Answer: The answer is C. 298 K

Explanation:

The angle v with arrow makes with the positive direction of the x axis at   t = 9.00 s is -86.23° degrees from the +x axis.

One of the subatomic particles with mass is the electron. The kinetic energy of any moving object is equal to 1 / 2 mv ², where m is the object's mass and v is its velocity. Electron speed V = 1 / 2 mqv ² is an electromagnetic equation.

a) v with arrow(t) = dr with arrow/dt

                                = 2.00i + (-14.00t)j + 0k

b) v with arrow (t = 9.00) = 2.00i + (-14.00  9.00)j + 0k

                                 = 2.00i - 126.00j

c) the magnitude of v with arrow (t = 9.00)

                          = √(2.002 + (-126.00)2)

                                      = 126.00

d) tan(theta) = vy/vx

                               = -126.00/2.00

                              = -63.00,

θ = atan(-63.00)

                                  = -86.23° degrees.

So, the angle v with arrow makes with the positive direction of the x axis at

                        t = 9.00 s is -86.23 degrees from the +x axis.

Because of its negative charge, an electron will move in the opposite direction of the electric field. As a result, it will move to the left. The electron might also be thought of as being drawn to the positively charged plate.

Answer:

Centripetal Force Requirement

The Forbidden F-Word

Mathematics of Circular Motion

As mentioned earlier in this lesson, an object moving in a circle is experiencing an acceleration. Even if moving around the perimeter of the circle with a constant speed, there is still a change in velocity and subsequently an acceleration. This acceleration is directed towards the center of the circle. And in accord with Newton's second law of motion, an object which experiences an acceleration must also be experiencing a net force. The direction of the net force is in the same direction as the acceleration. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes referred to as the centripetal force requirement. The word centripetal (not to be confused with the F-word centrifugal) means center seeking. For object's moving in circular motion, there is a net force acting towards the center which causes the object to seek the center.

To understand the importance of a centripetal force, it is important to have a sturdy understanding of the Newton's first law of motion - the law of inertia. The law of inertia states that ...

... objects in motion tend to stay in motion with the same speed and the same direction unless acted upon by an unbalanced force.

According to Newton's first law of motion, it is the natural tendency of all moving objects to continue in motion in the same direction that they are moving ... unless some form of unbalanced force acts upon the object to deviate its motion from its straight-line path. Moving objects will tend to naturally travel in straight lines; an unbalanced force is only required to cause it to turn. Thus, the presence of an unbalanced force is required for objects to move in circles.

Explanation:

The work done on the Puck by the applied force from the most positive to the most negative is c, b, a respectively.

According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = ma

\(F= \frac{mv}{t}\)

The force applied to an object increases with increases in the velocity of the object.

In the given diagram, the resultant velocity of the puck is calculated as follows;

Figure a:

\(\Delta v = v_f -v_i\\\\\Delta v = 5 - 6 = - 1 \ m/s\)

Figure b:

\(v = \sqrt{4^2 + 3^2} \\\\v = 5 \ m/s\)

Figure c:

\(\Delta v = 4 - (-2)\\\\\Delta v = 6 \ m/s\)

Thus, the work done on the Puck by the applied force from the most positive to the most negative is c, b, a respectively.

To achieve total internal reflection, the minimum refractive index of the plastic must be at least 0.869 when a ray of light is incident at an angle of 61 degrees on the center of one side of the plastic slab in air.

The minimum refractive index of the plastic can be found , we need to consider the conditions for total internal reflection.

Total internal reflection occurs when the angle of incidence is greater than the critical angle, which is the angle at which the refracted ray is at a 90-degree angle to the normal.

In this scenario, the ray of light is incident on the plastic at an angle of 61 degrees. We can use Snell's law to relate the angle of incidence to the angle of refraction:

n1 * sin(angle of incidence) = n2 * sin(angle of refraction)

Here, n1 is the refractive index of air (approximately 1), and n2 is the refractive index of the plastic.

Since we want the light to be totally internally reflected, the angle of refraction will be 90 degrees. Thus, we have:

1 * sin(61 degrees) = n2 * sin(90 degrees)

Rearranging the equation, we get:

n2 = sin(61 degrees) / sin(90 degrees)

Calculating this expression, we find that n2 is approximately 0.869.

Therefore, the minimum refractive index of the plastic should be at least 0.869 to ensure total internal reflection in this scenario.

The correct options for the factors that contribute to the Earth's magnetic field, which protects us from solar wind, are option b. the liquid outer core and option f. the Earth's rotation.

The Earth's magnetic field is generated by the motion of molten iron and nickel in the liquid outer core of the Earth (Option b). This motion, known as convection, generates electric currents that produce the magnetic field.

The Earth's rotation (Option f) also plays a significant role. The rotation of the Earth causes the convection currents in the liquid outer core to circulate and amplify the magnetic field, creating a dynamo effect.

The Earth's revolution (Option a) around the Sun and its tilt on its axis (Option c) are not directly responsible for the generation of the Earth's magnetic field. They are factors that influence climate and seasons on Earth but do not contribute to the magnetic field.

The seasons (Option d) are related to the Earth's axial tilt and its orbit around the Sun but are not directly connected to the generation of the magnetic field.

The moment when the coffee filter fall from the upward, it is in the equilibrium.

A coffee filter is falling through the air after being released from a specific height. The filter accelerates for a time and rotates a bit so that the bottom of the filter is facing down, but then reaches a terminal velocity. Now, it is continuing to fall at a constant speed without tipping or rotating. When it is falling from the height, the gravitational force acting on it and the air resistance acting on it balances out each other. Then there is no net force on the coffee filter that is acting on it either ways. When the filter is going downwards many are the forces they are working on it, but when it is going down all the forces acting on it got cancel out and only the net forces acting on majorly cancel each other effect and it nullifies them and their effect and we got a net zero force on it.

a) Currently connected Al Barakah nuclear power units will contribute 24.5 million MWh annually to the national grid.

b) Gas saved due to the operation of the first two nuclear reactors is 12.8 million m3.

c) The amount of CO2 that will be removed from the atmosphere as a result of bringing the four units of Al Barakah nuclear power station online is 21.9 million tonnes

.Explanation:

a) How much of annual energy will the currently connected Al Barakah nuclear power units contribute to the national grid?

The capacity of the first nuclear power plant is 1400 MW and it is now online. There are two units of 1400 MW each, and one is already online. Therefore, total capacity of the connected nuclear generated power is 2800 MW. The annual energy will be:Annual energy = Connected nuclear generated power × hours in a year= 2800 MW × 8760 hrs= 24.5 million MWhb) Assume that gas turbines consume 0.21 m3 of equivalent natural gas for every 1kWh of electricity produced, how much of gas (in m3) will be saved due to the operation of the first two nuclear reactors (units)?The energy generated by the first two nuclear reactors in a year is 24.5 million MWh. To generate the same amount of energy using gas turbines, the amount of gas required is:Energy generated by gas turbines = Energy generated by nuclear plants= 24.5 million MWhThis amount of energy will be generated by the following amount of gas:Energy generated by gas turbines = Amount of gas × 0.21 m3/kWh= Amount of gas = Energy generated by gas turbines / 0.21 m3/kWh= 24.5 million MWh / 0.21 m3/kWh= 11,761 million m3Therefore, the gas saved due to the operation of the first two nuclear reactors is:Gas saved = Gas required to generate the same amount of energy by gas turbines – Amount of gas required by nuclear reactors= 11,761 million m3 – 0= 11,761 million m3c) How many tonnes of CO2 will be removed from the atmosphere as a result of bringing the four units of Al Barakah nuclear power station online?The carbon dioxide emission rate of a gas-fired turbine is 0.52 kg CO2/kWh, and the carbon dioxide emission rate of a nuclear power plant is 0.00 kg CO2/kWh.

Answer: Force

In physical science, a force is something that acts on an object by pushing or pulling it. If the force is strong enough, it changes the position or shape of the object. Forces such as friction, air resistance and simple physical contact touch the object directly, while forces like gravity, magnetism and electrostatics act on the object from a distance. Force is a vector quantity, meaning you can measure both its strength and its direction. The formula to find the measure of a force is force = mass times acceleration, written as f = ma.

Velocity

The faster something is moving, the higher its velocity.

When an object is moving, one way to measure how fast it is moving is by finding its velocity, which is the rate at which it is changing position. Like force, velocity is a vector quantity, so it includes direction. To find the average velocity of an object, divide the change in its position by the time the movement took, and state its direction. For example, if a car is driving north and in one hour's time it travels 30 miles, its velocity is 30 miles per hour, north.
