Which of the following can you conclude about a particle labeled 1/0 n? Check all that apply. A. it is an alpha particle B. it has one proton C. it has no neutrons D. it is a beta particle E. it has one nucleon F. it has one neutron G. it has one electron PLEASE HURRY, in the middle of a test as of now :) Thank you kindly

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

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
