A cell has an emf of 1.5 V and an internal resistance of 0.65 Q.
marin [14]

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

Albert dressed as TWO-FACE flips a coin up in the air at an upward velocity of 5.00 m/s. He fails to catch it on the way down an
Colt1911 [192]

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.
