First of all, what is displacement?

It is the minimum distance covered by a moving object between initial and final position.

Since the boomerang comes back to its original position, the displacement is 0!

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 = 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.

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.

Answer:

Sling Psychrometer

Explanation:

A sling psychrometer measures relative humidity through the process of evaporation. It contains two thermometers. The cloth around one of the thermometers is wetted and slung around in the air so the moisture evaporates, which has a cooling effect. The relative humidity is then calculated using the difference in temperature for the two thermometers.

Answer:

The speed and height at 0 sec are 20 m/s and 0 m.

The speed and height at 1 sec are 10.2 m/s and 15.1 m.

The speed and height at 2 sec are 0.4 m/s and 20.4 m.

The speed and height at 3 sec are 9.4 m/s and 15.9 m.

The speed and height at 4 sec are 19.2 m/s and 1.6 m.

Explanation:

Given that,

Initial speed = 20 m/s

Suppose, given time in charge are t= 0, 1, 2, 3, 4 sec

At t=0 sec,

We need to calculate the velocity and height

Using equation of motion

[tex]v=u-gt[/tex]

Put the value into the formula

[tex]v=20-9.8\times0[/tex]

[tex]v=20\ m/s[/tex]

Now, using second equation of motion

[tex]h=ut-\dfrac{1}{2}gt^2[/tex]

Put the value into the formula

[tex]h=20\times 0-\dfrac{1}{2}\times9.8\times0[/tex]

[tex]h=0\ m[/tex]

At t=1 sec,

We need to calculate the velocity and height

Using equation of motion

[tex]v=u-gt[/tex]

Put the value into the formula

[tex]v=20-9.8\times1[/tex]

[tex]v=10.2\ m/s[/tex]

Now, using second equation of motion

[tex]h=ut-\dfrac{1}{2}gt^2[/tex]

Put the value into the formula

[tex]h=20\times1-\dfrac{1}{2}\times9.8\times1^2[/tex]

[tex]h=15.1\ m[/tex]

At t=2 sec,

We need to calculate the velocity and height

Using equation of motion

[tex]v=u-gt[/tex]

Put the value into the formula

[tex]v=20-9.8\times2[/tex]

[tex]v=0.4\ m/s[/tex]

Now, using second equation of motion

[tex]h=ut-\dfrac{1}{2}gt^2[/tex]

Put the value into the formula

[tex]h=20\times2-\dfrac{1}{2}\times9.8\times2^2[/tex]

[tex]h=20.4\ m[/tex]

At t=3 sec,

We need to calculate the velocity and height

Using equation of motion

[tex]v=u-gt[/tex]

Put the value into the formula

[tex]v=20-9.8\times3[/tex]

[tex]v=-9.4\ m/s[/tex]

Negative sign shows the opposite direction of motion

Now, using second equation of motion

[tex]h=ut-\dfrac{1}{2}gt^2[/tex]

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

Now, using second equation of motion

[tex]h=ut-\dfrac{1}{2}gt^2[/tex]

Put the value into the formula

[tex]h=20\times4-\dfrac{1}{2}\times9.8\times4^2[/tex]

[tex]h=1.6\ m[/tex]

So, The ball has hit the ground at 5 sec.

Hence, The speed and height at 0 sec are 20 m/s and 0 m.

The speed and height at 1 sec are 10.2 m/s and 15.1 m.

The speed and height at 2 sec are 0.4 m/s and 20.4 m.

The speed and height at 3 sec are 9.4 m/s and 15.9 m.

The speed and height at 4 sec are 19.2 m/s and 1.6 m.

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.

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.

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.

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

In a gym the students raced with each other and teacher is recording everyone's speed than the second graph is representing correctly.

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.
