Helium has an atomic mass of 4.00 atomic mass units.
The answer is vena cava
Hope this helps !!
•Independent: different color sand samples
•Dependent: temperature of the sand
•Control/constant (means the same thing) : Same containers, same time in sun, same thermometer
Explanation:
Q = CV
where C = capacitance
V = potential difference
Solving for C,
C = Q/V = (9.6×10^-9)(120 v)
= 1.15 microFarads
Answer:
(D) is correct option.
Explanation:
At a particular time, the potential energy of a rock is 500 J and its kinetic energy is 600 J.
It is required to find the mechanical energy of the rock. Mechanical or total energy is the sum of kinetic and potential energy. So,
TE = K+ P
TE = 500 J + 600 J
TE = 1100 J
So, the total mechanical energy of a rock is 1100 J. Hence, the correct option is (D).
