Diagonals of a Rectangle??????
Why don't the diagonals of a rectangle bisect the angles? This may seem so easy, but I'm having difficult time understanding it....I'm confused because I know that the digonals of a rectangle bisect each other....so then why don't the angles do the same??? Pls...
a transformation question??? HELP PLS

Recently took a test and got one of the lowest scores I've ever gotten....theres no tutor avaliable and the prof isnt avaliable either....I'm trying to figure out the correct answers and how and which equations to use for each problem. I always have difficulty interpreting the questions and...
A rocket moves through space at 11,000 m/s. At this rate, how much time will be required to go to mars (78.3 x 10^6 km)?
i used t= d/v
and got 5.05 x 10^ -4
I'm not sure what i'm doing wrong. I cant get the correct answer
suggestions on any good Niels Bohr sites....
Taking a summer physical science class..and my presentation is on Niels Bohr....I wanted to know if there were any good sites anyone can point me to. THX :)
question when doing a simple investigative experiment.....
should such variables as mass be similar to each other? what would be the advatages? disadvantages?
I said that the masses really shouldnt be similar...you're trying to get a data spread and you want your masses to not be similar...
Light question.....difficulty finding answer....
My prof. just gave us about 6 questions on the last chapter of the summer semester, which is on light...he said we could try the question but if we couldnt get it right it was okay....I tried it anyways and I cannot get it....
At what range...
I'm doing a report that's due soon, and it was on an experiement...my hypothesis was that distance is directly related to time...we did an experiment w/ a hall cart and incline.....I said that it proved aristotle to be incorrect....i know his theories but how should i go forth explaining...
thx
The fahrenheit temp reading is 90 degrees on a hot summer day. What is the reading on the kelvin scale?
I know the kelvin scale is the absolute scale...i'm not sure how to tackle this problem or in other words what equation to use.

Question on 1 problem....graphical determinations
1) Why is a graphical determination of the avg velocity obtained from the slope of a best-fit line drawn for the data more accurate than simply dividing the total distance by the total time?
It isn't.
Why is this??? I said it was more...
Of my 10 questions on this prelab these were the 3 I had difficulty on.
Why will a car accelerate on an incline?
I said because of the cars positioning it will have a better pick-up due to an incline.
Suppose a car is traveling along a perfectly horizontal surface and begins to slow...

Velocity question?? Need help..
An 80.0 kg man is standing on a frictionless ice surface when he throws a 4.00 kg book at 20.0 m/s. WIth what velocity does the man move across the ice?
Would I be using Mass= weight/gravity?
Astronaut weight = 80.0 kg
Astronaut v = ? m/s

I'm not sure what equation is used on this particular problem.
How much time would be requird to stop a 2,000 kg car that is moving at 80.0 km/hr if the braking force is 8,000 N?
I know.....
Mass 2000 kg
Acceleration is 80.0 km/hr
Breaking force is 8,000 N

Need help showing diagrams......
I am to draw diagrams of:
There are 16 units is a cad and 5 units is a gad:
how many gads in a cad? I know 16/5 = 3.2
how many cads in a gad? I know 5/16 or .3125
One cad is what percent of one gad? 16/5 * 100 = 320
ONe gad is what percent of one cad...
