Answer & Explanation:
<u>use the principle of conservation of momentum</u>
<u>take right as positive and left as negative</u>
<em>momentum is the product of mass and velocity</em>
(4 x 8) + (6 x -2) = (4 x -4) + (6 x Y)
32 - 12 = -16 + 6Y
20 + 16 = 6Y
Y = 6m/s
Final answer the velocity of the 6 Kg ball is 6m/s
That distance is the definition of 1 AU.
The internal energy of an ideal gas is given by:
where
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
k=3 for monoatomic gases, k=5 for diatomic gases
In this problem, we have n=3.0 mol of a diatomic gas (k=5) at T=288 K. Substituting these numbers into the equation, we find the internal energy of the gas:
Electric current is the movement of the electrons caused by potential
difference. For example, in a circuit, the electrons in the bulb will not move
without the potential difference or voltage. When there is voltage, electric
current occurs because there is a driving force for the electrons in the wire
to move.
