Average speed =
(distance covered during some period of time)
divided by
(length of time to cover that distance).
A. it is <span>located at a distance of 2.6 million light years from earth</span>
Time t = ?
<span>When wave is moving from
y = 0 to y =12 cm</span>
By using the formula,
y = 15cos [(π/12) t)] =
0,
cos [(π/12) t)] = 0 =
cos (π/2), so,
(π/12)t = π/2,
t = (π/2) (12/π)
t = 12/2
<span>t = 6 sec</span>
<span>so 6 sec is the least amount of time required</span>
Answer:
it probs gos fast then it was it would be easy if u asked us if their was any mass or friton
