Answer:
615 J
Explanation:
internal energy (U) = 504 J
heat lost (q) = 111 J = - 111 J (negative sign is because heat is lost)
work done = 222 J
what is the final energy in the system
total energy = final energy - initial energy
final energy = total energy + initial energy
where
initial energy = 504 J
total energy = 222 - 111 = 111 J
final energy = 504 + 111 = 615 J
It is commonly perceived as "thickness", or resistance to pouring. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is "thin", having a low viscosity, while vegetable oil is "thick" having a high viscosity.
Answer:
potential energy
Explanation:
this is because potential energy= mgh
so when m= 2m
p.e. = 2 times the previous value
Therefore , When mass is doubled , Potential energy gets doubled. When mass is halved , Potential energy decreases by half.
Answer:
g ≈ 2.82 m/s^2
Explanation:
By W = mg,
W = weight (in newtons)
m = mass (in kg)
g = gravitational acceleration (in m/s^2)
g ≈ 2.82 m/s^2
