Answer:
60 deg from Y-axis is 150 deg from X-axis
x = L cos theta = 23,2 cos 150 = -.867 * 23.2 = -20.1

Answer:
6.98 × 10^(14) Hz
Explanation:
wavelength in air; λ_o = 430nm = 430 × 10^(-9) m
Speed of violet light in the prism; v = 2 × 10^(8) m/s
Speed of light in air = 3 × 10^(8) m/s
To get the frequency, we will use the relationship;
f = c/λ_o
Plugging in the relevant values;
f = (3 × 10^(8))/(430 × 10^(-9))
f = 6.98 × 10^(14) Hz
I think the first big picture is group communication, the second one with the person talking in front of everyone is public communication, and the last one is dyadic communication
Answer:
The coefficient of friction is dimensionless, which means it has no units. It is a scalar, which means that the direction of the force seems to have no effect upon that physical... This coefficient of friction seems to be unitless or we could say a dimensionless ratio of frictional force to normal reaction.
