Must two quantities have the same dimensions if you are using one quantity as an exponent in raising other to a power? What is the dimension ( or dimensionless) of '2' in mv2/r ?( v is raised to the second power)

Thanks

Are exothermic reactions violation of law of conservation of mass , because energy and mass are equivalent? Please clarify!

I am confused! . In some books it is written that if the multiplier is less than 3.162 , the order of the magnitude of the number is the power of the ten in scientific notation , while in some books it is written less than 5 . What is right? Help!

Homework Statement Acceleration 'a' of a particle moving in a straight line as a function of velocity 'v' is given as a = g-Kv where 'g' and 'K' are constans . if the object starts from rest then velocity of the object after very long time is ?[/B] Homework Equations a= v dv/dx I don't know...

Thank you very much.wonderful answer

Is H2O a biomolecule?

Solomon's and fryl is best!

Finally got it☺☺! I was making the mistake in doing the integration. Nothing make you more happy than doing a good physics problem.

Thank you . I will try my best to solve it. Tomorrow , it's night here

Thank you all for all your help ! I don't think I am made for physics. I can't even solve problems like this. It is good that I am in my beginning of my course ,I can leave it it will be good for me.

Gneill ,the subscript on v is just 'x' indicating velocity in x direction.

This is the question! the answer is option III.

I'm still not getting it. I have done the integration but not sure what, how to take limits.

Homework Statement A particle is moving along the x-axis has acceleration 'f' at time ' t ' given by : f= f°(1- t /T) where f° and T are constants .The particle at t = 0 has zero velocity . In the time interval between t= 0 and the instant when f= 0 ,the particle's velocity is ? Homework...
