Answer: The answer Is 9f
Step-by-step explanation:
The drawing shows three point charges fixed in place. The charge at the coordinate origin has a value of q1 = +8.00 µC; the other two have identical magnitudes, but opposite signs: q2 = -5.00 µC and q3 = +5.00 µC.
(a) Determine the net force (magnitude and direction(measured counter clockwise from the x-axis)) exerted on q1 by the other two charges
(b) If q1 had a mass of 1.50 g and it were free to move, what would be its acceleration?
(a) The net force equation on q1 is 10.6N towards q2. (b) The acceleration of q1 would be 6.8x10^7m/s^2.
a) The Coulomb's law equation for the force between two charges q1 and q2 is given by:
F = k(q1q2)/r2
Where k is the Coulomb's constant and r is the distance between the two charges.
Using this equation, the force on q1 due to q2 can be calculated as:
F12 = (8.99x109 N m2/C2)(8.00x10-6C)(-5.00x10-6C)/(1.00m)2
F12 = -44.8x10-6 N
Similarly, the force on q1 due to q3 can be calculated as:
F13 = (8.99x109 N m2/C2)(8.00x10-6C)(5.00x10-6C)/(2.00m)2
F13 = 55.2x10-6 N
The net force on q1 can be calculated as the vector sum of F12 and F13:
F1 = F12 + F13
F1 = 10.6N towards q2
b) The acceleration of q1 can be calculated using Newton's second law of motion:
F = ma
a = F/m
Where m is the mass of q1.
Therefore, the acceleration of q1 can be calculated as:
a = (10.6N)/(1.50g)
a = 6.8x107m/s2

O is the centre of the circle, work out the value of X.
Answer:
69
Step-by-step explanation:
The central angle is twice the inscribed angle. So the angle that is behind the one equal to 2x is equal to x. We know that the opposite angles in a circle add up to 180. Therefore, we can solve for x:
[tex]x + x + 42 = 180$^{\circ}$\\\\2x = 180$^{\circ}$ - 42$^{\circ}$\\\\2x = 138$^{\circ}$\\\\x = 69$^{\circ}$[/tex]
There i 64 inger in acquire the tenor and Soprano are in eparate row there are eight inger in each row there are four row of tenor how many row of Soprano are there
There are 4 rows of Soprano. The concept of algebraic manipulation is used to solve the problem.
Given the information that there are 64 fingers in total and 8 fingers in each row of the Tenor, I was able to determine that there are 32 fingers in the Tenor rows by multiplying 8 fingers/row x 4 rows.
Then, We subtracted the number of fingers in the Tenor rows (32 fingers) from the total number of fingers (64 fingers) to find the number of fingers in the Soprano rows, which is also 32 fingers.
Finally, We divided the number of fingers in the Soprano rows by the number of fingers per row (8 fingers/row) to find the number of rows of Soprano, which is 4 rows.
If there are 64 fingers in total and 8 fingers in each row of the Tenor, then there are 8 fingers / row x 4 rows = 32 fingers in the Tenor rows.
Since there are 64 fingers in total and 32 fingers in the Tenor rows, then there are 64 fingers - 32 fingers = 32 fingers in the Soprano rows.
Therefore, there are 32 fingers / 8 fingers/row = 4 rows of Soprano.

A sixth grade class is going on a field trip. The school is providing one sack lunch for each student. Each lunch has either a ham, turkey, or bologna sandwich along with either carrots or celery.
Identify which list below shows all the possible outcomes of sack lunches, and select the outcomes from that list that represent picking a ham or turkey sandwich with carrots if there are an equal number of each type of sack lunch and students are randomly selecting their lunch. Use this information to mark the probability on the number line.
Answer: List 2
Mark the midpoint between 1/6 and 1/2 (see diagram below)
======================================================
Explanation:
There are 3 meats (ham, turkey, bologna) and 2 vegetables (carrots, celery).
This gives 3*2 = 6 different combos of meat plus a vegetable. This is where we can only pick one of each type.
The 6 different combos are shown in list 2
List 1 is not correct because you can choose one vegetable only, and not have both.
----------
Look through list 2 and circle the options that say "ham, carrots" and "turkey, carrots". There are 2 items that are circled. This is out of 6 total.
We arrive at the probability 2/6 = 1/3
The fraction 2/6, aka 1/3, is located at the halfway point between 1/6 and 1/2. This is because 1/6+1/2 = 1/6+3/6 = 4/6, which divides in half to get 2/6.

What is a fraction?
If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.
Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.
Given that stamp of Height is 3in with 4 1/2 in width.
So 9/2 of width = 3 Height

(or ) = () + ().
According to the multiplication theorem of probability, the probability of both events and occurring is equal to the product of the probability of occurring and the conditional probability of event occurrence if event happens.
Let and are two events associated with the sample space . ∩ gives the simultaneous occurrence of two events and
We know that the conditional probability of the event given that has occurred is given by (∣) and is given by
(∣) = (∩)(), () ≠ 0
We can write the above equation as
(∩) = (∣)⋅()⋯()
Also, we can write
(∣) = (∩)(), () ≠ 0
(∩) = (∣)⋅()
Combining () and (), we can write
(∩) = (∣)⋅() = (∣)⋅(), where (),() ≠ 0
According to the addition theorem, if two events and , are mutually exclusive, the probability of either or occurring is the total of the individual probabilities of and .
Let event happen in ways, and event happen in ways. Then the total number of happening of events is , which is = +
Thus, the probability of events happening is given by (or ).
By the definition of probability,

Dee ued 2 1/3 cup of ugar for a cake recipe. If the amount of ugar the container hold i 3 time the amount he ued, doe the container hold more than, le than, or equal to 3 cup of ugar?
The container holds more than 3 cups of sugar, since it holds 3 times the amount used in the recipe.
To calculate the amount of sugar in the container, we need to first determine the amount used in the recipe. The recipe calls for 2 1/3 cups of sugar. This can be converted to a decimal by dividing by 3, resulting in 2.333 cups of sugar used in the recipe. Now that we know the amount used, we can calculate the amount the container holds.
1. 2 1/3 cups = 2.33 cups
2. 3 x 2.33 cups = 6.99 cups
The container holds 3 times the amount used, so we can multiply 2.333 cups by 3, resulting in 6.999 cups of sugar in the container. This is more than 3 cups of sugar, so the container holds more than 3 cups of sugar.

How can we find log 7?.
The logarithm of a number with respect to a base is the exponent to which the base must be raised to produce that number. In other words, log_b(x) = y means b^y = x.
To find log_7(x), we can use the change of base formula which is log_b(x) = log_c(x) / log_c(b).
So you can use the logarithm of base 10 (common logarithm) or base e (natural logarithm) and use the above formula to find log7
So for example, log7(49) = log10(49) / log10(7) or log7(49) = ln(49) / ln(7)

What are linear equations?When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."
There are both one-variable and two-variable linear equations.
Given the equations,
-2x + 4y = -10
2x + 2y = -8
adding both the equations so -2x and +2x will be eliminated
-2x + 4y + 2x + 2y = -10 - 8
6y = -18
y = -18/6
y = -3
substitute the value of y in equation 2x + 2y = -8
2x + 2(-3) = -8
2x = -8 + 6
x = -1
2: Given equations y = -x + 5 .........(1)
y + x = 5 .........(2)
equation 2 can be written as,
y = -x + 5
