Explanation:
The kinetic-molecular theory of gases can be stated as four postulates: A gas consists of molecules in constant random motion. Gas molecules influence each other only by collision; they exert no other forces on each other. All collisions between gas molecules are perfectly elastic; all kinetic energy is conserved.

Current flowing in a circuit depends on two variables. Identify these variables and their relationship to current.
A) Current is proportionate to the conductance of the circuit and precisely proportional to the voltage applied across the circuit.
B) Current is conversely proportional to the electrical tension of the circuit and corresponds to the resistance across the circuit.
C) Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.
D) Current is commensurate to the resistance of the circuit and directly proportional to the electric pressure applied across the circuit.
Answer:
C) Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.
Explanation:
Now Ohms Law states that, "So long as a physical state of a conductor remains the potential difference applied to the conductor is directly proportional to current flowing through it."
I ∝ V
V=IR also I=V/R
where R is the Resistance
Hence, From above equation we can say that Current increases when there is increase in Voltage but Current decreases as the resistance decreases.
Hence,Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.
K.E =1/2mv2
M=6kg
V=3m/s
K.E=1/2 X 6 X 3 X 3
=1/2 X 6 X 9
=27 J
In middle school, the formula you'll use most often when you're
working with acceleration is . . .
Acceleration = (change in speed during some time) / (time for the change)
