Answer:
doubled as well.
Explanation:
Using what I call "Method of Simplest Integers," insert all charges and distance as just 1 (ignore k, because it is a constant), so
Fe=k(1*1)/(1^2)=k(1)/1=k(1)
Since one of the charges is doubled,
Fe'=k(2*1)/(1^2)'k(2)/1=k(2)
Set Fe and Fe' side by side and compare their outcomes. cancel out k, because it's constant, and find out what multiple makes Fe becomes Fe'. In this case, it is 2. So the force would be doubled if one of the

Answer:
its speed when its height was half that of its starting point is 25.46 m/s
Explanation:
Given;
final speed of the roller coaster, v = 36 m/s
Applying general equation of motion;
V² = U² + 2gh
where;
V is the final speed of the roller coaster
U is the initial speed of the roller coaster = 0
h is the height attained at a given velocity
36² = 0 + (2 x 9.8)h
1296 = 19.6 h
h = 1296/19.6
h = 66.1224 m
when its height was half that of its starting point, h₂ = ¹/₂ h
h₂ = ¹/₂(66.1224 m) = 33.061 m
At h = 33.061 m, V = ?
V² = U² + 2gh
V² = 0 + 2 x 9.8 x 33.061
V² = 648
V = √648
V = 25.46 m/s
Therefore, its speed when its height was half that of its starting point is 25.46 m/s
Velocity is directly proportional to wavelength and frequency.
<h3>How the changes in velocity, frequency and wavelength are related?</h3>
There is direct relationship present between velocity and frequency as well s wavelength. If velocity increases, wavelength and frequency are also increase and vice versa. The higher the speed of a sound, the greater its wavelength for a given frequency.
So we can conclude that Velocity is directly proportional to wavelength and frequency.
