Answer:
<h2>2.10 meters per second</h2><h2 />
Explanation:
speed (velocity) = distance / time
= <u>0.2 km (1000 m/km) </u>
95 secs.
= 2.10 meters per second
yes ,each piece will remain a magnet because the small pieces will cut into north and south
E=Eq,
where F is the electrostatic force (or Coulomb force) exerted on a positive test charge q.
The correct answer among the choices above is option C. <span>Beryllium, Be, and chlorine, Cl, form a binary ionic compound with a one-to-two ratio of beryllium ions to chloride ions.</span> The chemical formula for the compound of beryllium and chlorine is BeCl2.
Answer:
40 m/s due north
Explanation:
Consider that the south direction a negative Y axis and north direction as + Y axis
v1 = 20 m/s South = 20 (-j) m/s
v2 = 20 m/s North = 20 j m/s
Change in velocity = v2 - v1 = 20 j - 20 (-j) = 40 j m/s
So, change in velocity is 40 m/s due north.
