Answer:
The correct option is;
The graduate cylinder with more water has more thermal energy because it is holding more water molecules
Explanation:
Given that the thermal energy of the system is the energy possessed by the system by virtue of the increased motion of the particles by virtue of a transfer of heat, when the content of the system is heated
The thermal energy, Q is given by the following equation;
Q = Mass, m × The specific heat capacity, C × The change in temperature, ΔT
Given that the graduated cylinder with more water has more mass and therefore, more water molecules, than the cylinder with less water, the cylinder with more water has more thermal energy.
Answer:
126.99115 g
Explanation:
50 g at 90 cm
Stick balances at 61.3 cm
x = Distance of the third 0.6 kg mass
Meter stick hanging at 50 cm
Torque about the support point is given by (torque is conserved)

The mass of the meter stick is 126.99115 g
Answer:
, downward
Explanation:
There is only one force acting on the ball during its motion: the force of gravity, which is given by

where
m is the mass of the ball
is the acceleration of gravity (downward)
According to Newton's second law,

where F is the net force on the object and a is its acceleration. Rearranging for a,

As we said, the only force acting on the ball is gravity, so F = mg and the acceleration of the ball is:

Therefore, the ball has a constant acceleration of
downward for the entire motion.
