		<title>Physics projectile formula</title>
		<description><![CDATA[	A 0.11 kg ball is thrown straight up into the air with an initial velocity of 26 m/s
Find the momentum of the ball halfway to its maximum height on the way up.
	V0 = 26 m/s
g=9.8 m/s^2
	Max Height = V^2/2g
= 26^2 / 2*9.8
= 676 /19.6
= 34.489 meters
	Halfway up is 1/2 this number or 17.2445 meters
	Use the [...]]]></description>

		<title>Measure of voltage</title>
		<description><![CDATA[	How do you measure voltage in a circuit?
	Yes, you need to use a voltmeter or a multimeter with a voltage scale.
	Voltage is always measured with respect to 2 points in an electrical  circuit.
	Most  DC circuits use a common output of the power supply(usually the negative) for one of the points and call this [...]]]></description>

		<title>Capacitor circuits for energy storage?</title>
		<description><![CDATA[	If you have an Ultracapacitor with the below specs&#8230;
	Boostcap® Ultracapacitor
3000.0 Farad ± 20%; 2.7V
How many would you need to store 1KWH of energy?  ( 1,000 watts for an hour)
	The energy in Joules stored in a  capacitor can be calculated with the following formula
	E=(1/2) C V^2
	for C=3000F  V=2.7 Volts
	E=10935 Joules
	1Kwh = 3,600,000 Joules
	Therefore [...]]]></description>

		<title>Gravitational Potential Energy</title>
		<description><![CDATA[	A total of 10^4 kg of water per second flows over a waterfall 25m high!
If half of the power this flow  could be converted into electricity, how many 100W light bulbs could be supplied?
	This is a classic gravitational potential energy problem where we are asked for electrical power.
	The formula for the potential energy of [...]]]></description>

		<title>Elastic collision with the earth</title>
		<description><![CDATA[	A 500g rubber ball is dropped from a height of 10m and undergoes a perfectly elastic collision with the earth.
	(a) What is the Earth&#8217;s velocity after the collision, assuming the Earth is at rest just before the collision.
(b) How many years would it take the Earth to move 1.0mm at this speed?
	Well, the second assumption [...]]]></description>

		<title>Bcd seven segment driver control pic</title>
		<description><![CDATA[	I&#8217;m making an encoder and have to add a PIC to transfer the binary result to BCD-to-7 segment encoder. However, i don&#8217;t know how to program a PIC.
	Try this site:
 BCD  to 7 segment with a PIC microcontroller
	This site also claims to have the code you need as  part of a frequency counter [...]]]></description>

		<title>Mutual inductance in parallel</title>
		<description><![CDATA[	Two inductors having inductances L1= 5H and L2=2H and are connected in parallel. The mutual inductance M between the two inductors is 1H. Determine the equivalent inductance (in H) for this system.
	With mutual inductance the combined inductance is more complicated to calculate
	M=1H
	1/Ltotal =( L1 + L2 - 2(M)) / (L1L2 - M^2)
1/Ltotal = (7-2) / [...]]]></description>

		<title>Archimedes Principle for kids</title>
		<description><![CDATA[	What is the connection between people putting bricks in their toilets and Archimedes principle?
	Archimedes&#8217; principle is better known as the law of buoyancy.
It states:
Something submerged(partially or fully) in water experiences a force that tries to push it up (and out of the water).
	The amount of that force is exactly equal to the WEIGHT of the [...]]]></description>

		<title>Ozone and Greenhouse</title>
		<description><![CDATA[	What is the relationship between the ozone layer and greenhouse gases?
	The ozone layer and greenhouse gases are not directly related.
	The ozone layer is an area in the atmosphere where more ozone (also known as O3) compared to regular oxygen (O2) collects.
The Ozone layer is very good at blocking Ultraviolet light from the Sun from reaching [...]]]></description>

		<title>What is a diode?</title>
		<description><![CDATA[	The primary purpose of diodes is to allow electrical current to flow in only one direction.
	The primary purpose for power diodes is as components of power supplies that are used to convert AC (Alternating Current) line voltage (from the wall socket) into DC (Direct Current) to power an electronic device.
	Diodes are typically rated based on [...]]]></description>
