Answer: Option (c) is the correct answer.
Explanation:
An elastic object is defined as the object that is able to retain its shape when a force is applied on it.
For example, when we pull a rubber band then it stretches and when we withdraw the force applied on it then it retain its shape.
As we know that potential energy is the energy obtained by an object due to its position.
So, when we stretch a rubber band then it will have elastic potential energy as position of the rubber band is changing and since, it will retain it shape hence it has elastic potential energy.
Thus, we can conclude that a stretched rubber band has elastic potential energy.
A: w=mg w=13(9.8) w= 127.4
B: 13kg
C: w=mg w=13(1.6) w= 20.8
D: The force of gravity is less on the moon than on earth therefore making the dog weigh less.
Answer:
number of moles = 27.34 moles
the temperature of gas after it undergoes the isobaric expansion = 605 K
Explanation:
Given that:
V = 0.25 m³
P = 250 kPa
T = 275 K
V₂ = 0.55 m³
P₂ = 760 kPa
a)
Using ideal gas equation ; PV = nRT
b) To calculate the temperature of gas after it undergoes the isobaric expansion; we have:
Answer:
B i think is the answer
Explanation:
i feel like it is B because if you put them together and the answer is 1.5 so it is B
