The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 3 amperes when the resistance is 810 ohms. What is the current when the resistance is 413 ohms? Round to the

nearest tenth of an ampere if necessary. A)1.5 amperes B)0.65 amperes C)5.9 amperes D)0.17 amperes

  C)  5.9 amperes

Explanation:

When the resistance changes by a factor of 413/810, the inverse proportionality means the current changes by a factor of 810/413.

  (810/413)(3 A) ≈ 5.884 A ≈ 5.9 A

The current is about 5.9 amperes.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
