How many different quantum states are possible if the principal quantum number is n = 4?
The possible quantum numbers for the value of n=4 will be i=0,1,2,3.
What is quantum number?
The number of elements in a quantum is the count of 0 to n - 1 where n is the principal quantum number. There are 4 different values of i in quantum number n =4.
Given that:
[tex]n=4[/tex] -- quantum number
To count the quantum numbers (i), we make use of the following set:
[tex]i=[0,1,2,3............n-1][/tex]
The value of n is: [tex]n=4[/tex]
So, the set will be populated as follows
[tex]i=(0,1,2,3)[/tex]
The number of elements in the set is 4.
This means that there are 4 different values of i

These proteins identify and lock on to an antigen (pathogen) and then tell other parts of the body to destroy the germ
A. T Cells
B. Phagocytes
C. Antibodies
D. Lymphocytes
Answer:
Answer is D.
Lymphocytes.
Explanation.
How Does the Immune System Work? When the body senses foreign substances (called antigens), the immune system works to recognize the antigens and get rid of them. B lymphocytes are triggered to make antibodies (also called immunoglobulins). These proteins lock onto specific antigens.

A straw is placed inside a rectangular box that is 3 inches by 5 inches by 1 inches, as
shown. If the straw fits exactly into the box diagonally from the bottom left corner to
the top right back corner, how long is the straw? Leave your answer in simplest
radical form.
The length of the straw will be 5.91607 inches long in radical form.
What is Length of diagonal in cuboid?If a cuboid has length = l units, breadth = b units, and height = h units, then we can evaluate the length of the diagonal of a cuboid using the formula
[tex]X^{2}= l^{2}+b^{2}+h^{2}[/tex]
As per the question the length of the straw is equal to length of the diagonal of Rectangular box.
l= 3 inch , b= 5 inch , h= 1 inch
Let us consider the length of the straw be 'x'.
As, Diagonal of Cuboid is,
[tex]X^{2}= l^{2}+b^{2}+h^{2}[/tex]
[tex]X^{2}= 3^{2}+5^{2}+1^{2}\\X^{2}= 9+25+1\\X^{2}= 35\\X= \sqrt{35}[/tex]
X= 5.91607 (in radical form)
Hence, the length of the straw will be 5.91607 inches.

Answer:
7.3 cm
Explanation:
Given a right angle triangle, In order to find the third side: Use Pythagoras Theorem: a² + b² = c²
Insert values:
x² + 8.9² = 11.5²
x² + 79.21 = 132.25
x² = 132.25 - 79.21 (subtract)
x² = 53.04
x = √53.04 (square root)
x = 7.28285 ≈ 7.3 (rounded to 1 decimal place)

Given the relation: {(1,2),(2,3),(-1,3),(2,5)}
Determine what two points cause the relation to not be a function? Explain why these points cause the relation to not be a function.
Answer: (2,3) and (2,5) cause the relation to not be a function
Explanation:
The input x = 2 leads to y = 3 and y = 5 at the same time for both points. A function is where any input x leads to exactly one y output only. So we'd need to get rid of one of those mentioned points to be able to have a function.
If you graphed the points on the same xy grid, then you'd see (2,3) and (2,5) vertically aligned. These two points cause the vertical line test to fail. This will give a visual indication we do not have a function.
Put another way, if x repeats itself then we don't have a function. The y value is allowed to repeat. So we could have something like (1,2) and (5,2) be part of a function.

In an experiment, 16 babies were asked to watch a climber attempt to ascend a hill. On two occasions, the baby witnesses the climber fail to make the climb. Then, the baby
witnesses either a helper toy push the climber up the hill, or a hinderer toy preventing the climber from making the ascent. The toys were shown to each baby in a random
fashion. A second part of this experiment showed the climber approach the helper toy, which is not a surprising action, and then the climber approached the hinderer toy,
which is a surprising action. The amount of time the baby watched the event was recorded. The mean difference in time spent watching the climber approach the hinderer
toy versus watching the climber approach the helper toy was 1.22 seconds with a standard deviation of 1.58 seconds. Complete parts a through c.
The test statistic based on the information will be 2.74 and the degree of freedom is 15.
How to calculate the test statistic?From the information given, the test statistic will be:

you need to make 6000g of potato cakes. the ratio of potato, cheese and onion is 9:2:1. per every 175g of cheese = £2.25. how much will all of the cheese cost?
Let
potato be 9x,cheese be 2x and onion be x
9x+2x+x=600012x=6000x=500Cheese
2(500)1000gTotal 175gs
100/1755.714Total cost
5.714(2.25)£12.85Answer:
£12.86 (nearest pence)
Step-by-step explanation:
Given ratio:
potato : cheese : onion = 9 : 2 : 1Sum the ratios:
⇒ 9 + 2 + 1 = 12
Divide the total weight by the sum of the ratios:
⇒ 6000 g ÷ 12 = 500
Multiply each ratio by 500 to find the amount of each ingredient needed to make 6000 g of potato cakes:
⇒ potato = 9 × 500 = 4500 g
⇒ cheese = 2 × 500 = 1000 g
⇒ onion = 1 × 500 = 500 g
If 175 g of cheese costs £2.25, then 1000 g of cheese costs:
⇒ (2.25 / 175) × 1000 = £12.86 (nearest pence)
