Answer:
wind power can be tracked back to sunlight since sunlight is one of the causes of moving air which is wind .
High temperature causes air to expand causing it to spread over a wider area decreasing it's pressure compared to places of lower temperature which causes air to contract causing a concentration of air molecules which increases its pressure . This two processes causes a pressure difference which leads to movement of air (wind) whose energy can be used to generate wind power.

A particle moving on the x-axis experiences a force given by Fx=qx2, where q is a constant. How much work is done on the particle as it moves from x=0 to x=d? Express your answer in terms of some or all of the variables q and d.
The work done on the particle as it moves from x=0 to x=d is qd^3/3 when a particle moving on the x-axis experiences a force given by Fx=qx2, where q is a constant.
Given force is Fx =qx^2
As particle moves from x = 0 to x = d the work done on the particle by using force Fx is as follows
By integration W = ∫Fxdx
W = ∫qx^2dx
W = (qx^3/3) from 0 to d
W = q/3(d^3 - 0)
W = qd^3/3
hence the work done by particle as it moves from x= 0 to x = 3 is qd^3/3

mechanical energy is select one because the roller coaster select one energy due to friction and air resistance as it travels down the track.State True or False your answer:
a. True
b. False
True, Mechanical energy is chosen because the roller coaster chooses one energy owing to friction and air resistance as it travels down the track.
what is friction ?
When we throw a ball on the ground, it starts moving with a certain speed. But ideally there would be no force acting in the direction of motion and according to Newton's first law the ball would keep rolling, but this doesn't happen. Instead, the ball stops after traveling a certain distance, so a force must be applied to it. We call this force "friction".
Friction provides the traction needed to walk without slipping. Friction is useful in most cases. However, they also offer a major countermeasure to movement. In addition, about 20% of car engine power is consumed to overcome friction in moving parts. In the next section, we take a look at some of these factors.

Using travel time , the distance of wave to epicenter is 7.5 x 10¹⁰m.
Dr. Robert Butler briefly described how to use seismic travel time curves. You can observe P- and S-wave arrivals on a seismogram and calculate how far the earthquake was from your station. A travel time curve is a plot of arrival times, usually of a P or S wave, recorded at various points as a function of distance from the seismic source. Seismic velocities in the ground can be calculated from the slopes of the resulting curves.A seismic wave traveling through an isotropic homogeneous medium will propagate at a constant speed. Thus, the time required for a seismic wave to travel from source to receiver in a homogeneous earth layer with velocity is simply given by the formula t=d/v , where is the distance traveled in the layer. In a seismic survey, we measure the travel times between the source and the receiver and use this data to estimate the properties of the subsurface. Basic seismic interpretation methods assume that the Earth is composed of a series of uniform layers and attempt to calculate the thicknesses, velocities, and sometimes dips of each layer. We will discuss specific techniques for calculating layer thicknesses and velocities in the reflection and refraction survey sections.D=vt

a block of wood has specific gravity 0.80. when placed in water, what percent of the volume of the wood is above the surface?
20% of the total volume of a wood is above the surface.
Explain the term specific gravity?Specific gravity, also referred to as relative density, is a measurement of a substance's density in relation to water's density.The specific gravity may be calculated by dividing the substance's weight in grams by its volume in cc.An individual block of wood has a specific gravity of 0.80.
The ratio of the a material's density compared to that of a standard substance is its specific gravity, sometimes referred to as relative density.The term "buoyancy" refers to the upward force a fluid applies to a submerged item in a gravitational field.When an object is submerged in a fluid, the pressure applied to its bottom surface is greater than the pressure applied to its top surface because pressure in fluids increases with depth.Thus, 20% of the total volume of a wood is above the surface.

A magnetic field is a vector field that explains the magnetic influence on electrically charged objects in motion, electric currents, magnetic materials,[1]: [2]. A force perpendicular to the magnetic field and its own velocity acts on a moving charge in a magnetic field. [1]: ch13 [3]: 278 The magnetic field of a permanent magnet attracts or repels other magnets and pulls on ferromagnetic materials like iron. In addition, three more magnetic effects—paramagnetism, diamagnetism, and antiferromagnetism—exert minute forces on "nonmagnetic" materials in a nonuniform magnetic field, however these forces are often so minute that can only be measured by laboratory apparatus

The Moon does not crash into Earth because: its in Earth's gravitational field the net force on it is zero it is beyond the main pull of Earth's gravity its being pulled by the Sun as well as by Earth none of the above
It is freely falling but it has a high tangential velocity.
The correct answer is D.
Is the net force on the moon zero?
There cannot be zero net force acting on the Moon. There will be no circular orbit since there will be no net force acting on the Moon. The motion will be carried out by the Moon.
Why does the moon not have a gravitational pull?
The gravity at the Moon's surface is about 1/6th as strong as that at Earth, or 1.6 meters per second every second. The Moon's surface gravity is weaker because it has a smaller mass than Earth.

what device in a laser printer provides voltages to the corona wires? group of answer choices acps dcps hvps corona assembly
HVPS is the device in a laser printer provides voltages to the corona wires.They operate by positively charging a drum with a heated wire.
which is subsequently passed over by a laser that reverses the charge where it lands. The picture or text that will be printed is represented by the portions of the drum that are now negatively charged.The toner particles adhere to the negatively charged regions of the drum when a toner roller is moved over it. Electrical stimulation known as high-voltage pulsed stimulation (HVPS) is used to maintain and extend range of motion, avoid or delay muscular spasm, and retrain muscles..In a corona discharge, the neutral fluid, generally air, is ionized to produce an area of plasma surrounding the electrode, which allows a current to flow from the electrode with a high potential into the plasma-filled region.
