How to calculate specific enthalpy of water if pressure and temperature are given.(by using steam table)?

No we cant. Gotta choose one of the two cords because one of the two cords should reach the maximum force 1st.

Hie guys, Two cords can each support a maximum load of 100 N,we need to find the maximum weight of crate that can be hoisted at contant velocity. My question is which cord am i suppose to consider as 100N?

That was helpful.thanks a lot!

Thanks a lot:biggrin:

Its a = \left( 2 \pi f\right)^{2} x. I dint knew the 2nd equation but i get it now. stiffness is proportional to frequency according to that.but does the natural frequency of spring increases as well?

a=[2pie f]^2x. So if k increases f increases which increases a(acceleration) and according to the formula given at the start frequency increases. If that make sense:blushing:

Thanks a lot bro:wink:

Its P/3m so force is P/3.ohh ya! But is always the force distributed equal in frictionless surface?

Homework Statement three numbered cubes each of mass m placed in contact on a frictionless horizontal surface. A steady horizontal force P is applied to the end surface of 1st cube. question:will the force on each cube be P/3?

So is that the only use for less heat capacity?

Metals have the low specific heat capacity.why is the low specific heat capacity useful?
