(10p) What slit spacing is required to give a separation of 4 cm between the second and third order maxima for two slits if a = 366 nm and D = 3.50 m?
(20p) A resistor R, inductor L, and capacitor Care all connected in parallel to an AC source
of EFM. What is the maximum current delivered by the source? (Represent the current
with a phase diagram).

Which of the following are properties of mechanical waves? check all that apply ⭕️ particles of the medium move back and fourth, but do not move with the wave. ⭕️ the particles of the medium always move parallel to the wave motion. ⭕️ wave motion begins with a disturbance in the medium. ⭕️ waves transport energy from a source outward, away from the source.

Work out sian speed for the first 30 minutes of her journey. give your answer in km/h.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
