The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly. ... From left to right, they are Mercury, Venus, Earth, and Mars.
Explanation:
<span>Rutherford felt that the atom had an internal structure much like our solar system, with a nucleus surrounded by orbiting electrons. Today, we know that the electrons inhabit specific shells and sub-shells, and there is an order to which these electrons are located.</span>
Answer: concentration c = 25.2 g /(41.99 g/mol × 0.75 l)
Explanation: M(NaF) = 41.99 g/mol and amount of substance n = m/M.
Concentration c = n/V
Answer:
-29.4 m/s
Explanation:
Initial velocity is 0 m/s.
Acceleration is -9.8 m/s².
Time is 3.0 s.
v = at + v₀
v = (-9.8)(3.0) + 0
v = -29.4 m/s
