Biot-Savart law (J.B. Biot, F. Savart)
A law defines the contributions to a magnetic field through an electric current. This is analogous to Coulomb's law. Mathematically specking, it is dB = (mu0 I)/(4 pi r2) dl cross e where dl refer to the infinitesimal directed length of the electric current causing by the magnetic field, I refer to the current passing through that directed length, r refer to the distance from that directed length, & e refer to the unit vector directed from the test point to current-generating length.
Q. Will a DC motor really produce voltage if it is spun in reverse? Answer:- It will produce voltage if you spin it forwards too. The merely difference between a DC motor
Bell's inequality (J.S. Bell; 1964) A quantum mechanical theorem shows that if quantum mechanics were to rely on hidden variables, it ought to have nonlocal properties.

VARIABLE OR NON-UNIFORM VELOCITY: If a body covers unequal displacement in most equal intervals of time, though the smallest interval may be, then the velocity of the body is s
so we just started physics in grade 10, and i dont understand to much of it.. could you help me better understand it? and help me understand what i should expect?
