Answer:
They are standing 3 feet away from each other
Explanation:
If Nathan Is standing 2 feet away from the mirror. Then Hiva is standing 7 feet away from the mirror is she is standing 5 feet further than him. They are standing 3 feet away from each other.
Neon is element #10, so every neon atom has 10 protons in the nucleus.
If it also has 9 neutrons in there, then its mass number is (10 + 9) = <em>19</em> .
A)
2revs in 0.08s
so in 1s thats 25revs
therefore thats <u>50π radians</u> in one second
b)
well, ω=2π/T
therefore ω=50π = 157.079rads^-1
and v=rω where r is in meters;
v=0.3x157.079
<u>v=47.123ms^-1</u>
c)
f=1/T
f=1/period for one rotation
1 rotation = 0.08/2 = 0.04
f=1/0.04
<u>f=25Hz</u>
Answer:
absorbed/taken in
