We have a system of two unequal oppositely charged point charges, of which ##q_2## is smaller and ##d## is the distance between charges. There is an equipotential spherical surface of potential ##V=0## that encloses a charge of lesser absolute value. The task is to find parameters of that...
z_k=\sqrt[n]{u}=\sqrt[n]{r}e^{i\left(\frac{\phi+2k\pi}{n}\right)}, k=0,1,2,...,n-1
and
z_k=\sqrt[n]{u}=\sqrt[n]{re}^\frac{\phi+2k\pi}{n}, k=0,1,2,...,n-1
Which one is incorrect (note that in the first, e is out of the root)?
I am taking about MAME - Multiple Arcade Machine Emulator and MESS, which is based on MAME as its core (MESS stands for "Multi Emulator Super System").
Both are software emulators for video games.
MESS supports many platforms and I am wondering does MAME supports the same platforms, since...
Question 3:
We have a damped harmonic mechanical oscillator - a moving body on the spring.If force of damping is proportional to the speed of that body then:
a)none of the statements below is true - CORRECT
b)frequency decreases with time - INCORRECT,SINCE FREQUENCY IS NOT FUNCTION OF...
Question 2:
The second question is about equation which describes a wave in air which originates from vibrating string attached to both of its ends and strained by some force.I know that people in United States and UK represent this equation in different form,so I`ll describe every...
Question 1.
From kinematics we have a=\frac{\mathrm{d}^2s}{\mathrm{d}t^2} which means,as I understood it:to get the acceleration,we first derive distance with respect to time,then again derive the result of that operation with respect to time.
If so,wouldn`t be more appropriate to write...
