Answer:
11.87 ms⁻¹
Explanation:
You can use the kinematic equation
v² = u² + 2as
Where v = final velocity
u = initial velocity
a = acceleration
s = displacement
v² = 9² + 2×1.5×20
So you get v = 11.87 ms⁻¹
I believe the answer you are looking for is perception.
Answer:
negative, positive
Explanation:
A we know that the electrons have a negative charge.
So, when a body has some excess electrons, it means it has negative charge.
When a body has an deficiency of eletrons, it means it gains a positive charge.
An area with excess electrons has a net _<u>negative</u>__ charge; an area with a deficit of electrons has a net _<u>Positive</u>____ charge.
