A gas occupies 11.2 liters at 0.860 atm. What is the pressure if the volume becomes is doubled? * 3 points Doubled Quadrupled Decreased by a factor of 4 Half as much as it was

Half as much as it was

Explanation:

According to Charles law

PV = k

P is the pressure

V is the volume

If PV= k, then P1V1= P2V2

P1 and P2 are the initial and final pressure respectively

V1 and V2 are the initial and final volume respectively

Given

V1 =11.2litres

P1 = 0.860atm

If the volume is doubled, V2 = 2(11.2) = 22.4litres

Get P2

P2 = P1V1/V2

P2 = 0.860×11.2/22.4

P2 = 0.860/2

P2 = P1/2 (since P1 =0.860)

P2 = 1/2 P1

Hence the pressure becomes halved if the volume is doubled

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
