Answer: B. Vector rules
Explanation:
To solve this we must be knowing each and every concept related to velocity. Therefore, the correct option is option B among all the given options.
What is velocity?Velocity refers to a vector assessment of an object's rate of motion and direction of motion. As a result, in order to calculate velocity using this definition, we must be familiar with both magnitude and direction.
It determines how quickly or slowly something moves. Consider the following scenario: two moving objects. If both items are going in the same direction, it is simple to determine which one is moving faster. However, judging which item is quicker is difficult when they are traveling in different directions. Vector rules is used for combining velocities.
Therefore, the correct option is option B among all the given options. Vector rules is used for combining velocities.

What is a graph?A graph is a visual depiction of statistical data or a logical relationship between variables. Graphs serve a predictive purpose because they have the virtue of displaying broad trends in the mathematical behavior of data. However, as just approximations, they may be incorrect and occasionally deceptive.
Most graphs have two axes, with the axis denoting a set of independent variables and the vertical axis denoting a set of dependent variables. The most typical graph is indeed a broken-line chart, where the regression coefficient is typically a factor of duration.
In the second graph the speed of every student is represented accurately, therefore the second graph is correct.

Explanation:
Sarah is asked to sort out the list of ions and ionic compounds. How can Sarah differentiate between the ions and ionic compounds? Ions have a positive or negative charge, but an ionic compound's overall charge is zero. Ions have no charge, but ionic compounds have a positive charge. Ions have no charge, but ionic compounds have a negative charge. Ions have a positive or negative charge, but an ionic compound's overall charge is negative.
Answer:
Ions have a positive or negative charge, but an ionic compound's overall charge is zero.
Explanation:
Ionic compounds are compounds said to contain ions, which are atoms that have either lost electrons to be POSITIVELY CHARGED or gained electrons to be NEGATIVELY CHARGED. The negatively charged ions are called ANIONS while the positively charged ions are called CATIONS.
These cations (+ ions) and anions (- ions) make up ionic compounds in such a way that they give the ionic compound a net charge of ZERO. This is because the charges of the opposite ions that make up the ionic conpound are equal. For example, in the ionic compound CaCl2;
Ca is a cation with charge +2
Cl is an anion with charge -1, 2 atoms make a net charge of -2
When these two ions combine, they cancel out each other to form an ionic compound, CaCl2, with net charge 0 or neutral
Answer:
The answer is
A. Ions have a positive or negative charge, but an ionic compound's overall charge is zero

4. Vector A is 7.00 units in length and points along the positive x-axis. Vector B is 5.00 units in length and points along the negative x-axis. find the magnitude and direction of A+2B 1 point
Answer:
Since the two vectors form a right angle, no components need to be found for the resultant vector - we already have them!
Vector R's x-component = 3.00 units
Vector R's y-component = 4.00 units
To solve for the magnitude of the displacement, use the distance formula: Square Root of [(3)^2 + (4)^2], which equals 5 units.
To solve for the direction of the displacement, plug in -4 (remember where it was pointing) for y and 3 for x. Tan-1(-4/3) = -53.13°, or 53.13° south of east.Please Mark as Brilliant

Divers at Acapulco dive from a cliff that is 61 m high. If the rocks below the cliff extend outward for 23 m, what is the minimum horizontal velocity a diver must have to clear them?
Answer:6.5 m/s
Explanation:Look at the image I believe that's the answer
The horizontal velocity of the diver would be 6.522 meters / seconds.
What are the three equations of motion?There are three equations of motion given by Newton
v = u + at
S = ut + 1/2×a×t²
v² - u² = 2×a×s
As given in the problem, Divers at Acapulco dive from a cliff that is 61 m high. If the rocks below the cliff extend outward for 23 m, then we have to find out the minimum horizontal velocity a diver must have to clear them,
By using the second equation of motion in the vertical direction,
s = ut + 0.5at²
61 = 0+ 0.5×(-9.81) ×t²
t² = 61/(0.5×9.81)
= 12.43
t = 3.526 seconds
The horizontal velocity of the diver = 23 meters / 3.526 seconds
=6.522 meters / seconds
Thus, the horizontal velocity of the diver would be 6.522 meters/second.

Describe at least three ways our understanding of the atom has changed.
Answer:
The first model of the atom was developed by JJ Thomson in 1904, who thought that atoms were composed purely of negatively charged electrons.
This theory was then disproved by Ernest Rutherford and the gold foil experiment in 1911, where Rutherford shot alpha particles at gold foil, and noticed that some went through and some bounced back, implying the existence of a positive nucleus.
In 1926, the Austrian physicist Erwin Schrödinger created a quantum mechanical model of the atom by combining the equations for the behavior of waves with the de Broglie equation to generate a mathematical model for the distribution of electrons in an atom.

Put the value into the formula
[tex]h=20\times3-\dfrac{1}{2}\times9.8\times3^2[/tex]
[tex]h=15.9\ m[/tex]
At t=4 sec
We need to calculate the velocity and height
Using equation of motion
[tex]v=u-gt[/tex]
Put the value into th formula
[tex]v=20-9.8\times4[/tex]
[tex]v=-19.2\ m/s[/tex]
Negative sign shows the opposite direction of motion
