I think speed is the answer
To solve this exercise it is necessary to use the concepts related to Difference in Phase.
The Difference in phase is given by
![\Phi = \frac{2\pi \delta}{\lambda}](https://tex.z-dn.net/?f=%5CPhi%20%3D%20%5Cfrac%7B2%5Cpi%20%5Cdelta%7D%7B%5Clambda%7D)
Where
Horizontal distance between two points
Wavelength
From our values we have,
![\lambda = 500nm = 5*10^{-6}m](https://tex.z-dn.net/?f=%5Clambda%20%3D%20500nm%20%3D%205%2A10%5E%7B-6%7Dm)
![\theta = 1\°](https://tex.z-dn.net/?f=%5Ctheta%20%3D%201%5C%C2%B0)
The horizontal distance between this two points would be given for
![\delta = dsin\theta](https://tex.z-dn.net/?f=%5Cdelta%20%3D%20dsin%5Ctheta)
Therefore using the equation we have
![\Phi = \frac{2\pi \delta}{\lambda}](https://tex.z-dn.net/?f=%5CPhi%20%3D%20%5Cfrac%7B2%5Cpi%20%5Cdelta%7D%7B%5Clambda%7D)
![\Phi = \frac{2\pi(dsin\theta)}{\lambda}](https://tex.z-dn.net/?f=%5CPhi%20%3D%20%5Cfrac%7B2%5Cpi%28dsin%5Ctheta%29%7D%7B%5Clambda%7D)
![\Phi = \frac{2\pi(5*!0^{-6}sin(1))}{500*10^{-9}}](https://tex.z-dn.net/?f=%5CPhi%20%3D%20%5Cfrac%7B2%5Cpi%285%2A%210%5E%7B-6%7Dsin%281%29%29%7D%7B500%2A10%5E%7B-9%7D%7D)
![\Phi= 1.096 rad \approx = 1.1 rad](https://tex.z-dn.net/?f=%5CPhi%3D%201.096%20rad%20%5Capprox%20%3D%201.1%20rad)
Therefore the correct answer is C.
KE=1/2mv^2 - equation for kinetic energy
KE=(1/2)(0.12 kg)((7.8 m/s)^2 - plug it into the formula
KE=(0.06 kg)(60.84 m/s) - multiply 1/2 to the mass and square the speed
KE= 3.7 J - answer
Hope this helps
Answer:
1. A <em>series circuit </em>is a closed circuit which has all loads connected in a row and there is only one path for the current to flow.
2. The <em>Ohm's Law </em>state that a current flow through a resistor is directly proportional to the voltage across it ![R = \frac{V}{I}](https://tex.z-dn.net/?f=R%20%3D%20%5Cfrac%7BV%7D%7BI%7D)
3. A <em>parallel circuit </em>is a closed circuit divided into branches that it has two o more paths for the current to flow and the loads are parallel to each other which mean the voltage across them is the same for all loads.
Answer:
3,00,000
Explanation:
because 1 m =100m so, 3000x100=300000
