Answer:
In the attached link is the answer.
Explanation:
Answer:
speed when it reaches y = 4.00cm is
v = 14.9 g.m/s
Explanation:
given
q₁=q₂ =2.00 ×10⁻⁶
distance along x = 3.00cm= 3×10⁻²
q₃= 4×10⁻⁶C
mass= 10×10 ⁻³g
distance along y = 4×10⁻²m
r₁ =
=
= 3.61cm = 0.036m
r₂ =
=
= 5cm = 0.05m
electric potential V = ![\frac{kq}{r}](https://tex.z-dn.net/?f=%5Cfrac%7Bkq%7D%7Br%7D)
change in potential ΔV = ![V_{1} - V_{2}](https://tex.z-dn.net/?f=V_%7B1%7D%20-%20V_%7B2%7D)
ΔV =
, where
2.00μC
ΔV = ![2kq(\frac{1}{r_{1}} - \frac{1}{r_{2} })](https://tex.z-dn.net/?f=2kq%28%5Cfrac%7B1%7D%7Br_%7B1%7D%7D%20-%20%5Cfrac%7B1%7D%7Br_%7B2%7D%20%7D%29)
ΔV = 2 × 9×10⁹ × 2×10⁻⁶ × ![(\frac{1}{0.036} - \frac{1}{0.05} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B0.036%7D%20-%20%5Cfrac%7B1%7D%7B0.05%7D%20%29)
ΔV= 2.789×10⁵
= ΔV × q₃
ˣ 10×10⁻³ ×v² = 2.789×10⁵× 4 ×10⁻⁶
v² = 223.12 g.m/s
v = 14.9 g.m/s
Answer:
1.35 miles
Explanation:
Since the slope is 14% grade = -14/100. This is a negative slope.
The distance of 1000 ft descended is a vertical descent, so assuming our initial position is 0, and Δx is the change in horizontal distance.
tanθ = -14/100 = (0 - 1000)/Δx = - 1000)/Δx
-14/100 = - 1000)/Δx
Δx = -1000 × -100/14= 7142.86 ft
5280 ft = 1 mile
7142.86 ft = 7142.86/5280 miles = 1.353 miles ≅ 1.35 miles

Explanation:
The cowbird is a natural enemy to the sparrow. It is sort of a disease to the a disease to the sparrow. That being so, when the disease goes away, the sparrow bird population should go up. Fewer deaths due to the cowbird, means more sparrows around.
