Answer:
10628.87 J
Explanation:
We are given that
Force applied =F=5592 N
Displacement=D=3.79 m
We have to find the work done in sliding the piano up the plank at a slow constant rate.
Work done=
The perpendicular component of force=
Work done =
Hence, the work done in sliding the piano up the plank at a slow constant rate=10628.87 J
Answer:
To Calculate Molecular Mass of O3
you should know Atomic mass of O
Atomic mass of oxygen(O) = 16
As O3 consist 3 atoms ,
So, Molecular mass of O3 =>3× 16
=> 48 g/mol
=> 0.048 kg/mol
Answer:
When a forming planet is big enough, it starts to clear its path around the star it orbits. ... A planet's gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle.
Answer:
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is ΔU = Q − W.
The internal energy of ideal gas is U = cV The change in internal energy for ideal gas is therefore ∆U = cV ∆T, where cV is specific heat (at constant volume), and ∆T is change in tem- perature.
