Monochromatic light of wavelength 574 nm is incident on a narrow slit. on a screen 2.38 m away, the distance between the second diffraction minimum and the central maximum is 1.82 cm. (a) calculate the angle of diffraction θ of the second minimum. (b) find the width of the slit.

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.

Heterogeneous mixture with larger particles that never settle is

Asmall 12.00g plastic ball is suspended by a string in a uniform, horizontal electric field with a magnitude of 10^3 n/c. if the ball is in equilibrium when the string makes a 30 ° angle with the vertical, what is the net charge on the ball?
