The net charge of 3 mol of protons isa) 4.81×10 4 C .
b) 3.00 C
c) 4.81×10 −19 C
d) 2.89×10 5 C

Answers

The charge of 1 mole of proton is equivalent to 1.60217656x10^-19 coulombs. This is also called an elementary charge. Multiply that by 3 to get the net charge of three moles of protons.

Charge of 3 mol protons = 3 x 1.60217656x10^-19 = 4.81x10^-19 coloumbs

So the answer is c) 4.81×10 −19 C

When is acceleration the greatest on a graph

Answers

Depends on the graph, but the answer is likely the slope. The greater the slope, the greater the change in whatever is being graphed. In this case velocity vs time.

Shear causes horizontal movement along a fault plane in a/n _______ fault. A. reverse B. strike-slip
C. normal
D. irregular

Answers

The answer is B. Strike slip fault. Shearing occurs when plates or blocks of rocks slide past each other in the opposite direction. This occurs at transform plate margins. An example is the San Andreas Fault running through California, USA. Compression occurs at reverse faults and tension at normal faults.
THE ANSWER IS B. STRIKE-SLIP

A gas is heated from 263 K to 298 K, and the volume is increased from 24 L to 35 L. If the original pressure is 1 atm, what would the final pressure be? *

Answers

Since for closed system moles of the gas is always conserved

so as per idea gas equation we can say

n = (PV)/(RT)

so here we can say

n_1 = n_2

so here we have

(P_1V_1)/(RT_1) = (P_2V_2)/(RT_2)

as we know that

T_1 = 263 K

T_2 = 298 K

V_1 = 24 L

V_2 = 35 L

P_1 = 1 atm

now from above equation

(1*24)/(263) = (P*35)/(298)

on solving above equation we have

P = 0.78 atm

so here pressure will be 0.78 atm

Final answer:

Based on the combined form of the ideal gas law, the final pressure of the gas, given the changes in volume and temperature, would be approximately 0.725 atm.

Explanation:

The question concerns the change in conditions of a gas and asks you to determine the final pressure. This deals with the combined form of the ideal gas law, which states that the product of the initial pressure and volume, divided by the initial temperature, equals the product of the final pressure and volume, divided by the final temperature (P₁V₁/T₁ = P₂V₂/T₂).

Given that the initial pressure P₁ is 1 atm, initial volume V₁ is 24 L, initial temperature T₁ is 263 K, final volume V₂ is 35 L, and final temperature T₂ is 298 K, we can substitute these values into the equation to solve for the final pressure P₂.

Therefore, P₂ = P₁V₁T₂ / V₂T₁ = (1 atm × 24 L × 298 K) / (35 L × 263 K) ≈ 0.725 atm. So, the final pressure of the gas would be approximately 0.725 atm.

A girl rides her moped 5.0 km east and then turns around and rides 2.0 km west. The entire trip takes 15 minutes. What are her average speed and velocity?

Answers

The girl's average speed is 28 km/h, and her average velocity is 8 km/h to the east.

Average speed and average velocity

To calculate the average speed and average velocity, we'll use the following formulas:

Average Speed = Total Distance / Total Time

Average Velocity = Total Displacement / Total Time

Given information:

  • Distance traveled east = 5.0 km
  • Distance traveled west = 2.0 km
  • Total time = 15 minutes = 15/60 hours = 0.25 hours

Total Distance = Distance east + Distance west = 5.0 km + 2.0 km = 7.0 km

Total Displacement = Final position - Initial position = 2.0 km east

Average Speed = 7.0 km / 0.25 hours = 28 km/h

Average Velocity = 2.0 km east / 0.25 hours = 8 km/h (east)

So, the girl's average speed is 28 km/h, and her average velocity is 8 km/h to the east.
