So this is the quaiton that i have problem w/:
A 4kg bundle starts up a 30 degree incline with 128J of kinetic energy. How far willl it slide up the incline if the coefficient of kinetic friction between bundle and incline is 0.3?
Because E_initial + Work = E_final and the Work done in the...
I am stuck in this gas problem:
You are given a 10.00 gram solid mixture of Ca(ClO_3)_2 and Ca(ClO)_2. When this mixture is heated, both componds decomplse, releasing oxygen gas and leaving behind solid CaCl_2
When this 10.00gram mixture is sealed in a 10.0-Liter evacuated vessel and heated...
I am new to Chem, and I don't quite understand how to solve this problem:
Component of citrus fruits is the bitter compound limonin, which contains only carbon, hydrogen, and oxygen. When a 1.000-gram sample of limonin is subjected to complete combustion, 2.432 grams of CO_2 and 0.574 grams...
Given a wavelength length \alpha, what is the maximum Width (D) of a single slit, which would have no diffraction minima?
It seems like a proof problem to me and I am trying to get a head start.
should I use D * sin (\theta) = m \alpha ?
I find the angle to be 14.48 degree, but I didn't use the 2 meters that the question provdied. Am I missing something?
I use d sin (\theta) = (m + \frac {1}{2} )(0.025m) where d = 0.05m, and m = 0 to find \theta.
This question is related to the wave nature of light from Giancoli:
Water waves having parallel crests 2.5cm apart pass through two openings 5cm apart in a board. At a point 2.0m beyond the board, at what angle relative to the "straight-through" direction would there be little or no wave...
Ok, this problem shows up on my test today and I was wondering how you can solve it:
A circular coil of wire has a diameter of 20 cm and contains 10 loops, internal resistance of 8 ohms, and the coil is placed in a 2.00T external magnetic field. When 1 volt is applied to the coil, determine...
