What is the equivalent resistance for a parallel circuit that has two resistors: 18.0 ohms and 23.5 ohms?
vovangra [49]

With only two resistors in parallel, it's relatively easy
to calculate their combined equivalent resistance.

                       R  =  (their product) / (their sum)

                           =  (18Ω x 23.5Ω) / (18Ω + 23.5Ω)

                           =           (423Ω²)  /  (41.5Ω)

                           =    10.2 Ω

Murljashka [212]

Answer:

formula

ΔP= PgΔh

Explanation:

Calculation.

ΔP = (1.05 x 10^3kg/m^3)(9.8m/s^2)(6ft equivalent to 1.8288m)

ΔP = 1.05 x 10^3 kg/m^3 x 9.8m/s^2.

x1.8288.

ΔP = 1.88 x 10^4 Pa.

A bike rider was moving to the right at a constant speed. Suddenly the wind then starts blowing against her with 3 N of force to
stiks02 [169]

Answer:

The correct option is D

Explanation:

This question can be better understood when discussed using the Newton's first law of motion which states that an object would continue to move with a uniform speed (in a straight line) unless acted upon by an external force. What happens here (in the question) is that the bike rider would have continued moving at a constant speed (to the right) if not for the opposing force of the wind that acted against her (to the left). <u>This wind/force would cause her speed to reduce or slow down (as posited by the law)</u>.
