Light of wavelength 619 nm passes through a double slit, and makes its first maximum (m=1) at an angle of 0.226 deg. what is the separation of the slits, d, IN MILLIMETERS?

(remember milli means 10^-3.)
(unit=mm)

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced?

The direction of the current in an alternating current circuit remains constant. is direct. changes repeatedly. changes randomly.

Aparticle initially located at the origin has an acceleration of = 2.00ĵ m/s2 and an initial velocity of i = 8.00î m/s. find (a) the vector position of the particle at any time t (where t is measured in seconds), (b) the velocity of the particle at any time t, (c) the position of the particle at t = 7.00 s, and (d) the speed of the particle at t = 7.00
