Answer:
5
Explanation:
electrons can be more than det
Answer:
If one charged object is positive, and the other charged object is negative, then the two objects will attract each other. If both objects are positive, the objects will repeal each other. If both objects are negative, the objects will also repeal each other.
V - the wind velocity;
53° - 35° = 18°
v² = 55² + 40² - 2 · 55 · 40 · cos 18°
v² = 3025 + 1600 - 2 · 55 · 40 · 0.951
v² = 440.6
v = √440.6
v = 20.99 ≈ 21 m/s
Answer: The wind velocity is 21 m/s.
An expression which can be used to evaluate the relative error in g (in terms of h, Δh, t, and Δt) is: 
<h3>What is
relative error?</h3>
Relative error can be defined as a measure of the ratio of an absolute (real) value of a measurement to an expected (theoretical) value. Also, it's independent of the magnitude of its values.
<h3>How to evaluate the
relative error in
g?</h3>
In order to write this expression, we would divide the absolute (real) value by the expected (theoretical) value as follows:

<u>Note:</u> g = 2h/t²
