A parallel-plate capacitor is created of 2 square plates, dimension L×L, be separated by street d. The plates are given charge ±

jajalger2018.org: A) 2 B) 4 C) 1

Explanation:

The electric field from a parallel-plate capacitor is provided by:

A) E=Q/(L^2 * ε0) therefore if we placed a charge dual the final electric field is twin that the original.

You are watching: No work is done by gravity on a bowling ball that rolls along a bowling alley because

B) from the over expression for the electric field, If the dimension of the bowl is double, climate the E final is 4 times weaker the the original.

C) If the distante in between plates is double the final electric field is the very same that initial.

A 0.275 m^3 tank consists of hydrogen (H2) at a temperature the 10° C and also a gauge press of 3.55 x 10^4 Pa. (a) What is the absolu

jajalger2018.org:

a) 283 K

b) 136825 Pa

c) 15.992

d) 1878.6 m/s

Explanation:

a)

T = pure temperature = 10 °C = 10 + 273 = 283 K

b)

*
= Atmospheric press = 101325 Pa

*
= gauge push = 35500 Pa

Absolute pressure is given as

*

*

*
Pa

c)

*
= variety of moles of Hydrogen

*
= Volume the hydrogen = 0.275 m³

Using the equation

*

*

*
= 15.992

d)

*
= Molar massive of hydrogen = 2 g mol⁻¹ = 0.002 kg mol⁻¹

*
= root average square speed

Root average square rate is provided as

*
