Answer:
23895.05 Pa
Explanation:
V = 0.03 m³
mass, m = 4 g
Temperature, T = 388 K
Let P be the pressure.
number of moles, n = 4 / 18 = 0.22
Use ideal gas equation
PV = n RT
P x 0.03 = 0.22 x 8.314 x 388
P = 23895.05 Pa
Thus, the pressure is 23895.05 Pa.
Answer: The energy required to change water from a liquid to a solid is 333.7 kJ/kg while the energy required to boil water is 2257 kJ/kg. The amount of energy needed to change the phase of water to a gas from a liquid is 540 times the amount of energy needed to raise the same amount of water 1° C
Explanation:
Iron and nickel are the elements most similar to cobalt
Answer: The correct answer is "the same magnitude of force, 60 N should be applied".
Explanation:
Balanced forces: These forces are balanced when the forces are acting equal in magnitude but opposite in direction. The balanced forces will not cause any change in the speed of the object.
Unbalanced forces: These forces are unbalanced when the forces acting on the object are not equal in magnitude. It will cause the change in the speed of the body.
In the given problem, Jennifer stands on one side of a filing cabinet and pushes with a force of 60 N. If Nathan wants to help Jennifer demonstrate balanced forces, then he should apply the same magnitude of force of 60 N.
