An object of mass 0.50 kg is released from the top of a building of height 4 m. the object experiences a horizontal constant force of 1.4 n due to the wind blowing. (a) find the time (in s) it takes for the object to strike the ground. s (b) what is the magnitude of the acceleration of the object (in m/s2)? m/s2 (c) through what horizontal distance does the object move (in m) before it hits the ground? m

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 β 103 s. given that the charge of an electron is 1.6022 β 10β19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
