Wavelength = velocity/frequency of time .....(1)

Here we know that

frequency =1/T

By putting value in equation (1) or formula

340×0.01=3.4 ans

I am sorry but am not able to explain derivation  because it needs diagram and without you can't understand it but if you wanted tell me i will try

By the way you can use career 360 sites question papers

I hope it will help you

Thank you

I remember Omega(w)Angular Frequency for this single block system is (k/m)^0.5. Hence you get the Solution as 2(Angular Frequency).

As far as the Second part of your Question is concerned, please refer any Standard Physics Textbook, you will get the details. Its is one of the most fundamental aspects of Physics.

Hello candidate,

The equation of continuity suggests that any liquid flowing in a medium if it is incompressible and has a continuous inform velocity while flowing, then the volumetric flow rate at two points in the motion is constant.

The Mass is of 3000 kg, and the force needed to lift it is equal to 3000*9.8= 29400 Newton.

Hope this information was helpful for you!!

Good luck.

Dear Aspirant

Kepler's three laws of planetary motion can be stated as follows:

1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci.

2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.

3)the square of a planet’s orbital period is proportional to the cube of the semi-major axis of its orbit.

And

girder shape is done when a beams have very high moment of inertia for the same volume of the given material. ... The two horizontal parts (called flanges) of the I beam can bear high bending and shearing stress. That means they do not get twisted and tilted easily. That is why they are used in girders

i hope it will help you

Thank you

Dear aspirant,

Work is the energy transferred from the object via the application of force along the displacement.

Power is basically the amount of energy transferred per unit time.

Work done by a variable force is the integral of F.dx where F is the force and dx is the displacement.

Newtons second law is said to be the real law of motion since its generates the Equation of Motion of any particle and is quite appreciably the only law which can govern all the physics. From the first and second law we get the 3rd Law.

So the reason can be correct as we get from 1st and 2nd law but the assertion is wrong.

I hope this answer helps. All the very best for your future endeavors!

Dear Student,

This is just simple theoretical concept based question that you are asking here.You have to find a solution in book and have to prove this assertion as true or false.You will be able to find the solution in your book.Please do your assignment by yourself.

Thanks

Dear Student,

This type of question is just simple theoretical concept based you should study from books and read them because you will be here find the solution but you will not able to  remember it.This assertion is true and you need to prove it.

Thanks

Dear Student,

First Part:

• The air at the closed end is not free to vibrate so a node is fromed at the closed end.
• While the air at the open end is free to vibrate with maximum amplitude so an antinodes is formed at this end.
• This is the simplest mode of vibration and it is called fundamental mode.

Second Part:

This frequency is called the fifth harmonic or second overtone. Thus we see that frequencies of the modes of vibrations are in the ratio n:n1:n2: = 1:3:5 This shows that only odd harmonics are present in the modes of vibrations of the air column closed at one end.

Thank You.

Hello Dear,

The change in the pitch when there is a relative motion between source and observer is called Doppler's effect. Let a source at rest be emitting the waves of frequency f and wavelength λ. Let V be the velocity of wave emitted by source V=fλ. Let the distance between source and observer be V. Please elaborate your question and feel free to ask your doubts here for quick resolution of your query.

good Luck
