what is your power output while pushing a 10.0-kg block of steel across a steel table at a steady speed of 2.00 m/s for 3.00 s? you push the block with a force of 60.0 n.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

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

Consider a hydrogen atom in the ground state. what is the energy of its electron? =e= jj now consider an excited‑state hydrogen atom. what is the energy of the electron in the =5n=5 level? =e5= j
