Nine tree lights are connected inparallel across 120-V potential difference. The cord to the wall socket carries a current of 0.

jok3333 [9.3K]

Answer:

a)3000ohm

b)4.44mA

Explanation:

a) we were given a Nine tree lights connected inparallel across 120-V potential difference, since the resistor are in parallel we use the expresion below

1/R(total)= 1/R₁ + 1/R₂ + 1/R₃ + 1/R₃ +.... 1/R₉

But according to ohm'law which can be expressed below

V=IR

R=V/I

R(total)= 120/0.36

= 333.33ohm

1/R(total)= 1/R₁ + 1/R₂ + 1/R₃ + 1/R₃ +.... 1/R₉

R₁=R₂ =R₃ =R₄= R₅=R₆=R₇=R₈=R₉

1/R(total)=9/R

1/333.33= 9/R

R= 3000ohm

Therefore, the resistance is 3000ohm

b)the bulbs were connected in series here, then for series connection we use below expression

R₁=R₂ =R₃ =R₄= R₅=R₆=R₇=R₈=R₉

R(total)=9R

= 9*3000

=27000ohm

I=VR

I=V/R

I= 120/27000

= 4.44*10⁻³A

4.44mA

Therefore, the current is 4.4mA

How long will it take a ball to hit the ground if it's dropped from a height of 2.0 m?

love history [14]

Answer:

0.63 s

Explanation:

We have,

Height, h = 2.0 m
Initial velocity, u = 0 m/s
Acceleration due to gravity, g = 10 m/s²

We have to find the time taken.

⠀⠀⠀⠀⇒ h = ut + ½gt²

⠀⠀⠀⠀⇒ h = ½gt²

⠀⠀⠀⠀⇒ 2 = ½ × 10 × t²

⠀⠀⠀⠀⇒ 2 = 5 × t²

⠀⠀⠀⠀⇒ 2/5 = t²

⠀⠀⠀⠀⇒ √(2/5) = t

⠀⠀⠀⠀⇒ 0.63 s = t

Therefore, time taken is 0.63 seconds.
