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
The power consumed by the electric clothes dryer may be calculated by the following equation,
P = I x V
where P is the power, I is the current in amperes, and V is the voltage in volts. Substituting the known values from the given above,
P = (15 A)(240 V)
P = 3600 watts
Therefore, the power consumed by the electric clothes dryer is equal to 3600 watts.
Unbalanced force.
The definition of an unbalanced force is a force that changes the position, speed or direction of the object to which it is applied.
When an object is still it means that is is balanced force. So you would need to add more force to another side to make it move. Which is unbalanced force.
Answer: you get static electricity. U can shock others easily with this thing u could play pranks but i suggest not to ;-;
