Independent, and inverse means if one variable increases then the other decreases, direct is when they both go up or down together.
Distance from the sun.
<span>The third law of planetary motion states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit</span>. The semi-major axis is the distance from the sun to the epicenter of the ellipse (which would be the planet in question). So, the revolutionary period is directly related to the distance of the planet from the sun.
1) How are particles in motion and temperature related?
Temperature is the measure of heat. The kinetic energy of particles in motion is determined by the temperature. The higher the temperature, the higher the kinetic energy of the particles (basically, the hotter it is the faster the particles move).
2) How does a thermometer work?
A thermometer measures the average kinetic energy of the particles around the thermometer. As seen in 1), the kinetic energy defines the temperature, so measuring the energy of the particles can show you the temperature of the object.
3) What are temperature scales, list them and give examples.
Temperature scales are pretty much systems with which we compare different temperatures. The three widely used temperature scales today are Fahrenheit, Celsius, and Kelvin. All three are used in different countries and mainly for different purposes. Fahrenheit is used only in the United States and a few other countries around the world, while Celsius is excepted by nearly the entire rest of the world. Kelvin is used primarily in the scientific setting.
4) Define volume.
Volume is pretty much the amount of three-dimensional space an object or substance takes up. For example, a liter is a unit of measurement of volume. A two-liter bottle of soda means it contains the amount of soda that fills up 2-liters worth of three-dimensional space.
I hope this helped.
<span>The primary reason a light bulb emits light is due to the heating of the resistance in the filament of the light bulb. In fact, the power dissipated in a resistor is given by
</span>
<span>where I is the current and R the resistance. The larger the resistance or the current in the resistor, the larger the power dissipated. Due to this dissipation of power, the temperature of the filament becomes very high, and the resistance becomes incandescent, emitting light.</span>
Answer:
5 feet
Explanation:
First lets imagine that the values are in meters and kg, to make it easier for me.
--------------------------------------------------------------------------------------------------------
The force created by the teacher is 120 × 5 = 600N.
--------------------------------------------------------------------------------------------------------
The force created by the 50 kg student is 50 × 8 = 400N
--------------------------------------------------------------------------------------------------------
The force that needs to be created by the 40 kg student is 600N - 400N = 200N.
To create that force that student needs to sit 200 ÷ 40 = 5m.
So the 40 lbs student is sitting 5 feet from the fulcrum.
