Hydrogen and then its helium
<em>Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.</em>
Answer:
The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.

Answer:
2.316e-3 and 3.47e-3
Explanation:
Now, at that angle, we look at the bright spots on the screen.
tan θ = x / L (x is the horizontal distance from the centre of the screen, L is distance to screen)
For small angles, we can approximate that tan θ = sin θ.
nλ / d = x / L so then
x = n λ L / d
First bright fringe, n = 1
x = (1) (641*10^-9 m) (3.65 m) / (1.01*10^-3 m) = 2.316e-3
For destructive interference (dark fringes), equation becomes:
x = (n - 0.5) λ L / d
Second dark fringe, n = 1.5
x = 1.5 (641*10^-9 m) (3.65 m) / (1.01*10^-3 m) = 3.47e-3
