If you force the magnitude of the vector to stay the same, but increase the vertical component value, what happens to the horizontal component of the vector?
Answers
Answer:
The horizontal component reduces
Explanation:
The magnitude of a vector is found by taking the root of the sum of the squares of the components of the vector
Therefore, when the values of one of the components is increased, while the other components of the vector stay the same, the magnitude of the vector increases
In order to increase the value of one of the components of a vector and maintain the magnitude of the vector, the values of one or more of the other components must be reduced.
As such when the magnitude of the vector that has only a vertical and a horizontal component is forced to stay the same, and the vertical component is increased, the horizontal component must be reduced.
The increase in vertical component of the vector, causes a decrease in the horizontal component of the vector.
A vector can be represented in vertical and horizontal components.
[tex]V = V_x + V_y[/tex]
where;
[tex]V_x[/tex] is the horizontal component of the vector[tex]V_y[/tex] is the vertical component of the vector[tex]V = Vsin(\theta) \ + Vcos(90-\theta)[/tex]
From the formula above, as one component vector increases, the other component reduces.
Thus, the increase in vertical component of the vector, causes a decrease in the horizontal component of the vector.

Describe at least three ways our understanding of the atom has changed.
Answers
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.

Answers
Answer:Electrones
Explanation:Because its building up static
Answer:
B) Electrons
Explanation:
When William slides down the slide, the rubbing action between William and the slide causes electrons to be transferred to William and stored as a negative charge.
When he touches a piece of metal, the negative charge (i.e the build up of excess electrons), is released (discharged) into the metal causing what we know as a static shock.

Answers
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.

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.
Answers
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

his momentum at this point?
A. 359.3 kg.m/s
B. 105.6 kg.m/s
C. 211.2 kg-m/s
O D. 36.7 kg-m/s
Answers
The momentum of the cyclist and bicycle at this point is 211.2 kg·m/s, calculated by multiplying their combined mass (88 kg) by their velocity (2.4 m/s). The correct answer is C.
The momentum of an object is defined as the product of its mass and velocity. To find the momentum of the cyclist at this point, we can use the equation: momentum = mass × velocityFirst, let's find the mass of the cyclist and his bicycle. We are given that their combined mass is 88 kg. Next, we need to find the velocity of the cyclist. We are given that he reaches a speed of 2.4 m/s after 2 seconds, and that he accelerates at a rate of 1.2 m/s². We can use the equation of motion: velocity = initial velocity + acceleration × timeThe initial velocity is 0 m/s (since the cyclist starts from rest), the acceleration is 1.2 m/s², and the time is 2 seconds. Substituting these values into the equation, we get:velocity = 0 + 1.2 × 2 = 2.4 m/sFinally, we can calculate the momentum by multiplying the mass and velocity:
momentum = 88 kg × 2.4 m/s = 211.2 kg·m/sTherefore, the correct answer is C. 211.2 kg·m/s.

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.
