Answer:
This question is an example of Boyle's gas law which states that the pressure of a given mass of a gas is inversely proportional to its volume at a constant temperature. The formula for this gas law is:
P1·V1 = P2·V2
P1 = initial pressure = 1.7 atm
V1 = initial volume = 4.25 L
P2 = final pressure = 2.4 atm
V2 = final volume = ?
Rearrange the formula to isolate V2. Substitute the known data and solve.
V2 = P1·V1/P2
V2 = 1.7 atm·4.25 L/2.4 atm = 3.0 L to two significant figures
The new volume will be ~3.0 L.
Explanation:
The force between two parallel wires carrying currents in the same direction is attractive. It is repulsive if the currents are in opposite directions.
Answer:
A=0.80
Explanation:
a=2×100/time^2. a=2×100/15.86^2. = a=0.80
It is the very last answer
B is the only answer that makes sense.
A that would mean the car only moves 5 mi/hr
C just doesn't make sense
D the equation never mentions the velocity changing
