The HR diagram is based on brightness and temperature. If you want, you can search up the diagram. Most people classify the sides as Good For You and Bad for you, the bottom would be taste great and taste awful, but the answer is most likely brightness and temperature. Hope this helps you. :)
acceleration (a) = change in velocity / change in time
Δv = final velocity - initial velocity = 4 km/h - 42 km/h = -38 km/h
Δt = 4.75 s
convert km/h to m/s
-38/ 3.6 = -10.56 m/s
a = -10.56 m/s / 4.75 s = -2.23 m/s^2
Answer:
The question continues ; Two of the particles have a negative charge: q1 = -6.3nC and q2 = -12.6nC . The remaining particle has a positive charge, q3 = 8.0nC . What is the net electric force acting on particle 3 due to particle 1 and particle 2?
