What statements best define percent error? check all that apply. it is a mathematical way of showing accuracy. the higher the percent error, the more accurate the data set. the higher the percent error, the less accurate the data set. only the experimental value is needed to calculate percent error. only the actual, or accepted, value is needed to calculate percent error. a percent error always has a positive value.

Arescue plane flying horizontally at spots a survivor in the ocean directly below and releases an emergency kit with a parachute. because of the shape of the parachute, it experiences insignificant horizontal air resistance. if the kit descends with a constant vertical acceleration of, how far away from the survivor will it hit the waves?

Your town is considering building a biodiesel power plant describe at least two advantages and two disadvantages

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
