The quantities v, k, u, and l all represent physical quantities characterizing the orbit that depend on radius r. indicate the exponent (power) of the radial dependence of the absolute value of each. express your answer as a comma-separated list of exponents corresponding to v, k, u, and l, in that order. for example, -1,-1/2,-0.5,-3/2 would mean v∝r−1, k∝r−1/2, and so forth.

Answer it orbits high above earth to gain clearer images of light, it magnifies images relative to the human eye, it records most of the universe as it was in the past, not as it is now;

Answer(b) both involve the use of levers;

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
