Question

Two satellites have their masses in the ratio 3:1. The radii of their circular orbits are in the ratio 1:4. What is the total mechanical energy of A and B?

Answer 1

Explanation:

each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number,

Answer 2

$\huge \bf E = \frac{GMm}{2r} \\ \huge \bf \frac{E_A}{E_A} = \frac{m_A}{m_B} \times \frac{r_B} {r_A} \\ \huge \bf\frac{3}{1} \times \frac{4}{1} = 12:1$
