On level ground a shell is fired with an initial velocity of
at 60.0° above the horizontal and feels no appreciable air
resistance. (a) find the horizontal and vertical components of the
shell’s initial velocity. (b) how long does it take the shell to reach
its highest point? (c) find its maximum height above the ground.
(d) how far from its firing point does the shell land? (e) at its
highest point, find the horizontal and vertical components of its
acceleration and velocity.

Anybody wanna ? (picture included? )

Atank is filled with an ideal gas at 400 k and pressure of 1.00 atm . part a the tank is heated until the pressure of the gas in the tank doubles. what is the temperature of the gas?

You are the coordinator for a program that is going to take place at night in a rectangular amphitheater in the mountains. you will have no access to any electricity, but you must be able to illuminate the entire grounds. you know the intensity of the light from a lantern varies inversely as the square of the distance from the lantern. suppose the intensity is 90 when the distance is 5 m. a. write an equation to model the situation. b. solve for the constant of variation. c. write the equation to model the situation using the constant () of variation. d. you have been given lanterns with 40 light intensity. use your equation to solve for the distance from the lantern. e. you need to illuminate 225 km. how many meters do you need to light? f. how many lanterns will you need?
