Answer:
.15s
Explanation:
Follow the units here. If you divide 300.000m by 2000m/s then you'll end up with the meters reduced and just the seconds. So that's what you do to get the time:
(300.000m)/(2000m/s ) =
(300.000/2000)(m•s/m) =
0.15s

Answer:
4.384 * 10^13
Explanation:
Given the expression :
[(6.67 * 10^-11) * (1.99 * 10^30)] ÷ [(1.74*10^3)*(1.74*10^3)]
Applying the laws of indices
[(6.67 * 1.99) *10^(-11 + 30)] ÷ [(1.74 * 1.74) * 10^3+3]
13.2733 * 10^19 ÷ 3.0276 * 10^6
(13.2733 / 3.0276) * 10^(19 - 6)
4.3840996 * 10^13
= 4.384 * 10^13
THE ANSWER IS 16 ohms or however its spelled
