Their frequency stays the same and their wavelength decreases
Answer:
FH ~ 10.02
Step-by-step explanation:
1. Approach
One should first find the circumference of the given circle. Then one should find how large the fraction of the circumference one is supposed to find is. Finally, one should multiply the fraction of the circumference one is supposed to find by the total circumference.
2. Circumference of the circle
The formula for circumference is;
π
Substitute in the given values;
It is given that the radius is, hence
2 (7) π
14π
3. Find the fraction of the circumference one is supposed to find
It is given that the angles over the measure of the total degrees of angles in a circle are equal to the arc surrounding the angles of the circumference. Essentially;

Substitute in the given information and solve;

arc = 
arc = 
arc ~ 10.02
Answer:
-10<0
Step-by-step explanation:
FUTURE VALUE = PRESENT VALUE * (1 + r)^t
PV = 220,000
r = 3%
t = 7 years
FV = 220,000 * (1 + 3%)^7
FV = 220,000 * (1.03)^7
FV = 220,000 * 1.22987386542487
FV = 270,572.25
Answer:
The temperature in Kelvin corresponding to F degrees Fahrenheit is 
Step-by-step explanation:
Given : One can convert temperature from Kelvin into Fahrenheit using the formula
.
To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?
Solution :
Temperature from Kelvin into Fahrenheit is given by,

Writing Kelvin in terms of Fahrenheit,
Subtract 32 both side,

Divide by 95 both side,

Add 273 both side,

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is
