Answer:

  3×10^-12 C  

Explanation:

The total of the three charges is ...

   (-3 +8 +4)×10^-12 C = 9×10^-12 C

Assuming the charge is equally distributed between the balls when they are brought in contact, the charge on each ball will be ...

  (9/3)×10^-12 C = 3×10^-12 C

The heating element of an iron operates at 110 V with a current of 9A. (a) What is the resistance of the iron?
Dmitrij [34]

Answer:

(A) 12.222 ohm (B) 990 W

Explanation:

We have given the voltage of the heating element V = 110 V

The current in the heating element i = 9 A

(a) According to ohm's law V =iR

So 110=9\times R

R=\frac{110}{9}=12.222ohm

(b) The power dissipated in the resistor is given by P=i^2R=9^2\times 12.222=990W

So the power dissipated = 990 W

A very light ideal spring having a spring constant (force constant) of 8.2 N/cm is used to lift a 2.2-kg tool with an upward acc
vampirchik [111]

Answer:

x = 3.5 cm

Explanation:

When spring is used as a lift tool

so the mass suspended on it will have spring force on it

So as per the force equation of mass we can say

F_{net} = ma

now net force on the mass is

F_{net} = kx - mg

F_{net} = kx - mg = ma

here we have

kx = mg + ma

now we have

x = \frac{mg + ma}{k}

x = \frac{2.2(9.8) + 2.2(3.25)}{8.2}

x = 3.5 cm
