A Van de Graaff generator is charged so that the electric field at its surface is 88000 N/C . What is the magnitude of the elect
dolphi86 [110]

Answer: 1.3617×10^-14 N

Explanation: The formulae that relates electric field intensity, magnitude of charge and force is given by the formulae below.

F = Eq

Where F = electric force =?

E = strength of electric field = 88000 N/c

q = magnitude of proton charge = 1.602×10^-19 c

By substituting the parameters, we have that

F = 88000 × 1.602×10^-19

F = 13.617×10^-15

F = 1.3617×10^-14 N

a balloon rubbed against denim gains a charge of -8.0 x 10^-6 c. What is the electric force between the balloon and the denim, w
DedPeter [7]

Answer:

230.4 N

Explanation:

Applying,

F = kqq'/r²..................... Equation 1

Where F = Electric force, k = Coulomb's constant, q = charge in the ballon, q' =  charge in the denium, r = distance between the charges.

From the question,

Given: q = -8.0×10⁻⁶ C, q' = +8.0×10⁻⁶ C, r = 0.05 m

Constant: k = 9×10⁹ Nm²/C²

Substitute these values into equation 1

F = (9×10⁹×8.0×10⁻⁶×8.0×10⁻⁶ )/0.05²

F = (576×10⁻³)/0.0025

F = 230.4 N.

Calculate the volume that 42g of nitrogen gas (N2)occupies at standard temperature and pressure.​
luda_lava [24]

Nitrogen gas has a molar mass of about 28.0134 g/mol. Then we have a starting amount of

(42 g) / (28.0134 g/mol) ≈ 1.4993 mol

of N₂.

At standard temperature and pressure, one mole of an ideal gas occupies a volume of about 22.4 L. Then 42 g, or 1.4993 mol, of N₂ takes up

(1.4993 mol) × (22.4 L/mol) ≈ 33.6 L
