Answer:
The melting and boiling point of water in Fahrenheit scale is divided into 180 equal intervals, that means each division denoting 1°F.
division means their melting and boiling point is divided into 180 equal intervals that means each division indicates 1 degree F.
Answer:
W= 638.1 J
Explanation:
As we know that
Work done is the area of the force and displacement diagram.
W=∫F.dx
W=Work
F=force
dx=Elemental displacement
From the diagram ,area A
A= 60 x 7.09 + 1/2 x 60 x 7.09
A= 638.1 J
So the work W
W= 638.1 J
