All we can say is that the object's volume is about 41 liters. That's the same as the volume of water displaced.
We can't say anything about the object's weight. There is no direct connection between the weight of the object and the weight of the water it displaces.
Answer:
17 kJ
Explanation:
q = mCΔT
q = (55 kg) (4.184 kJ/kg/K) (360 K − 285 K)
q = 17,000 J
Answer:
A. 98,000 J
Explanation:
The gravitational potential energy of an object is given by
U = mgh
where
m is the mass of the object
g is the gravitational acceleration
h is the heigth above the ground
In this problem,
m = 2000 kg
g = 9.8 m/s^2
h = 5.0 m
Substituting into the equation, we find
Answer:
zero
Explanation:
There are three forces acting on the piston
1. force due to atmospheric pressure = F1 downward
2. force due to gaseous pressure = F2 upward
3. force due to the weight placed on the piston = F3 = mg downward
As the piston is in equilibrium condition, so the net force on the piston is zero.
