The motion of an insect wing is quite well modelled as simple harmonic motion. what is true about the acceleration of the wing? (there may be more than one correct choice)a) the magnitude of acceleration is a maximum when the displacement of the wing is zero. b) the magnitude of acceleration is a maximum when the displacement of the wing is a maximum. c) the magnitude of acceleration is zero when the speed of the wing is a maximum. d) the magnitude of acceleration is a maximum when the wing is instantaneously at rest. e) the magnitude of acceleration is a maximum when the speed of the wing is a maximum.

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
