An asteroid is heading towards us at 11 km/s . scientists decide the best solution is to attach a rocket to the asteroid and fire it to change the trajectory of the asteroid. if the rocket is fired for 8 min, the scientists calculate that the new speed for the asteroid will be 20 km/s and its new trajectory will be at an angle of 29 degrees to its original path. in the process described above, what is the acceleration of the asteroid?
express your answers using two significant figures separated by a comma. assume that the positive x axis is in the direction of the initial motion of the asteroid. the final motion of the asteroid has components in the x and positive y directions only.

Which object is most likely represented by a dot?

What will a positive and a negative charge do if they are separated from each other?

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
