For some mysterious reason, we can't see the graph.
On a position/time graph, constant velocity is represented by a <em>straight line</em>. Depending on the velocity, the line may be sloping up, sloping down, or horizontal. The only thing the line on the graph <u><em>CAN't</em></u> be is vertical.
Ohm's law states that:
Explanation:
Ohm's law states that in a conductor, the potential difference across the conductor is directly proportional to the current flowing through it. Mathematically,
where
V is the potential difference
I is the current
The constant of proportionality is called resistance (R), and it gives a measure of "how much the conductor opposes" to the flow of current. Therefore Ohm's law can be rewritten as
where R is the resistance. By rewriting the equation as
we see that the larger the resistance, the lower the current in the conductor.

Answer:
52 m/s
Explanation:
Wavelength is the distance between two successive crests. Two crests make one circle hence 16 cycles are equal to 16 wavelengths. Each wavelength is equal to 208/16=13 m long
Speed of wave is given as the product of wavelength and frequency, expressed as
S=fw
Where f is the frequency and w is the wavelength
Substituting 13 m for w and 4 Hz for f then
S=4*13=52 m/s
Therefore, the speed is equivalent to 52 m/s

Bond order for ¹⁴N - ¹⁶O bond:
= (number of bonding electrons - number of antibonding electrons)/2
= [ (2 from N +4 from O) - 1 from N ] / 2 = 2.5
m1 = 14u m2 = 16u
reduced mass = μ = m1 * m2 / (m1 + m2)
= 112/15 = 7.47 u
μ = 7.47 * 0.001 kg / 6.023 * 10²³ = 1.239 * 10⁻²⁶ kg
k = force constant = 1150 N/m
c = speed of light = 3 * 10¹⁰ cm/s</span>
