Thank you, thank you!
So the equation becomes
Pa - 1/2 *pair * vair^2 + pwater * gL = Pa + poil *gL
- 1/2 *pair * vair^2 + pwater * gL = poil *gL
1/2 * pair * vair^2 = (pwater - poil)gL
Now vair...

One more thing. Is it correct to say that in figure (c), P1 will be equal to Pa? When the air is blown, then will the air pressure in left tube not be reduced?

If I do like that for figure (c), then
Pa + 1/2 *pa *v^2 + pwater *gL
= Pa + poil *gL
Subtracting Pa from both sides,
1/2 *pa *v^2 + pwater *gL = poil *gL
1/2 *pa *v^2 = (poil - pwater)gL
But...

When the satellite is closer to the Earth, then it has smaller gravitational potential energy. Hence, larger kinetic energy and thereby larger speed.

Let theta = angle of inclination
What are the forces on the car? There are three forces
1. Force of gravity vertically downward
2. Normal force perpendicular to the incline
3. Friction force up...

Sorry for causing the confusion. But Capuchin has explained. Yes the suffix I means "incident" and r means "refracted".

XM8,
I cannot see the diagram. Please check the link. But, from your explanation, I can say that your understanding is correct.

You asked for an example. Consider the following:-
A light ray...

The speed of light is maximum in vacuum. In vacuum, the speed is 3 * 10^8 m/s. To be accurate, it is 299,792,458 m/s, which is very close to 3 * 10^8 m/s. In other media (e.g. glass, water etc.), the...

Are all four on the same side of the desk?
Net force is non-zero. So what do you think will happen according to Newton's 2nd law? Will the velocity remain constant? Or will it change?

Odds are 5 to 8
P(A) = 5/13
P(not A) = 1 - 5/13 = 8/13
Odds of A occurring = P(A)/P(not A) = 5/8 i.e. 5 to 8

Hi Cough,
By PM I do not mean sending me request through PM. What I mean is that the asker should post question in this site and if I am not replying, then he should send me a PM saying that he has...

I saw this thread just now. Do not know if you still need help. In future, if you need help urgently, then do send me email. My contact info are there in my profile.

I do not know why I did not receive mail stating that somebody sent me PM. Just now I saw the PM.
The word is pronounced as nirvaana. Roughly it means "becoming spiritually liberated".

As the spring is released, the mass moves up. So its gravitational potential energy increases. You need to consider that too. That is what I did in my previous post.

You have ignored the change in gravitational potential energy.
Change in K.E. = 0.5 * m * v^2 = 0.5 * 0.03 * v^2 = 0.015 v^2
Change in spring P.E. = 0 - 0.5*24*0.1^2 = - 0.12 J
Change in...

1) M = 1000 kg
g = 17.5 m/s^2
Gravitational attraction = Mg
So just multiply M and g and you will get the answer. The result will be in N.

v = 15 m/s
t = 5.6 s

Multiply power and delta time. You will get the answer in J (i.e. Joule).
This is because Watt * second means Joule.

This is not a homework question because I have completed my school/college. I am posting this question here because somebody asked me and it confuses me. So I want to know (as soon as I can) how to...

2)Initial speed vo = 0

Yes, I assumed that the question is to find torque to spin the wheel. That is what the question appeared to me.

I will post the answer sometime tomorrow. Meanwhile you may look into the following software. You may find it useful: -

For writing in Sanskrit

It means "Om". It is sacred symbol in Hinduism.
But note that in the image attached by you, Om is written reversed - like how mirror reverses.

Good drkpp. But don't you think that moolbhoot is even better?

Another Sanskrit word for "enemy" is "shatru". It is written as

How do you pronounce these names?

Isn't fortitude same as patience?

Patience is

Shiama in Sanskrit:-

I am assuming that this is pronounced like
Shi-yaa-maa
(Note: I of shi is a short I)

If this is how you pronounce, then Shiama is written like...

How you write your name in Sanskrit depends on how you pronounce your name.
I am assuming that "D" in "DEREK" is pronounced like "De" of "Dentist".
"Re" is pronounced like "Re" of "Red".
If so,...

Hi Capuchin,
You are right. I did not realise that it was homework question. I thought the questioner was asking out of interest.
Anyway, I will take care in future.

Remember the formula:
Area = 1/2 * base * altitude

Area A = 30 sq. units
Base b = 6 units
Let altitude = a

A = 1/2 * b * a
A and b are known. From above formula, you can calculate a.
