Move your cannon back to ground height, and set the initial speed back to 18 m/s and the launch angle to 65o. Place the target so that it is at a horizontal distance of 19 m from the cannon and a vertical distance of 8 m above the x-axis. Without actually firing the cannon, determine whether or not the projectile will clear the target (that is, go above it) or whether it will fall short (that is, wind up below it). Show all your work below. Once you've got a guess, fire it and see if you were correct.

Select all the correct answers. which changes will increase the rate of reaction during combustion? decreasing the area of contact between the reactants adding more oxygen to the reaction removing heat from the reaction changing the reactants from solid form to powdered form lowering the exposure of the reactants to air

Which of the following list the divisions of the geologic time scale in order from longest to shortest

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?
