation:

If we ignore air resistance or friction, the balls would hit the ground at the same time. The question does not state whether or not there is air resistance.

If there was air resistance, ball A would hit the ground first.

Again, there is no information provided on whether is is air resistance or not, so there is not enough information.

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.
