A 2.0kg object is raised by a height of 0.5m.Calculate the energy raised in its gravitational potential energy store? G=9.8N/KG
1 answer:
Answer:
Gravitational potential energy stored is 9.8 J.
Given:
G = 9.8
height = 0.5 m
mass = 2 kg
To find:
Gravitation Potential energy stored = ?
Formula used:
Potential energy = mGh
m = mass
G = acceleration due to gravity
h = height
Solution:
Potential energy of the object is given by,
Potential energy = mGh
m = mass
G = acceleration due to gravity
h = height
Potential energy = 2 × 9.8 × 0.5
Potential energy = 9.8 Joule
Gravitational potential energy stored is 9.8 J.

Answer:
Explanation:
First of all let's define the specific molar heat capacity.
(1)
Where:
Q is the released heat by the system
n is the number of moles
ΔT is the difference of temperature of the system
Now, we can find n with the molar mass (M) the mass of the compound (m).
Using (1) we have:
