Answer:

95^{\circ} C

Explanation:

In reference to the book called College Physics the first edition, the back of the textbook, precisely table 13.5 gives various vapour pressure and saturation density of water at different temperatures. For this case, considering the pressure given, the table shows that the temperature of 95^{\circ} C is when water boils considering the altitude given.

If v lies in the first quadrant and makes an angle Ï/3 with the positive x-axis and |v| = 4, find v in component form.
Alexeev081 [22]

Answer:

v=

Explanation:

We are given that

Magnitude of vector v=\mid v\mid =4

v lies in the first quadrant

\theta=\frac{\pi}{3}

v_x=\mid v\mid cos\theta

v_y=\mid v\mid sin\theta

Substitute the values then we get

v_x=4cos\frac{\pi}{3}

v_x=4\times \frac{1}{2}=2

cos\frac{\pi}{3}=\frac{1}{2}

v_y=4\times sin\frac{\pi}{3}=4\times \frac{\sqrt 3}{2}=2\sqrt 3

sin\frac{\pi}{3}=\frac{\sqrt 3}{2}

Therefore, the vector v in component form=

A skier skies down a slope with an average speed of 50 km/s. How far does the skier travel in 5 minutes?
aliya0001 [1]

Answer:

15000000 m

Explanation:

From the question,

Speed (S) = Distance(d)/Time(t)

S = d/t....................... Equation 1

Make d the subject of the equation

d = St..................... Equation 2

Given: S = 50 km/s = 50000 m/s, t = 5 minutes = 5*60 seconds = 300 seconds

Substitute these values into equation 2

d = 50000(300)

d = 15000000 m

Hence the skier travels 15000000 m

An electronics technician wishes to construct a parallelplate capacitor using rutile (k=100) as the dielectric. The area of the
My name is Ann [436]

Given k=100, Area if plate A = 1.00 cm2

    = 1 x (10-2)2 m^{2}

Thickness of rutile ds = t = 1.00 mm

      = 1 x 10-3 cm

Without any dielectric medium capacitance of a parallel plate capacitor is c = oAd

When a dielectric is placed between capacitors plates then capacitance c1 = KoAd

Here d = t = 1 x 10-1 cm, o = 8.854 x 10-12 c^{2} m^{-2}  N

Now c1 = 100 X 8.859 X 10^{-12}  X 1 X (10-2)^{21}  X 10^{-2}

= 8.859 X 10-1910-3= 8.85 X 10-11 F= 8.85 X 10-12 F

 C1  = 88.5 X 10-12 F

 C1  = 88.5  PF

Correct Option: A

What purposes serve parallel plate capacitors?

The following are some uses for parallel plate capacitors:

  • This kind of capacitor is utilized in rechargeable energy systems such as batteries.
  • These capacitors are used in systems for dynamic digital memory.
  • Such capacitors are used in pulsed laser and radar circuits.
