Three resistors, 21 Ω, 58 Ω, and 64 Ω, are connected in series, and a 0.50-A current passes through them. What are (a) the equiv
adoni [48]
<h2>a) Equivalent resistance is 143 Ω</h2><h2>b) Potential difference is 71.5 V</h2>

Explanation:

When resistors are connected in series, effective resistance is given by

                R_{eff}=R_1+R_2+R_3+......

Here

         R₁ = 21Ω

         R₂ = 58Ω

         R₃ = 64Ω

a)      R_{eff}=R_1+R_2+R_3\\\\R_{eff}=21+58+64\\\\R_{eff}=143\Omega

  Equivalent resistance is 143 Ω

b) We know

               Potential difference = Current x Resistance

               V = IR

               I = 0.5 A

               R = 143Ω

Substituting

               V = 0.5 x 143 = 71.5 V

Potential difference is 71.5 V

What is the primary force help suspension bridges use cables to hold there spans up
snow_tiger [21]

Explanation:

Suspension bridges, like the Golden Gate Bridge or the Brooklyn Bridge, use tension force as the primary source of force that cables use to hold their spans up. The supporting cables receive the tension forces of the bridge, and this same force passes to the anchorages and into the ground

Why we cannt cook food on high attitude (like mountain where exist low temperatures )? ​
zloy xaker [14]
Cooking takes longer because water and other liquids evaporate faster and boil at lower temperatures.At sea level water boils at 212degrees Fahrenheit but at an altitude of 7,500 feet, it boils at about 198 degrees. Foods that are prepared by boiling or simmering will cook at a lower temperature and it will take longer to cook them. Hope this helps!! ; )
