Student is attempting to hit a target 4 meters from the edge of the desk that is 1.4 m tall marble rules of a table horizontally as shown below according to the above information in diagram what velocity must a marble have to strike the target?

Answers

Answer:

The correct option is;

7.49 m/s

Explanation:

The time it takes the marble to fall vertically is given by the equation

s = u·t + 1/2·g·t²

Where;

s = The height of the table = 1.4 m

u = The initial vertical velocity = 0 (The marble is given only an initial horizontal push (velocity))

g = The acceleration due to gravity = 9.81 m/s²

t = The time it takes the marble to reach the ground 1.4 m below

Plugging in the values. gives;

1.4 = 0×t + 1/2 × 9.81 × t²

∴ t² = 1.4/(1/2 × 9.81) ≈ 0.28542 s²

t = √0.28542 ≈ 0.5342s

The horizontal range the marble is to cover in the approximately 1.87 seconds before it reaches the ground = 4 meters

Therefore, the velocity that allows the marble to reach 4 meters in 1.87 seconds is give as follows;

Velocity = Distance/Time = 4 m/(0.5342 s) ≈ 7.49 m/s

Therefore the horizontal velocity the marble must have to strike its target is approximately 7.49 m/s.

that causes the shock?
A atoms
B electrons
C. neutrons
D. protons

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.

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.

Answers

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.

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.

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.

A closed system consists of a pendulum that is swinging back and forth. If
the pendulum's kinetic energy decreases, what else must happen to the
energy of the system?
a
A. Its gravitational potential energy must decrease.
B. Its total mechanical energy must increase.
O C. Its total mechanical energy must decrease.
O D. Its gravitational potential energy must increase.

Answers

Answer:

The correct choice is D. Its gravitational potential energy must increase

Explanation:

Conservation of Mechanical Energy

The total amount of mechanical energy, in a closed system in the absence of dissipative forces like friction or air resistance, remains constant.

This means that energy cannot disappear or appear and that potential energy can become kinetic energy or vice versa.

In a closed system like a pendulum, two types of energies are considered: Gravitational potential (U) and kinetic (K). Thus, the sum of both energies must remain constant in time.

Suppose the pendulum is at a state where U=150 J, and K=350 J. The total mechanical energy is:

M = 150 J + 350 J = 500 J

If the kinetic energy decreases to a new value, say K = 200 J, then the gravitational potential must increase to compensate for this new condition, that is: U = 300 J

The correct choice is D. Its gravitational potential energy must increase

Taking into account the definition of kinetic, potencial and mechanical energy, the correct answer is option D:  If  the pendulum's kinetic energy decreases Its gravitational potential energy must increase.

Kinetic energy

Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.

Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.

Potential energy

On the other hand, potential energy is the energy that measures the ability of a system to perform work based on its position. In other words, this is the energy that a body has at a certain height above the ground.

Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the force of gravity.

Mechanical energy

Finally, mechanical energy is that which a body or a system obtains as a result of the speed of its movement or its specific position, and which is capable of producing mechanical work. Then:

Potential energy + kinetic energy = total mechanical energy

The principle of conservation of mechanical energy indicates that the mechanical energy of a body remains constant when all the forces acting on it are conservative (a force is conservative when the work it does on a body depends only on the initial and final points and not the path taken to get from one to the other.)

Therefore, if the potential energy decreases, the kinetic energy will increase. In the same way, if the kinetics decreases, the potential energy will increase.

This case

This principle can be applied in this case. The mechanical energy of the pendulum remains constant when all the forces acting on it are conservative.

So, the correct answer is option D:  If  the pendulum's kinetic energy decreases Its gravitational potential energy must increase.
