Answer:
its good no need to change anything :))
F = focal lenght = 67.1 cm
u= distance between mirror and object = 16.76 cm
1/f = 1/v + 1/u
1/67.1 = -1/16.76 + 1/u
1/67.1 + 1/16.76 = 1/u
u = 13.41
Answer:
4.5 m/s
Explanation:
so, you just divide the displacement or distance (202.5) by the time given (45)
202.5 ÷ 45 =4.5
If a negative object is used to charge a neutral object, then both objects become charged negatively. ... In this case, electrons are transferred from the neutral object to the positively charged rod and the sphere becomes charged positively.
