Answer:
Explanation:
1) emf stands for elactro-motive force and represents the ability to move electrical charge carriers. Commonly referred to as Volts.
2) P = VI = 1.5(0.31) = 0.465 ≈ <u>0.47 W</u>
3) P = 0.465 - I²R = 0.465 - 0.31²(0.65) = 0.402535 W = J/s ≈ <u>0.40 J</u>
4) 14000 J / 0.40 J/s = <u>35 000 s </u> or about 9.75 hrs

Answer:
1.28 m, 14 m/s
Explanation:
At the maximum height, the velocity is 0.
Given:
a = -9.8 m/s²
v₀ = 5.00 m/s
v = 0 m/s
x₀ = 0 m
Find:
x
v² = v₀² + 2a(x - x₀)
(0 m/s)² = (5.00 m/s)² + 2(-9.8 m/s²) (x - 0 m)
x = 1.28 m
The maximum speed is at the bottom of the well.
Given:
a = -9.8 m/s²
v₀ = 5.00 m/s
x₀ = 0 m
x = -8.5 m
Find:
v
v² = v₀² + 2a(x - x₀)
v² = (5.00 m/s)² + 2(-9.8 m/s²) (-8.5 m - 0 m)
v = -13.8 m/s
Rounded to 2 sig-figs, the maximum speed is 14 m/s.
