Please guys please i beg you Three charges lie along the ×−axis. One charge, q1 = −12 μC is at the origin. Another charge, q2 = 24 μC is at × = 1.0 m. A third charge, q3 = −36 μC, is placed so that q2 is in electrostatic equilibrium with q1 and q3. How large must the electrostatic force between q2 and q3 be to balance the force of q1 and q2?

Animals respond in various ways to stimuli detected through their senses. some of these responses are stimulated by the presence of danger. which of these animal responses is the best example of a response to an immediate threat? a) a rooster crows every morning at the first sign of light. b) as something approaches an octopus, it shoots a cloud of ink. c) from late fall until spring, bears hibernate to preserve energy. reactivate d) a dog is getting hot in the sunlight, so he moves to a shaded area.

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?
