explain how average speed and average velocity are related to each other for an object in uniform motion
2 answers:
Explanation:
Average speed and average velocity both are different quantities.Speed is a scalar quantity but on the other hand velocity is a vector quantity.Speed deals with distance but on the other hand velocity deals with displacement and we know that displace is a vector quantity that is why velocity is a vector quantity.
If object is in uniform motion then speed and velocity will become same.

Answer:
2.40 x 10⁻¹³ C
Explanation:
= number of electrons = 6.25 x 10⁶
= charge on electron = - 1.6 x 10⁻¹⁹ C
= number of protons = 7.75 x 10⁶
= charge on proton = 1.6 x 10⁻¹⁹ C
Net charge is given as
Q =
+
Q = (- 1.6 x 10⁻¹⁹) (6.25 x 10⁶) + (1.6 x 10⁻¹⁹) (7.75 x 10⁶)
Q = 2.40 x 10⁻¹³ C
