If the charge on the negative plate of the capacitor is 121 nano-Coulomb, how many excess electrons are on that plate? Write you
Julli [10]

Answer:

n = 756.25 giga electrons

Explanation:

It is given that,

If the charge on the negative plate of the capacitor, Q=121\ nC=121\times 10^{-9}\ C

Let n is the number of excess electrons are on that plate. Using the quantization of charges, the total charge on the negative plate is given by :

Q=ne

e is the charge on electron

n=\dfrac{Q}{e}

n=\dfrac{121\times 10^{-9}}{1.6\times 10^{-19}}

n=7.5625\times 10^{11}

or

n = 756.25 giga electrons

So, there are 756.25 giga electrons are on the plate. Hence, this is the required solution.

The free length of the spring that is attached to the 0.3-lb slider is 3 in. If the slider is released from rest when x = 6 in.,
hichkok12 [17]

Answer:

a = 64 ft / s²

Explanation:

The force in a spring is given by Hooke's law

          F = -k x

Let's use the initial data to calculate the spring constant

         k = F / x

Reduscate to the English system

          x = 3 in (1foot/12 in) =0.25 foot

         k = 0.3 / 0.25

         k = 1.2  lb / foot

Now we can use Newton's second law

        F = ma

        a = F / m

        a = -k x / m

        m = w / g

        m = 0.3 / 32 = 0.009375

         x= 6 in (1foot /12 in)= 0.5 foot

        a = - 1.2  0.5  / 0.009375

        a = 64 ft / s²
