Answer:

The magnetic field strength is  B = 2 \mu T

Explanation:

From the question we are told that

             The  length line   above the ground  is  R = 20m

              The current of the line is  I  = 200A

              The voltage of the line is V = 110kV

Generally magnetic field strength is mathematically represented as

              B = \frac{\mu_o I}{2 \pi R}

Where  \mu_0 is the permeability of free space  = 4\pi * 10^{-7} N/A^2

             B = \frac{(4\pi * 10^{-7} N/A^2) *200}{2 \pi *20}

                = (2.0*10^{-7})[\frac{200}{20} ]

               = 2*10^{-6}T

              = 2 \mu T

Earths magnetic field is approximately given as 50 \mu T

   So the percentage would be

                           = \frac{Magnetic \ Field \ Intensity \ Of  \ Line}{Earth's \ Magnetic \ Field} * 100

                          = \frac{2 \mu T }{50 \mu T } * 100

                          =4%

The electrical resistance of an element in a platinum resistance thermometer at 100°c, 0°c and room temperature are 75.00Ω, 63.0
Dominik [7]

Answer:

16.6 °C

Explanation:

From the question given above, the following data were obtained:

Temperature at upper fixed point (Tᵤ) = 100 °C

Resistance at upper fixed point (Rᵤ) = 75 Ω

Temperature at lower fixed point (Tₗ) = 0 °C

Resistance at lower fixed point (Rₗ) = 63.00Ω

Resistance at room temperature (R) = 64.992 Ω

Room temperature (T) =?

T – Tₗ / Tᵤ – Tₗ = R – Rₗ / Rᵤ – Rₗ

T – 0 / 100 – 0 = 64.992 – 63  / 75 – 63

T / 100 = 1.992 / 12

Cross multiply

T × 12 = 100 × 1.992

T × 12 = 199.2

Divide both side by 12

T = 199.2 / 12

T = 16.6 °C

Thus, the room temperature is 16.6 °C

gizmo_the_mogwai [7]

Answer:

a) P1=100kpa

V1=6m³

V2=?

P2=50kpa

rearranging mathematically the expression for Boyle's law

V2=(P1V1)/P2=(100×6)/50=12m³

b) same apartment as in (a) but only the value of P2 changes

=> V2=(100×6)/40=15m³

Explanation:

since temperature is not changing we use Boyle's law. mathematically expressed as P1V1=P2V2
