Homework Helper: Mass
http://dragon51188-homework-helper.blogspot.com/2007/03/mass.html
For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Monday, March 19, 2007. Mass is one of the basic ways of measuring things in science. Chemistry measures things in grams, physics likes using kilograms. Many people use mass and weight to mean the same thing, but they are different. Weight is actually a force and can change while mass stays the same. Subscribe to: Post Comments (Atom).

Homework Helper: Math Practice Problems #1
http://dragon51188-homework-helper.blogspot.com/2008/09/math-practice-problems-1.html
For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Tuesday, September 02, 2008. Math Practice Problems #1. While out roaming the Internet, I sometimes encounter people who need help with their homework, so I had the idea of collecting their questions and posting them here. If the polynomial 4-7x 2x. Has degree a, leading coefficient b, and constant term c, then the value of. Well, the highest exponent is 3. And the answer is 15 .

For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Monday, November 20, 2006. Now we get to find where something lands after being launched, but first, there’re a couple new things to learn. That works for the up-and-down direction. You can get a time from that and use it to find the distance in the horizontal direction. I’ll explain what the new variables mean. s. Is the starting position, s. Is how far up or down it ends up, s.

Homework Helper: Tangent

For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Monday, September 01, 2008. Hello, everyone, I'm back from my year-long absence. I promised that I'd write about the tangent (tan) that went with sine and cosine. In trigonometry, so here goes. First, we take the same triangle we used for the sine and cosine. Let's use the same axes, too. Remember the "Toa" part of "SohCahToa"? Subscribe to: Post Comments (Atom). None, school sucks.

Homework Helper: Math Practice Problems #2
http://dragon51188-homework-helper.blogspot.com/2008/09/math-practice-problems-2.html
For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Thursday, September 25, 2008. Math Practice Problems #2. Today, I was asked this question:. Titan and Rhea are the two largest moons of Saturn. The ratio of of the surface area of Titan to the surface area of Rhea is about 34:3. If the diameter of Rhea is about 1530km, what is the diameter of Titan? This one's pretty simple. We only need two formulae. Since there's a 4π.

Homework Helper: Sine and Cosine
http://dragon51188-homework-helper.blogspot.com/2006/11/sine-and-cosine.html
For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Monday, November 20, 2006. Before going on to the next post about acceleration, I need to explain sine (sin) and cosine (cos). First, let’s take a triangle. This one will do nicely. You need to have a standard set of directions, though, so let’s put the triangle on a set of horizontal and vertical axes. Back in trigonometry (or was it algebra? Subscribe to: Post Comments (Atom).

Homework Helper: Acceleration
http://dragon51188-homework-helper.blogspot.com/2006/11/acceleration.html
For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Wednesday, November 01, 2006. When it’s used in regular conversation, accelerat means to speed up. In science, though, it means a change in velocity. You can use it with numbers and direction to tell whethersomething is moving faster or slower in any direction. Acceleration is just how much the velocity changes every second. So your acceleration was -5m/s. W3C - HTML and CSS Help.

Homework Helper: Distance and Displacement
http://dragon51188-homework-helper.blogspot.com/2006/10/distance-and-displacement.html
For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Wednesday, October 11, 2006. In physics, there is a difference between distance travelled and displacement. Distance travelled is obvious. It’s just how much you travelled, like an odometer on a car. Displacement is simple, too. It’s how far you end up from where you started. Subscribe to: Post Comments (Atom). W3C - HTML and CSS Help. Toward the Future with Hope. None, school sucks.

Homework Helper: Force
http://dragon51188-homework-helper.blogspot.com/2007/03/force-is-push-or-pull-on-object.html
For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Monday, March 19, 2007. 8230;And here’s what it means: To find the force acting on an object, you multiply the mass of the object times its acceleration. That means force has a magnitude (size) and a direction. Yes, there’s a special unit for force, too. If you multiply the units for mass and acceleration, you get Kg•m/s. A force of 1 Newton is acting on it. W3C - HTML and CSS Help.

Homework Helper: Acceleration #5
http://dragon51188-homework-helper.blogspot.com/2007/04/acceleration-5.html
For those who need help with schoolwork. Feel free to ask a question, even if it's not about anything that's already posted. Thursday, April 26, 2007. Today, we get an artillery on a cliff above the same camp as last time. Osama was spotted through a window seated on the toilet in his outhouse 400 meters away and 100 meters down from our spot. This time, our artillery is better than the one we used last time, firing shells at 100m/s. The question is, how high do we aim it? You can see how I derived that.
