Answer:
0.25 cm³.
Explanation:
We shall apply Boyle's law to find the solution . According to it
PV = constant where P is pressure and V is volume of the gas.
P₁ V₁ = P₂V₂
1 x .5 = 2 x V₂
V₂ = 0.25 cm³.

Explanation:
Answer:
Higher current is normally achieved by faster moving electrons.
Explanation:
- Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.
- Current is the net charge flowing per unit time.
- Current can be represented by:
I=v×e×N×A
where,
I= current
e= electric charge
v= speed of electrons
N=no. of free electric charges per volume
- The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.
Answer:
144 watt
Explanation:
resistance, R = 100 ohm
L = 4 mH
C = 100 micro farad
At resonance, the impedance is equal to R
Z = R
Vrms = 120 V
Irms = Vrms / R = 120 / 100 = 1.2 A
Power is given by
P = Vrms x Irms x CosФ
Where, CosФ is called power factor
At resonance, CosФ = 1
Power, P = Irms x Vrms
P = 1.2 x 120 x 1
P = 144 Watt.
Thus, the power is 144 watt.
