While standing on a bridge 40.0 m above the ground, you drop a stone from rest. when the stone has fallen 3.80 m, you throw a se

Norma-Jean [14]

Given: distance 1 d₁ = 40 m; distance 2 d₂ = 3.8 m g = -9.8 m/s²

Initial Velocity Vi = 0 Final Velocity of stone 2 is unknown = ?

Total distance dₓ = d₁ - d₂ = 40 m - 3.8 m = 36.2 m

Formula: a = Vf² - Vi²/2d derive for Final Velocity Vf

acceleration is now due to gravity, therefore a = g

Vf = √2gd Vf = √2(9.8 m/s²)(36.2 m)

Vf = 26.64 m/s

Reason: The second stone will still start from rest.

A wire of resistance R is cut into ten equal parts which are then connected in parallel. The equivalent resistance of the combin

Greeley [361]

Answer:

<em>The equivalent resistance of the combination is R/100</em>

Explanation:

<u>Electric Resistance</u>

The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.

Parallel connection of resistances: If R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:

$\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}$
