Question:I know that is the unit of measurement for heat, but what is it in reality?

Answers:It a measure of any form of energy, including heat, in MKS units. That means the primative units are expressed in meters, kilograms, and seconds, namely kg*m^2/s^2. 1 Joule, for example, is the kinetic energy K of mass M=1 kilogram traveling at speed V = 1 meter per second, times 1/2. The 1/2 is there because K=(1/2)MV^2. For heat, a 1 Watt heat source running for 1 second will release 1 Joule of heat, since Watt is the MKS unit of power.

Question:Duncan knows that it takes 36400cal of energy to heat a pint of water from room temperature to boiling. However, Duncan has prepared ramen noodles so many times he does not need to measure the water carefully. If he happens to heat 0.900pint of room-temperature water, how many kilojoules of heat energy will have been absorbed by the water at the moment it begins to boil?

Answers:0.900 pint @ 36,400 cal / pint = 32,760 calories 32,760 calories @ 4.184 joules / cal = 137,068 Joules 137,068 joules @ 1 kJ / 1000 Joules = your answer: 137 kJ

Question:I'm a sophomore in college. English major, want to combine with a double major in philosophy SATs: 1900/2400 (2007) CR- 600/Math-580/Writing-720 19 years old, Hispanic American Originally attended a Tier 1 Liberal Arts College in NY for 2008-2009. (GPA 3.6) Now attend a community college in NJ. ECs: Editor on my school's newspaper, Varsity Division I Tennis (Last year), Sociology Club, Philosophy Club Recommendations: Strong from my two teachers at my previous school. Former School Courses and grades World Literature I- B+ Reflective Tutorial- B+ (writing intensive college experience course) Script Analysis- A Political Philosophy- B Honors Macroeconomics- B+ Microeconomics- A- Financial Accounting I- A Intro to Psychology- A Computer Computency Fundamentals- A- Current Courses and Grades (Community College) General Chemistry I- B College Math I- A- Music Appreciation- A Intro to Shakespeare- A Western Civilization- A- Planned Courses Spring 2010 World Literature II Deviance and Social Control Development of the American Novel Topics in Literature Elementary French Criminology I think by the end of this year (next May), my cumulative college GPA will be about a 3.7, maybe a 3.8 if I'm lucky. Do I stand any chance? Would it be wise if I didn't get in to move to California, attend a CCC for one year and try again?

Answers:You better keep tabs on the cutbacks in the university system and the tuition hikes, since California has major financial problems. And no matter where you apply nowadays, out-of-state tuition may be cost prohibitive. The dollars have to make sense for you, but keep your options open, especially where you are a resident.

### Watt and Joule and Horsepower

Watt and Joule and HorsepowerAs we know, physical quantities of Power and Work are interconnected and are measured in watts and joules. Let us recall the physical meaning of these quantities. What exactly one watt or joule equals to? Watt is a unit of power of the SI system. It was named after its inventor, James Watt, the creator of the steam engine. This quantity is expressed in terms of other SI units. Since power is work per unit of time, watt can be expressed in terms of joules (unit of work) and seconds. Particularly, 1 watt equals 1 joule divided by one second. In its turn, joule can be expressed as the product of a Newton and a meter since it is the work done when moving the point of application of one-Newton force to one meter. Accordingly, watt can be expressed using these units: one watt equals one Newton multiplied by one meter and divided by a second. With regard to electricity, these quantities are defined differently. Joule is the work of a one-ampere electric current, which is performed as it passes through a 1-ohm resistance during one second. In its turn, electrical power is the quantity characterizing the rate of electricity transmission. It is expressed as the product of one volt and one ampere. One volt multiplied by one ampere is equal to one watt, or we can call it the power of a one-ampere current performing work at the voltage of one volt. Watts and kilowatts are used to measure power of different electric appliances, ie, the amount of energy they ...

### CalTech: Vectors P1

In elementary mathematics, physics, and engineering, an Euclidean vector , or simply a vector, is a geometric object that has both a magnitude (or length) and direction. A Euclidean vector is frequently represented by a line segment with a definite direction, or graphically as an arrow, connecting an initial point A with a terminal point B, AB A vector is what is needed to "carry" the point A to the point B; the Latin word vector means "one who carries".The magnitude of the vector is the distance between the two points and the direction refers to the direction of displacement from A to B. Many algebraic operations on real numbers such as addition, subtraction, multiplication, and negation have close analogues for vectors, operations which obey the familiar algebraic laws of commutativity, associativity, and distributivity. These operations and associated laws qualify Euclidean vectors as an example of the more generalized concept of vectors defined simply as elements of a vector space. Vectors play an important role in physics: velocity and acceleration of a moving object and forces acting on it are all described by vectors. Many other physical quantities can be usefully thought of as vectors. Although most of them do not represent distances (such as position or displacement), their magnitude and direction can be still represented by the length and direction of an arrow. The mathematical representation of a physical vector depends on the coordinate system used to describe it.
