HELP ASAP I HAVE LOTS MORE AND WILL DO BRAINLIEST <3 1. Describe the process you would use to find the magnitude (length) of the rest
two perpendicular vectors, one in the x-direction, and another in the y-direction.

2. Lisa is solving a vector problem, and the answer she arrives at is 17.4 m/s at 11° Why
is this answer, as it is currently written, not complete?

3. When solving projectile problems, you may hear that "motion in the x- and y-directions
are independent of each other." What does this mean, in terms of your problem solving?

If the speed of a particle triples ,by what factor does its kinetic energy increase?

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?

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?
