Answer:
force of gravity; weight
Explanation:
Weight is the force of gravity on an object and it is measured in Newtons. On this spring scale, each line equals one Newton.
Answer:
B. A large number of atoms move from one place to another
Explanation:
Convection is heat transfer by the movement of atoms of a substance from one region to another across a temperature gradient. Since atoms of solids are rigidly held in place, convection only occurs in liquids and gases since they flow.
Convection occurs when the temperature of one region of a fluid (liquid or gas) is higher than its other region. There is thus a mass movement of atoms from one region to the other due to a temperature difference. The atoms will continue to move to the region of lower temperature until the temperature of both regions are the same at an equilibrium temperature.
Answer:
False
Explanation:
Something with high specific heat cooling down would take longer to heat up.
The increase in potential energy is
Explanation:
The gravitational potential energy gained by an object lifted above the ground is given by:
where
m is the mass of the object
g is the acceleration of gravity
is the change in height of the object
For the beam in this problem, we have
m = 330 kg
Substituting, we find its gain in potential energy:
