On connecting a 9V  battery to a Capacitor consisting of two circular plates of radius 0.066 m separated by an air gap of 2. 0 mm. The charge on the positive plate is 544.7 ×10⁻¹² C.

Capacitance of the capacitor is determined by the area of the plate of Capacitor and distance between the plates of capacitor.

Let the area of the Capacitor be A , radius of circular plates be r and distance between the plates of capacitor be d.

Given, Voltage, V = 9V

           Radius, r = 0.066m

           Distance, d = 2mm = 0.002m

Area of the Capacitor, A = πr²

                                     A = π(0.066)²

                                     A = 0.013m²

Capacitance, C = ε₀A / d

                      C = 8.85×10⁻¹²×0.013/0.002

                       C = 60.5 ×10⁻¹² F

                        C = 60.5 pF

We know that Q = CV where Q is the charge on capacitor.

Q = 60.5 ×10⁻¹² × 9

Q= 544.7 ×10⁻¹² C

Since, both plates of a capacitor acquire equal and opposite charge.

Hence the charge on the positive plate of the capacitor is 544.7 ×10⁻¹² C.

What would happen if the difference between the earth and moon decreased?
Natali5045456 [20]
Now, moving the Moon closer to the Earth will increase the gravitational exertion of the satellite onto our planet. If the satellite were slightly closer, the tidal bulge would grow. Low tideswould be lower and high tideswould be higher and any low lying coastline would be flooded.

A 64.0-kg skier starts from rest at the top of a ski slope of height 62.0 m.
Nesterboy [21]

Answer:

Part a)

v = 29.5 m/s

Part b)

v_f = 16.5 m/s

Part c)

F = 2915 N

Explanation:

Part a)

As per work energy theorem we can say that work done by all forces on the ski must be equal to change in kinetic energy

so we will have

W_g + W_{friction} = \frac{1}{2}m(v_f^2 - v_i^2)

now we will have

mgH - 1.10 \times 10^4 = \frac{1}{2}(64)(v^2 - 0)

64(9.80)(62) - 1.10 \times 10^4 = 32 v^2

v = 29.5 m/s

Part b)

Now when the ski mover through a rough path then again we can use work energy theorem to find the final speed after crossing the patch

W_f + W_{air} = \frac{1}{2}m(v_f^2 - v_i^2)

-F_{air} d - \mu mg d = \frac{1}{2}m(v_f^2 - v_i^2)

-(160)(70) - 0.18(64\times 9.8)(70) = \frac{1}{2}(64)(v_f^2 - 29.5^2)

-19102.72 = 32(v_f^2 - 29.5^2)

v_f = 16.5 m/s

Part c)

As the ski strike with snow drift then after moving a distance of d = 3.0 m the ski will stop

so here we can say that work done while it penetrate is equal to change in kinetic energy

-F. d = \frac{1}{2}m(v_f^2 - v_i^2)

- F. 3 = \frac{1}{2}(64)(0 - 16.5^2)

F = 2915 N

Interest groups representing businesses and investors are often among the most successful lobbying groups in foreign policy. Why
alisha [4.7K]

The members of these groups make up the majority of voters in many districts thus this  be considered a problem.

<u>Option: D</u>

<u>Explanation:</u>

Interest groups play a key role in US politics. Such organizations are made up of wealthy and powerful members who often seek to impose some form of leverage in politicians to promote their goals and agendas. Across the years via many campaigns, they have understood how to speak and manipulate elected leaders and apply leverage to get the kind of legislation that is in their favor. Here the majority of voters in several districts are standing due to group members, as we recognize the interest group belongs to a body in which it uses different methods of lobbying to influence others.

The stem of thermometer is made by thick glass and the bulb is made by thin glass, Why?​
Svet_ta [14]

Answer:

The reason is to allow the thermometer to respond relatively quickly, and relatively accurately. The glass contains the liquid being used in the thermometer, but if it is too thick, then it will not pass heat as quickly, and it will absorb some of the heat from whatever is being measured.
