Answer:
Explanation:
a) ωp = 2π radians / 1.7 s = <u>3.7 rad/s</u>
b) ωs = 3.7 rad/s(9.5 cm / 4.5 cm) = 7.8 rad/s
v = (ωs)R = 7.8(65) = 507 cm/s or <u>5.1 m/s</u>
c) ωs = 3.5 m/s / 0.65 m = 5.38 rad/s
ωp = 5.38(4.5 cm / 9.5 cm) = 2.55 rad/s
t = θ/ω = 2π / 2.55 = 2.463... <u>2.5 s</u>
Answer: A BaBr2
Explanation:
On the left side of the equation, the superscript 2 is applied to both sodium AND bromine. That means you need 2 bromine on the right. Also on the left side, the 2 AFTER chlorine only applies to the chlorine so there’s only one barium. What you have on the left has to balance with what you have on the right.
