Answer:
360,000
Explanation:
This is because the density is per kilogram so you would just multiply 2400 by 150 to give you 360000.

Answer:
515 nm
Explanation:
The equation that gives the position of the maxima (bright fringes) in the interference pattern produced on a distant screen by the diffraction of light through two slits is

where
y is the distance of the maximum (bright fringe) from the central maximum
m is the order of the maximum
is the wavelength of the light used
D is the distance of the screen
d is the separation between the slits
In this problem we have:
is the separation between the slits
D = 3.30 m is the distance of the screen
m = 1 (we are analyzing the 1st bright fringe)
is the distance of the 1st bright fringe from the central maximum
Solving for
, we find the wavelength of the light used:

Using s=1/2 a t ^2
25 = 1/2 x 0.5 x t^2
t = square root (25/0.25)
t = 10 seconds
