You should first break up all the distances and directions into vectors and then add all horizontal vectors and verticle vectors.
He goes, 5 + 1 m east = 6m East
3 m north
displacement = root(6^2 + 3^2) = 6.708m
direction = arcTan(verticle/horizontal) = arcTan(3/6) = 26.565 degrees
Would it be an open cluster
Answer:
<h2>a</h2><h2> move with an increasing velocity</h2>
B. venus. although mercury is closest to the sun, venus is hotter, day & night. heat can escape mercury which is why it gets cold despite being so close to the sun. however venus is hottest because whenever heat gets there it never leaves due to the atmosphere venus has.
we know that,
Frequency = 1/ time period
hence, Feq = 1/5 ===> 0.2 Hz
hence, wave velocity = freq * wavelength
hence,
V = 0.2 * 100
==> Wave velocity = 20 m/s
