Answer:
8/15=0.53..., since the 3 is repeating, just stop at the 4th decimal place, thus
0.5333
Explanation:
It falls down and I hate that this makes me type a lot
Answer:
30.81°
Explanation:
θ₁ = angle of incidence = 50°
θ₂ = Angle of refraction
n₂ = Refractive index of glass = 1.5
n₁ = Refractive index of air = 1.0003
From Snell's Law
Using Snell's law as:


Angle of refraction= sin⁻¹ 0.5122 = 30.81°.
-12 = 6.2*t - 4.9*t² → t = 2.32 sec (quadratic formula)
<span>V = Vi -g*t = 6.2 - 9.8*2.32 = -16.5 m/s</span>
difference across the 12.0 Ω resistor is 1.20 V, calculate the emf of the cell. 45. Req = 13.5 Ω ... (b) I = V / Reff = 1.5 / 2 = 0.75 A.
