An element is a substance made of many atoms of the same kind. Silver and gold are different elements, for the following reason:
- silver is an element whose atoms have atomic number 47 (i.e., an atom of silver contains 47 protons and 47 electrons)
<span>- gold is an element whose aroms have atomic number 79 (i.e., an atom of gold contains 79 protons and 79 electrons)</span>

The electric potential inside a parallel-plate capacitor __________.
tresset_1 [31]

Answer:

\Delta V=\frac{Q d}{A \epsilon_0}

Explanation:

for the calculation of the electric potential inside a parallel plate capacitor you can use the formula for the electric field inside the capacitor.

\Delta V=V(d)-V(0)=\int_0^dEdx

where d is the distance between plates and E is the electric field, which is given by:

E=\frac{\sigma}{\epsilon_0}

By replacing you obtain:

\Delta V=E\int_0^ddx=Ed=\frac{\sigma d}{\epsilon_0}=\frac{Qd}{A\epsilon_0}

where Q is the charge stored by the capacitor and A is the area of the plates.

hence, the answer is Qd/Ae0

A student pushes a laptop cart down the hallway by applying 20 Newtons force. The student pushes it 10 meters and
noname [10]

Answer:

None.

Explanation:

  • By definition, work is a process that it happens when an applied force

        causes an object to change its position, i.e. to have a displacement.

        Since the laptop cart is at rest while he stops at the water fountain, no  

       net work done is on the laptop cart.

what is the vapor pressure of water if the total vapor pressure is 1.5 atm and the pressure of oxygen is 0.2 atm?
andreyandreev [35.5K]

Since the total pressure of each gas is the sum of the partial pressures of all the individual gases, the vapor pressure of oxygen is  1.3 atm.

From Dalton's law of partial pressure, the total pressure is the sum of the individual partial pressures of the gases;

PT = PA + PB + PC + --------

Given that;

Vapor pressure of oxygen = 0.2 atm

Total pressure = 1.5 atm

Vapor pressure of oxygen = ?

Partial pressure of oxygen =  1.5 atm - 0.2 atm = 1.3 atm

The vapor pressure of oxygen is  1.3 atm.
