What is Pythagoras theorem?
In mathematics, the Pythagorean Theorem or Pythagorean Theorem is the fundamental relationship in Euclidean geometry between the three sides of a right triangle. It states that the area of a square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation for the lengths of sides a, b and hypotenuse c and is often called the Pythagorean equation.
This theorem is named after the Greek philosopher Pythagoras, who lived around 570 BC. he was born This theorem has been proven countless times in many different ways. The proofs vary and include both geometric and algebraic proofs, some thousands of years old.
If the Euclidean space is expressed in the Cartesian coordinate system of analytic geometry, the Euclidean distance satisfies the Pythagorean relation. That is, the square of the distance between two points is equal to the sum of the squares of the differences in each coordinate between the points.

as a copper wire is heated, its length increases by 0.1%. what is the change in temperature of the wire? (copper
The change in temperature of the wire is 60.2°C.
What is the change in the temperature of the copper?Near room temperature, the temperature coefficient of copper is +0.393% per degree C. It follows that the resistance will rise by 0.393% if the temperature rises by 1°C.The only way to do so would be to attach a copper plate to the wire and take its temperature in order to use an infrared thermometer to measure it (the laser only shows where you are pointing it). That would provide results almost instantly because copper is such a good heat conductor.Increasing temperature causes silicon's resistance to decrease, whereas doing so causes copper's resistance to rise. As copper warms up, the vibrations of the atoms scatter more conduction electrons.Learn more about change in the temperature refer to :

Stars emit different wavelengths of visible light due to their different temperatures. How does this phenomenon support the particle model of light?.
The particle model of light states that light is composed of discrete particles called photons.
What is photon?
The electromagnetic force is carried by a photon, an elementary particle which is a quantum of a electromagnetic field and includes electromagnetic radiation like light and radio waves. Due to their lack of mass, photons always travel at the speed of light in a vacuum, which is 299792458 m/s (or 186,282 mi/s). The photon is a member of the boson family. Photons exhibit wave-particle duality, with their behaviour exhibiting characteristics of both waves and particles. Like other subatomic particles, photons have been best explained by quantum mechanics. In the first two decades of the twentieth century, Albert Einstein developed the modern photon theory, building on the work of Max Planck.
The varying wavelengths of visible light emitted by stars are evidence of the particle nature of light, since different temperatures of stars result in different amounts of energy being released in the form of photons, which each have a different frequency and energy level. This phenomenon supports the particle model of light because it demonstrates that light is composed of distinct particles with different energies.

Highest -- Mercury, Earth, Mars, Jupiter, Neptune -- Lowest
Notice that, for these five planets, temperature correlates with distance from the Sun: the closer to the Sun, the hotter the planet. Remember, however, that this is not always the case, because a planet’s temperature also depends on its reflectivity and on the strength of its greenhouse effect (if any). For example, the greenhouse effect gives Venus a higher average temperature than Mercury, even though Venus is nearly twice as far from the Sun.

What's the average face temperature?
Planetary face temperatures range from over 400 °C on Mercury and Venus to below-200 °C on distant globes. The factors that determine temperature are the complex balance of heat entered and lost.
Thus, for these five globes, temperature correlates with distance from the Sun. The near to the sun, the hotter the earth. Note, still, that this isn't always the case, as the earth's temperature also depends on its reflectance and the strength of the greenhouse effect( if present).

A capacitor, because it has the greatest reactance at frequency f = 0 Hz.
A capacitor is a device that stores electrical energy in an electric field through the accumulation of electrical charges on two nearby surfaces insulated from each other. It has two terminals and is a passive electrical component. Charges flow through the capacitor when it is supplied with electricity, but this flow is blocked by the insulation between the metal plates. Since the capacitor's electrode plates are separated by an insulator (air or dielectric), no direct current can flow unless the insulator decays. In other words, a capacitor blocks direct current. When we connect a capacitor across an AC power source, it starts charging and discharging continuously due to the continuous change in the supply voltage. Capacitors do not store charge.

The speed of the given point on earth's surface is 428 m/s
Speed of point on earth's surface:A point located 1/4 of the length of the arc between the equator and the pole has an angle:
(1/4) × 90° = 22.5°
Since the arc angle of the line joining the equator and the pole is 90°
So the angle between the line joining the center and the given point, and the line joining center and the pole is Φ = 90° - 22.5° = 67.5°
Now,
Sin Φ = (radius of the point)/(radius of the earth)
Sin 67.5 = radius of the point/(6.37 × 10⁶)
Radius of the point:
r = 6.37 × 10⁶ × 0.9239 = 5.885 × 10⁶ m
Speed of the point on the globe is v = 2πr/(24 hours)
2πr = 2π × 5.885 × 10⁶ = 3.6977 × 10⁷ m

The equations that result from this 10T1 = 3700 or T1 = 370N and T2 = 130N.
What is equation?
In a mathematical equation, the equals sign is used to express that two expressions are equal. The meanings of the word equation as well as its cognates in those other languages can vary slightly. For instance, in French, an equation is defined as having one or even more variables, whereas in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign.
Finding the values for the variables that result in the equality is the first step in solving an equation with variables. The unknown variables are also known as the variables whereby the equation must be solved, and the unknown variable values that satisfy the equality are known as the equation's solutions.
Assume that T1 represents the tension inside the rope closest to the 400N person, and T2 represents the tension in another rope. T1 + T2 = 500N for translational equilibrium. The clockwise and counterclockwise torques about the beam's centre must be equal for there to be rotational equilibrium: 5T1 = 5T2 + 1200. These two equations can be combined to produce the following result:
T1 + T2 = 500
5T1 = 5T2 + 1200 or
T1 + T2 = 500
5T1 - 5T2 = 1200
multiply both sides of the first equation by 5, add the resulting equations to get 10T1 = 3700 or T1 = 370N and T2 = 130N.

when doing a chin-uo, a student lifts her 50.0 kg body a distance of .3 meters in 2 seconds. what is the power delivered by the student's biceps?
The Power provided by the student's biceps is 7.5 J/s.
What is power?The amount of energy transferred or converted per unit time is referred to as power. The watt is the unit of power in the International System of Units, equal to one joule per second. Power is sometimes referred to as activity in older works. A scalar quantity is power.The rate at which work is completed is referred to as power. Rate means per unit of time in this context. Power is calculated by dividing the amount of work done by the amount of time it took to complete the work.Given,
Mass = 50kg
Distance = 0.3 meters
Time = 2 seconds
W = fd
P = W/(t₂ - t₁)
To find work
W = (50kg)(0.3m)
W = 15J
To find power.
P = 15J / 2 - 0
P = 15J / 2
P = 7.5 J/s
Therefor the power is 7.5J/s

a suitcase is hanging straight down from your hand as you ride an escalator. your hand exerts a force on the suitcase, and this force does work. this work is
The work is positive when you ride up the escalator and negative when you ride down the escalator.
What is work?
Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement. In its simplest form, it equals the product of the force's magnitude and the distance traveled for a constant force directed in the same direction as the motion.
So, work done is positive when you ride up the escalator and negative when you ride down the escalator.

the following measurements from yaw marks left at the scene of an accident were taken by law enforcement officers. using a 31-ft length chord, the middle ordinate measured approximately 3 ft. the drag factor for the road surface is 1.02. a. determine the radius of the yaw mark to the nearest tenth of a foot. fill in the blank 1 41.5 b. determine the minimum speed that the car was going when the skid occurred to the nearest tenth.
The minimum speed of the car is 11.1634 mph and the radius of the yaw mark is 11.2 ft.
Yaw marks are always curved. They are, initiated by a steering input. They're what's left from a tire that is still rolling but is simultaneously sliding laterally.
The radius of the yaw mark to the nearest tenth of a foot = r
The minimum speed = s
Length of the chord = c = 31 ft
Middle ordinate = m = 3 ft
Drag factor = f = 1.02
The formula for determining radius from a chord and middle ordinate is =
= r² = (c² / 8 x m) + (m / 2)
= r² = (31² / 8 x 3) + (3 / 2)
= r² = 41.541
= r = 11.2 ft
(b) Now minimum speed = s
= s = √(15 X f X r)
= s = √ (15 X 1.02 X 11.2)
= s = 11.1634 mph

if the charge on q1 is doubled, assuming that charge of q2 and the distance of r stay the same, what will happen to the force between the two charges? (3 points)
If the charge on q1 is doubled the force becomes 4 times its initial value.
The charge of each object has a direct impact on electrostatic force. Therefore, the force will increases if the charge of one object is doubled.
The square of the distance between the two charges has an inverse relationship with the force's size. As a result, when the gap between two charges is doubled, the attraction or repulsion weakens and drops to one-fourth of its initial strength.
Since, we know
F = (k×q1×q2)/r²
When the charges are doubled, we have :
F' = (k × 2q1 × 2q2)/r²
F' = 4 (k×q1×q2)/r²
Thus,
F' = 4F
Hence, the force becomes 4 times its initial value.
