Force = mass*acceleration so
3.6*2.5 =9 Newtons
Orbital periods of stars in the Galaxy
Answer:
= 1.6
Explanation:
= Angle of incidence = 65.9°
= Angle of refraction = 34.8°
= Index of refraction of air = 1
= Index of refraction of glass = ?
Using Snell's law
Sin =
(1) Sin65.9 = Sin34.8
= 1.6
A watt is the SI derived-unit for one joule per second, so the correct answer is C. A watt corresponds to the power in an electric circuit in which the potential difference is one volt and the current is one ampere.
