A parallel plate capacitor above has square plates 10 cm across on each side. The plates are 50 μm apart, and the electric field

IgorLugansk [536]

Answer:

a) ΔV = 20 V , b) Q = 35.4 10⁻⁹ C, c) C = 1.77 10⁻⁹ F

Explanation:

a) The electric potential is

ΔV = E x

ΔV = 4.0 10⁵ 50 10⁻⁶

ΔV = 20 V

c) The capacity of a capacitor is

C = ε₀ A / d

The area of a square plate is

A = L²

A = 0.10²

A = 0.01 m²

L = 50mm = 50 10⁻⁶ m

Let's calculate

C = 8.85 10⁻¹² 0.01 /50 10⁻⁶

C = 1.77 10⁻⁹ F

b) the charge is

Q = C ΔV

Q = 1.77 10⁻⁹ 20

Q = 35.4 10⁻⁹ C

A box (m = 20 kg) is sliding on a horizontal surface. it is connected to a massless hook by a light string passing over a massle

Varvara68 [4.7K]

mass of the box = 20 kg

force of friction on the box due to surface

$F_s = \mu_s N$

$F_s = 0.80 * 20 * 9.8$

$F_s = 156.8 N$

similarly kinetic friction on it

$F_k = \mu_k N$

$F_k = 0.30* 20 * 9.8$

$F_k = 58.8 N$

now the weight of the suspended block will be

$W = mg = 15*9.8 = 147 N$

so here the weight of the suspended block is less than the limiting friction on it

So here we will say that friction will counter balance the weight of the suspended block and it will not move at all

So acceleration of the box will be zero

An antibaryon composed of two antiup quarks

Sveta_85 [38]

Answer:

(2) −1 e

Explanation:

A quark is the lightest elementary particles which form hadron such as proton and neutron. A quark has fractional charge.

Up, charm and top quarks have $+\frac{2}{3} e$ charge where as down, strange and bottom quarks have $-\frac{1}{3}e$ charge.

The antiparticle of up quark is antiup quark and has charge $-\frac{2}{3}e$ charge.

The antiparticle of down quark is antidown quark and has charge $+\frac{1}{3}e$ charge.

An antibaryon is composed of two anti-up quark and one anti-down quark.

Net charge of the anti-baryon is:

$2\times (-\frac{2}{3} e)+1\times (+\frac{1}{3})e=-1e$

Thus, antibaryon has -1e charge.

Whats a good air time and maximum height

serg [7]

Answer: Time to reach max. height is the time taken by it to reach the topmost position whereas time of flight is the overall time taken by it, i.e. till it reach down back to the thrower or launcher. And also time of flight is double the time to reach maximum height.
