ASAP!! please answer as much as you can it would be so appreciated! 2. A projectile is fired with a velocity of 196 m/s at an angle of 60.0° with the horizontal. Calculate:
(98.0m/s,170 m/s, 34.6 s, 3391 m, 1473 m)
(a) the vertical velocity and the horizontal velocity of the projectile
(b) the time the projectile is in the air
(c) the horizontal distance the projectile travels
(d) the maximum height the projectile reaches

The metric unit of electrical power is the watt volt ampere ohm

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
