lyudmila [28]

Answer:

The equivalent resistance of the combination is 3.42 ohms.  

Explanation:

We have,

8 ohms resistor is connected in parallel with a 6 ohms resistor. It is required to find the equivalent resistance of this combination.

For a parallel combination, the equivalent resistance is given by :

\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}

Plugging the values of R₁ and R₂, we get :

\dfrac{1}{R_{eq}}=\dfrac{1}{8}+\dfrac{1}{6}\\\\R_{eq}=3.42\ \Omega

So, the equivalent resistance of the combination is 3.42 ohms.

3a) w = mg = 60 x 10 = 600N
b) W = fd = 600 x 10 = 6000J
c) chemical to gravitational potential via the mechanical pathway

4a) W = fd = 200 x 0.5 = 100J
b) chemical to kinetic via mechanical pathway

5a) F = W/d = 40000/20 = 2000N
