If an object of 0.550 kg is lifted from the floor to a height of 3.50m, how much work is done by the lifting force, what is the kinetic energy, and what is the velocity?

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20

In an experiment, how can i change human errors? be specific.

Afrequency generator sends a 550 hz sound wave through both water and ice. what is the difference in wavelength between the wave produced in ice and the wave produced in water?
