PV = nRT ....... ideal gas law
divide state 1 by state 2
WARNING: CONVERT ATM TO KPA
(0.923atm)(150ml) / (0.987atm)(V2) = 1
1 because constant temperature
solve for V2. all the best
Answer:22.4 Magnetic Field Strength: Force on a Moving Charge in a Magnetic Field . ... Solution (a) To calculate the number of beats she has in 2.0 years, we need to ... (b) The distance from start to finish is the magnitude of the difference between the ... How much greater is the internal energy of the helium in the balloon than it ...
Explanation:
First of all,
The electric field at the surface of the sphere is given by
E = kQ/r²
The field strength at which breakdown occurs in the air is <span>3.0 MV/m
</span>
So, E = 3.0 MV/m
<span>The sphere potential is defined as
V = kQ/r</span>
<span>If we divide E/V we get
E = V/r </span>
<span>r = V/E = 20000V / 3.10^6 V/m = 6.66 </span>10^-3 m = 6.66 mm
2. Charge
<span>V = kQ/r .............>>
</span>
Q = Vr/k = 20000V *( 6.66 10^-3 m)/ (9.10^9 N m2/C2) = 1.481 10^-8 C
Answer: 20 minutes
Explanation: omm its 20 minutes
Answer:
B
Explanation:
Because according to the bolye law . Pressure is inversely propotional to volume . So higher the pressure lower the volume. P1×V1=P2×V2
