The two bodies are being drawn together by a force of 10812 N, according to Newton's Law of Gravitation.
Every particle in the universe is drawn to every other particle with a force that is directly proportional to the product of their masses and inversely proportional to their separation from one another, according to Newton's Law of Universal Gravitation.
Symbolically, Newton came to the following conclusion on the strength of the gravitational force:
F = G(m₁ × m₂) / r²
F is the gravitational force between two bodies, m1 and m2 are the bodies' masses, r is the distance between their centres, and G is the gravitational constant of the universe.
According to the query,
satellite's mass is m1 = 1100 kg.
mass of earth = 5.98 ×10²⁴ kg
Radius of the earth = 6.37 × 10⁶ m
G = 6.67 × 10⁻¹¹ Nm² / kg²
Force = G(m₁ × m₂) / r²
Substituting the values,
F = 6.67 × 10⁻¹¹( 1100 × 5.98 ×10²⁴) /( 6.37 × 10⁶)²
=> F = 6.67 × 1100 × 5.98 × 10¹³ / 40.58 × 10¹²
=> F = 43,875.26 × 10 / 40.58
=> F = 10812 N

of her project done. If she can finish \frac{7}{45}
45
7
of her project each day, how many more days will it take her to complete it?
Answer:
4 days
Step-by-step explanation:
If Rachel has 7/15 of her project done, then she has 8/15 of her project left to complete.
Convert 8/15 and let it have a denominator of 45, and you get 24/45. If she can finish the rest of her project 7/45 each day, and she has 24/45 left to go, then divide 24 by 7, and you get 3 R3.
Afterwards round that to 4, because Rachel can't leave 3/45 of her project unfinished, she just doesn't have as much work the last day.
So then Rachel can finish her project in 4 days.
Hope this helps!
Answer:
4 days
Step-by-step explanation:
7/15 done ...then 8/15 to go
8/15 = 24 / 45 if she can do 7/45 per day, she will need 4 more days

34 In the appeal of the People v. Collins case (see Exercise 4.1.28), the counsel for the defense argued as follows: Suppose, for example, there are 5,000,000 couples in the Los Angeles area and the probability that a randomly chosen couple fits the witnesses’ description is 1/12,000,000. Then the probability that there are two such couples given that there is at least one is not at all small. Find this probability. (The California Supreme Court overturned the initial guilty verdict.)
The probability that there are two such couples given that there is at least one is 1 - (4999999/12000000) = 4/12 = 1/3.
What is probability?Probability is the measure of the likelihood that a given event will occur. It is expressed as a number between 0 and 1 (or 0% to 100%). A probability of 1 indicates that the event is certain to occur, while a probability of 0 indicates that it is impossible for the event to occur. Probability is used in a wide range of disciplines including mathematics, science, engineering, finance, and philosophy. Probability can be used to make predictions and help inform decision-making. By understanding probability, we can better understand the chances of certain outcomes and make more informed decisions.
This is because the probability that the first couple matches the description is 1/12000000, and the probability that the second couple matches the description, given that the first couple does, is 1/(12000000-1). Since there are 4999999 other couples, the probability that the second couple matches the description is (4999999/12000000). Thus, the probability that there are two such couples is 1 minus the probability that the second couple does not match the description, which is 1 - (4999999/12000000) = 4/12 = 1/3.

Write an equation for a parabola with x-intercepts (-1,0) and (3,0) ehich pass the point (1,-16)
The equation for a parabola with x-intercept is y = 4/3x² + 8/3x - 20.
What is equation?
In arithmetic, an equation could be a formula that expresses the equality of 2 expressions, by connecting them with the sign =.
Main body:
The equation has the form y = Ax² + Bx + C
Since (3,0), (-1,0), (1,-16) are points on the graph, we get the following system of equations:
9A + 3B + C = 0
A - B + C = 0
A + B + C = -16
Subtracting the first 2 equations and subtracting the 3rd equation from the first, we obtain:
8A - 4B = 0
8A + 2B = 16
Since 8A - 4B = 0, 8A = 4B. So, A = 1/2B.
Therefore, 8A + 2B = 16
6B = 16 So , B = 8/3 and A = 8/6
Since A + B + C = -16 and A = 8/6 , B = 8/3, we have 4 + C = -16. So, C = -20.
An equation of the parabola is y = 4/3x² + 8/3x - 20

slope-intercept form: [tex]y = -\frac{1}{10}x - \frac{9}{2}[/tex]
Step-by-step explanation:
Point-Slope Form:We can express any one-variable linear equation as: [tex]y-y_1=m(x-x_1)[/tex], where "m" is the slope, and [tex](x_1, y_1)[/tex] is some point on the graph.
We're given the equation in point-slope form: [tex]y-1=-\frac{1}{10}(x+8)[/tex], and if we want to make a line parallel to this line, we just need the slopes to be the same. So let's just look at the value in front of the parenthesis. This is given to be: [tex]-\frac{1}{10}[/tex]
We can use this same form, to develop an equation parallel to the given line, and passing through: [tex](-5, 5)[/tex]
Plugging the values into the point-slope formula, we get:
[tex]y-(-5)=-\frac{1}{10}(x-5)\\\\y+5=-\frac{1}{10}(x-5)[/tex]
From here we can also convert this into slope-intercept form, where "y" is isolated.
[tex]\\y+5=-\frac{1}{10}(x-5)\\\\y+5=-\frac{1}{10}x + \frac{5}{10}\\\\y + \frac{10}{2} = -\frac{1}{10}x + \frac{1}{2}\\\\y + \frac{10}{2} - \frac{10}{2} = -\frac{1}{10}x + \frac{1}{2} - \frac{10}{2}\\\\y = -\frac{1}{10}x - \frac{9}{2}[/tex]

a sequential circuit has two jk flip-flop a and b and one input x. the circuit is described by the following flip-flop input equations:
D flip flop stands for a delay flip flop that produces output that is identical to input after a brief delay. The flip flop's input and next state are equal.
Z is an output, and x and x inputs.
x'y + xA = DA= A*
B* = x'B + xA
z=A (output is independent of input) (output is independent of input)
The next states are A(t+1) and B(t+1). We must provide the next state value to D of the D flip flop in order to obtain the next states A(t+1), and B(t+1) for A, B(present state). So the sequential circuit will be:
To get the next state as A(t+1)= x’A + xA, B(t+1)= x’B + xA, we have to give them to DA, DB of D flip flop because for D flip flop whatever is given to DA, DB will appear at output A, B.

How many people would have to be at the party to guarantee that at least three people share the same birth date, birth month, and birth year? Note: assume the range of birth years include 2 leap years. (10 points)
at least 24 people must be in the party to guarantee that at least 3 people have the same date of birth, date of birth, date of birth.
To warrant that at least three people have the same date, month, and year of birth, we need to find the minimum number of people such that there is a probability that at least three people have the same date, month, and year. there is. Birth year she is 1 or more. Non-leap years have 365 days, and leap years have her 366 days. The birth year range includes two leap years, so there are 3652 + 3662 = 2,922 possible births. This means that the probability that a particular person's birthday is unique is (2922-1)÷2922 = 1÷2922.
Now we can use the birthday puzzle to calculate the probability that at least three people have the same birthday. The probability that no one has the same birthday is (1 - 1÷2922)^n, where n is the number of people in your party. At least he has 1-(1-1÷2922)^n probability that 3 of them have the same birthday. You can set this probability to 1 or more and solve for n.
1 - (1 - 1÷2922)^n >= 1
(1 - 1÷2922)^n <= 0
n >= log(0) ÷ log(1 - 1÷2922)
The logarithm of 0 is not defined, so you can use a small value on the right hand side instead. B. 10^-6. This will tell you:
n >= log(10^-6) ÷ log(1 - 1/2922)
n >= log(10^-6) ÷ log(2921/2922)
n >= log(10^-6) ÷ log(2921) - log(10^-6) / log(2922)
n >= log(10^-6) × log(2922) ÷ log(2921) - log(10^-6)
n >= log(10^-6) × log(2922) ÷ log(2921) - log(10^-6)
n >= 23.
Hence, at least 24 people must be in the party to guarantee that at least 3 people have the same date of birth, date of birth, date of birth.

the tension in each wire will be equal. The tension in each wire, T ,the tension in each wire is 85.36 N with its weight.
Assuming that the tool has negligible mass so that its weight does not contribute to the tension in the wires, the tension in each wire will be equal. The tension in each wire, T, can be calculated using the equation:
T = (W/2) + (L/2)*sin(θ),
where W is the weight of the shelf and L is the length of the shelf. The angle θ is the angle between the ceiling and the shelf.
In this case, W = 50 N, L = 50 cm and θ = 45°. Therefore, T = (50/2) + (50/2)*sin(45) = 50 + 35.36 = 85.36 N.
