Answer:
Step-by-step explanation:
The equation for photon energy is given by:
Where:
This equation telling us that the higher the frequency of the photon, the greater its energy. And the longer the photon wavelength, the lower its energy.
So, replacing the data provided in the previous equation:
Answer:
Sample Space = {A, B, C, D, E, F}.
Sample space for choosing C to F = {C, D, E, F}.
Step-by-step explanation:
All six letters are included in the first set of possible outcomes.
Four letters (C to F) are included in the second set of possible outcomes.
For this unit conversion problem, you'll need to know:
1 m = 100 cm
Now let's convert with this conversion ratio!
Answer:
1 hour
Step-by-step explanation:
I find these easiest to work by considering the initial difference in distance and the speed at with that gap is closing.
__
The gap is 15 miles, the distance the first ship is from harbor when the second ship starts.
The rate of closure is the difference in the speeds of the two ships:
60 mph -45 mph = 15 mph
Then the closure time is ...
time = distance/speed
time = (15 mi)/(15 mi/h) = 1 h
It will take the second ship 1 hour to catch up to the first ship.
Remember that an exponent means repeated multiplication.
The exponent of 4 means you have four 
's mutiplied together:
And then each exponent of 2 inside means you have two 
's multiplied inside each set of parentheses.:
There are 8 b's there when you expand this out.
