Two uniformly charged, infinite, nonconducting planes are parallel to a yz plane and positioned at x = -50 cm and x = +50 cm. The charge densities on the planes are -50 nC/m² and +25 nC/m², respectively. What is the magnitude of the potential difference between the origin and the point on the x axis at x = +80 cm? (Hint:Use Gauss’ law.)
Answer:
ΔV = 2520 V
Step-by-step explanation:
We are given;
Charge density 1; σ1 = -50 nC/m² = -50 × 10^(-9) nC/m²
Charge density 2; σ2 = +25 nC/m² = +25 × 10^(-9) nC/m²
Now, formula for electric field strength is;
E = -(½ε)(|σ1| ± |σ2|)
ε is vacuum permittivity with a constant value as 8.85 × 10^(−12) C²/N.m²
|σ1| and |σ2| means we are taking the absolute values and would therefore not use the negative sign attached to them.
Now, in between x = 0 cm(0 m) and 50 cm (0.5 m), electric field generated by both charge densities would be in the same direction and thus;
E_in = -(½ε)(|σ1| + |σ2|)
E_in = -(½ × 8.85 × 10^(−12)) × [(50 × 10^(-9)) + (25 × 10^(-9))]
E_in = -4200 V/m
In contrast, when x ≥ 50 cm (0.5 m), electric field generated by both charge densities would be in opposite directions and thus;
E_out = -(½ε)(|σ1| - |σ2|)
E_out = -(½ × 8.85 × 10^(−12)) × [(50 × 10^(-9)) - (25 × 10^(-9))]
E_out = 1400 V/m
The magnitude of the potential difference from the origin to x = 80 cm(0.8 m) is calculated as attached;
From the attachment, we see that;
ΔV = 2520 V

Answer:

Step-by-step explanation:
Jan and Julie went for a bike ride. They started their ride at 09:30 and finished at 15:15. • They stopped for a drink for 20 minutes • They took 45 minute for lunch • They rested for 10 minutes. How long were they riding on their bikes for? (excluding stops)
Given:
Jan and Julie started their ride at 09:30 and finished at 15:15.
Stopped for a drink = 20 minutes
Lunch = 45 minute
Rest = 10 minutes
To find:
Time they are riding on their bikes (excluding stops).
Solution:
Jan and Julie started their ride at 09:30 and finished at 15:15.
So, total time of ride including stops is 5 hours 45 minutes or we can say 345 minutes calculated as
[tex]30+60+60+60+60+60+15=345\text{ minutes}[/tex]
We need subtract Drink, lunch and rest time from the total time to get the Time they are riding on their bikes (excluding stops) is
[tex]345-20-45-10=270 \text{ minutes}[/tex]
Therefore, the total time they are riding on their bikes (excluding stops) is 270 minutes.

Meg is a veterinarian. I. Given week , 50% of the 16 dogs she saw were boxers . Steve is also a veterinarian. In the same week , 7 of the 35 dogs he saw this week were boxers. Each wants to know the record the part , the whole and the percent. Does meg need to find the part the whole or the percent
In this situation, Meg will need to find the whole because she already has the part and the percentage.
What is a whole?In mathematics, a whole represents the total number of items that are analyzed, in this case, the total number of dogs.
What is the part?The part refers to a number that is usually lower than the whole and describes specific characteristics. For example, in a classroom of 30 kids, 20 like to play basketball. Then 20 is the part.
What is the percentage?The percentage is the number followed by the symbol % and represents the relationship between the part and the whole. In this case, the percentage of boxers is related to the number of total dogs.
Based on this, Meg already has the percentage (50%), and the part (16), therefore, she needs to find the whole or the total number of dogs, in this case, 32.

which equation represents a line that is perpendicular to the line on the graph?
A) y=-4x+3
B) y= -1/4x+1
C) y=-1/x-2
D) y= 4x+4
===================================================
Explanation:
The given visual line has a slope of -1/4. We can see this by starting at (0,2) and we do two things
a) move down 1
b) move over to the right 4
This leads to slope = rise/run = -1/4
Once we find the slope of the original line, we take the opposite reciprocal. This is also called the negative reciprocal. So we'll take the reciprocal of -1/4 to get -4/1 or just -4. Then we flip from negative to positive.
In short we flip the fraction and the sign. That has us go from -1/4 to 4.
The original slope is -1/4. The perpendicular slope is 4.
Side note: multiplying any two perpendicular slopes leads to -1. Neither line can be vertical.
--------------------------
So we found the slope of the perpendicular line to be m = 4.
We don't know which point the perpendicular line goes through, so theoretically we have infinitely many equations to pick from. They are all in the form y = 4x+b. Note how I replaced m in y = mx+b with 4.
So our answer will be in the form y = 4x+b. Choices A through C don't fit the description. Only choice D does. So choice D is the answer.
With y = 4x+4, the slope is 4 and the y intercept is 4.

2/3y + x =4 Solve for y
Answer:
y = -3x + 12/2
Step-by-step explanation:
Step 1: Add -x to both sides
x + 2/3 + -x = 4 + -x
2/3y = -x + 4
Step 2: Divide both sides by 2/3
2/3y ÷ 2/3 = -x + 4 ÷ 2/3
y = -3x + 12/2

Answer:
x = 20
Step-by-step explanation:
Let's look at the first parallel lines (the ones with one arrow).
Because both these lines are parallel, we can say that (3x + 2) and (4x - 18) are equal due to the alternate interior angles theorem.
So we have to make both of these expression equal to each other, and then solve:
3x + 2 = 4x - 18
-x = - 20
x = 20 < --- this is your answer
Hope this helps!
