For this case, in the next item we have gravitational potential energy:
An apple in a tree.
Suppose we define our reference system at the floor level.
Suppose the apple is at a height h from the floor and has mass m.
The gravitational potential energy of the apple is given by:
U = mgh
Where,
m: apple mass
h: height of the apple with respect to the floor
g: acceleration due to gravity
Answer:
C) an apple on a tree
Answer:350.92 KJ/kg
Explanation:
Given the process is reversible adiabatic i.e it is isentropic
From steam table
For isentropic process 
at
Therefore Work output of the turbine per unit mass of steam is =
=3317.03-2966.11
=350.92 KJ/kg
Answer:
Light intensity refers to the strength or amount of light produced by a specific light source .
It is called a warm front when a warm air mass moves into an area where a cold air mass is located based on the blanked sentence above. A warm front is a condition where a warm air mass is replacing a cold air in a place. The character of a warm front condition is an increasing in temperature of a place which is caused by the moving warm air mass<span>.</span>
