because you have to divide the length by the height of the incline.
Answer:
Explanation:
more the density , more will be the buoyant force acting on it , less the density less will be the buoyant force acting on it. This is why people float in dead sea and sink in other seas
Answer:
Cost = $ 3,995
Explanation:
Let's start by looking for the energy consumed, which is the power over time
E = P t
The power is 65 W, the time is 12 h each day, in a period of 30 days the time is
t = 12 30 = 360 h
E = 65 360
E = 23,500 W h
We reduce to KW h
1 kW = 1000 W
E = 23.5 kW h
Let's use a direct ratio rule (rule of three) to find the cost
Cost = 23.5 17.0
Cost = 399.5 c
Cost = $ 3,995
To answer the problem we would be using this formula which isE = hc/L where E is the energy, h is Planck's constant, c is the speed of light and L is the wavelength
L = hc/E = 4.136×10−15 eV·s (2.998x10^8 m/s)/10^4 eV
= 1.240x10^-10 m
= 1.240x10^-1 nm
