Answer:
6.97 E 16
Explanation:
Frequency is a function of velocity of light to it's wavelength.
Mathematically written as
F = Velocity / wavelength
Velocity of light = 3 x 10^8
Wavelength =430 nm =430 x 10^-9 m
converting wavelength from nanaometer to meter we divide by 10^9
Frequency = (3 x 10^8)/(430 x10^-9) =6.97 E 16
Answer:
The solution set of a disjunction is the union of the solution sets of the individual inequalities. A convenient way to graph a disjunction is to graph each individual inequality above the number line, then move them both onto the actual number line
Explanation:
Answer:
C) 100N
Explanation:
Formula for calculating the Weight of an object is expressed as;
Weight = mass × acceleration due to gravity
Given
Mass of the object = 10kg
Acceleration due to gravity = 9.81m/s²
Substitute into the formula above
Weight = 10×9.81
Weight = 98.1N
Hence the approximate weight of the object is 100N
