Homework Statement
A spy camera is said to be able to read the numbers on a car’s license plate. If the numbers on the plate are 5.0 cm apart, and the spy satellite is at an altitude of 160 km, what must be the diameter of the camera’s aperture? (Assume light with a wavelength of 550 nm.)...
Homework Statement
Find the volume of the region bounded by the curves y=3x-2, y=6-x, and the x-axis when the region is rotated around the y-axis.
Homework Equations
Volume using cylindrical shells: 2π∫r(x)h(x)dx
The Attempt at a Solution
I graphed the curves and then found the x-intercept...
Hello,
Since it was mentioned in my textbook, I've been trying to find Riemann's proof of the existence of definite integrals (that is, the proof of the theorem stating that all continuous functions are integrable). If anyone knows where to find it or could point me in the right direction, I...
Assuming there is no friction, the force required to cause the mass to move at a constant rate is equal to the component of the mass's weight down the 30-degree incline. When this happens, the total net force on the mass is zero as the accelerative force (gravity) is canceled out, and it moves...
You can think of space and time as two sides of the same coin, which would be spacetime. This is the main idea behind general relativity. Space and time are two separate things, but are united (some prefer "married") by the theory of relativity.
I've dabbled in piano, but I was awful at it, so I looked around for other instruments. I can play decent flute and saxophone, though the baritone kills me because my hands are miniscule. I really appreciate what you said about approaching music from the perspective of a scientist, though; it's...
You've probably heard of them before, but the Feynman lectures are a really great resource. They're a little lengthy, but they're easy to understand, and the math is comprehensible. I also subscribe to Physics Today, which has a monthly section on recent textbooks and physics books, a decent...
Thanks a lot for the information. Do you have any recommendations for introductory computer programming/Linux books or calculus books? For math proficiency, I've taken Algebra I and I'm currently in Geometry.
Just to alert you, your link is broken, but if you have the same answer as the book, you're fine.
You asked why the book used T instead of F. T stands for tension, which is a type of force that seeks to pull something apart; basically, it can be found in strings or pulleys, which I'm guessing...
I'm a freshman taking a geometry class right now, and I couldn't agree with you more! I really enjoy seeing the general theory behind math rather than just crunching numbers all day. Exponents were my nemesis in Algebra I.
I am a freshman in high school, and I would be really interested in doing some sort of physics program over the summer. I'd be especially curious about doing an unpaid internship or taking a class at a college. Would this be at all possible? If so, what programs could you recommend? Thanks in...
