Hi, thank you for posting your question here at Brainly.
To find the velocity of light or any electromagnetic wave, we use the equation: v = wavelength * frequency. Substituting,
v = 0.5 m * 930 1/s
v = 465 m/s
It's 15 because
3 groups and 5 people in each group
and becomes 15
I HOPE THIS HELPS
Answer:
3 hours
Step-by-step explanation:
290.28-200.22=90.06
90.06/30.02=3
B: 7 x 6 = 42 and the only reason that B is the answer is because a quotient is the word used for a answer when you multiply c:
6(n+1)= ?? When n = 9
6(9+1)=?
6x10=60
