Asatellite is in a circular earth orbit of radius r. the area a enclosed by the orbit depends on r2 because a = πr2. determine how the following properties of the satellite depend on r. in each case, give the power of r, i. e., if the dependence goes as rn, give n. if there is no dependence, then n = 0. (a) period, (b) kinetic energy, (c) angular momentum, and (d) speed.

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

What object a collides with object b and bounces back its final momentum is?

The atoms in a nickel crystal vibrate as harmonic oscillators with an angular frequency of 2.3 × 1013 rad/s. the mass of a nickel atom is 9.75 × 10-26 kg. what is the difference in energy between adjacent vibrational energy levels of nickel? (h = 6.626 × 10-34 j • s, , 1 ev = 1.60 × 10-19 j)
