Answer:

q=13

Step-by-step explanation:

Solve : -q+13 = 0

Subtract 13 from both sides of the equation :

-q = -13

Multiply both sides of the equation by (-1) : q = 13

Answer:

Use the inverse operation to isolate the variable. Undo the subtraction of 4 by adding 4 to both sides of the equation. –4 + 4 = 0, and 9 + 4 is 13. The solution is q = 13. Check the solution by substituting 13 for q in the original equation, and then simplify. 13 – 4 is 9 and 9 = 9 is a true statement, so 13 is the solution.

I do not agree. This is because when the dog was a puppy, she was 370 grams not kilograms. Diego's mistake was mistaking grams for kilograms.

Answer:

A. They have different wavelengths.

B. They have different frequencies.

C. They propagate at different speeds through a vacuum depending on their frequency.

Step-by-step explanation:

Electromagnetic waves have electric and magnetic fields which travel in the free space together. They travel at the speed of light and accelerate by particle oscillates. EM radiations are differently used for different purposes. They are modified in order to create micro waves or radio waves.
