So nice 👍
Q 5 correct answer is power
Rate of doing work is called power ....( Unit : P=Work/time = joule / sec ) 1:17
This product of moment of inertia and angular velocity yields kg⋅m2⋅s−1 or the joule-second.
Very important
Light is a form of energy that travel like a wave
Pinhole camera has *no lenz*
Very imp questions thanku sir please provide more questions. Physsics and chemistry
Light is the form of energy it can do various kinds of work

The answer of q no.5 is correct
A-0-A! Sir (in Qs:19) "Light" is the FORM of "Energy" but in video the selected Ans is "Waves".What is this?
Light contains characteristics of both waves and particles. Particles are described as packets of energy, which are called photons. When light rays travel from one medium to another, like air to water, these linear paths are altered. So in the continuity of its motion, light travel in waves.
Sir Q.19 ka answer energy not wave.
Yes
19 energy sir answer
Yes it's energy
Q 12 option A i think
Plz guide sir!
@@MAsif-el8ekCorrect answer is D.
Sir plz upload video on daily basis
yes, inshaAllah
Sir Q#23's answer is wrong 6:15
A pinhole camera does not have a lens. In fact, that's what makes it a pinhole camera!
A pinhole camera is a simple optical device that projects an inverted image of the outside world onto a surface inside the camera, without using a lens. Instead, it uses a small pinhole (a tiny aperture) to focus the light.
So, no lens is needed in a pinhole camera - just a tiny pinhole to focus the light!
Good❤
Light is form of energy not wave that's wrong answer sir

Yes
19 no wrong xa sir
Q no. 10 wrong ans
How?
plz tell that these mcqs are helpful for pu or not
These mcqs are for all kinds of exams
Q: 10 and 19 are wrong sir
both are correct
Dielectrics are non-conducting materials because they have no free charge carriers.
light is an electromagnetic waves
If you have an query, feel free to ask
Pinhole camera has zero lens
