The capacitance of two square parallel plates will be 1.777 farads.

<h3>What is the capacitance of two parallel plates?</h3>

The body's capacity to hold electric charge is constrained by capacitance. There is a capacitance for each capacitor. Two metallic sheets of area A, spaced by d, make up the standard parallel-plate capacitor.

The parallel plate capacitor formula is given by:

C = ε Ad

Two square parallel plates 6.7 cm on a side are separated by 1.8 mm of paraffin. The dielectric constant of paraffin is 2.2. Then the capacitance of two square parallel plates will be given as,

C = ε Ad

C = 2.2 x 0.67 x 0.67 x 1.8

C = 1.777 farad

Two parallel square plates will have a capacitance of 1.777 farads.

More about the capacitance of two parallel plates link is given below.

100 POINTS QUESTION. PLEASE PROVIDE EXPLANATION
melomori [17]

Answer:

t = 0, p = 12.0, v = 6.00

t = 20, p = 112, v = 56.0

t = 25, p = 62.0, v = 31.0

Explanation:

Impulse = change in momentum

J = Δp

FΔt = mΔv

The impulse equals the area under the F vs t graph.

At t = 0 s, the initial velocity is 6.00 m/s, so the momentum is:

p = (2.00 kg) (6.00 m/s)

p = 12.0 kg m/s

From t=0 s to t=20 s, the impulse is:

J = (20 N) (5 s) + ½ (20 N) (5 s) + ½ (-10 N) (10 s)

J = 100 Ns

So the new momentum is:

p = 12.0 kg m/s + 100 kg m/s

p = 112 kg m/s

And the new velocity is:

v = (112 kg m/s) / (2.00 kg)

v = 56.0 m/s

From t=20 s to t=25 s, the impulse is:

J = (-10 N) (5 s)

J = -50 Ns

So the new momentum is:

p = 112 kg m/s − 50 kg m/s

p = 62.0 kg m/s

And the new velocity is:

v = (62.0 kg m/s) / (2.00 kg)

v = 31.0 m/s

A heavy balloon carrying a basket is moving with a constant downward velocity of 5.0 m/s. A 1.0-kg stone is thrown from the bask
andriy [413]

Answer:98.4 m

Explanation:

Given

Descending velocity of balloon(v)=5 m/s

velocity of stone relative to balloon(u)=7 m/s

thus u is the horizontal velocity of stone and v vertical velocity of balloon

time travel by stone to reach ground=4 s

h=ut+\frac{at^2}{2}

where u=initial velocity

here u=5 m/s

t=4 s

a=g

h=5\times 4+\frac{9.8\times 4^2}{2}=98.4 m

horizontal distance traveled in this time

R=u\times t

R=7\times 4=28 m

Thus stone at distance of 28 m from balloon

Also balloon and stone will be at same height at the time when rock hits ground

A set of steel reinforcing rods is to be stretched axially in tension to create a tensile stress of 30 ksi prior to being cast i
yanalaym [24]

Answer:

13.26 kip

Explanation:

Taking diameter of the rods as 0.75 in then considering that stress is Force per unit area

Force is a product of force and area

F=A\sigma where \sigma is stress

A=\pi \frac {d^{2}}{4} and substituting this into the equation of force we get

F=\pi \frac {d^{2}}{4}

Force, F=30*pi*\frac {0.75^{2}}{4}=13.26 kip
