A constant-volume perfect gas thermometer indicates a pressure of 6.69 kPa at the triple point temperature of water (273.16 K).

mina [271]

Answer:

(a) ΔP=0.0245 kPa

(b) P=9.14 kPa

(c)ΔP=0.0245 kPa

Explanation:

(a) As it is perfect gas we can use

(P₁V₁)/T₁=(P₂V₂)/T₂

Since this constant volume so

P₁/T₁=P₂/T₂

T₂ is change in temperature

T₂=1.00+273.16

T₂=274.16 K

$P_{2}=(\frac{6.69}{273.16} )*274.16\\P_{2}=6.71449 kPa$

ΔP=6.71449-6.69

ΔP=0.0245 kPa

(b) As

$P_{2}=(\frac{6.69}{273.16} )*373.16\\P_{2}=9.14 kPa$

(c) Same steps as in part (a)

$P_{2}=(\frac{9.14}{373.16} )*374.16\\P_{2}=9.164kPa$

ΔP=9.164-9.14

ΔP=0.0245kPa

A very long insulating cylinder of charge of radius 2.50 cm carries a uniform linear density of 15.0 nC/m. (

Pavlova-9 [17]

Answer:

r2 = 2.401557 cm

distance = 0.10 cm

Explanation:

given data

radius = 2.50 cm

density = 15.0 nC/m

voltmeter read = 175

solution

we know here potential difference that is express as

ΔV = $\frac{\lambda }{2\pi \epsilon _o} ln\frac{r2}{r1}$ ...........1

so here

$ln\frac{r2}{r1} = 2\pi \epsilon _o \times \frac{\triangle V}{\lambda }$

as here $\lambda$ is linear charge density

$\frac{r2}{r1} = e^{2\pi \epsilon _o \times \frac{\triangle V}{\lambda }}$

r2 = r1 × $e^{2\pi \epsilon _o \times \frac{\triangle V}{\lambda }}$

r2 = 2.40 × $e^{2\pi 8.85\times 10^{-12} \times \frac{175}{15\times 10^{-6} }}$

r2 = 2.401557 cm

and

here distance above surface will be

distance = r1 - r2

distance = 2.50 - 2.40

distance = 0.10 cm

______ is an offer to repair or replace a product if there is a problem with the product?

ANTONII [103]

<span>A warranty is an offer to repair or replace a product if there is a problem with the product. Warranties are written guarantee issued to the consumer by the manufacturer at the time of purchase, promising to repair or replace a faulty material. It is usually based on the premise that the product is free from defects in materials and workmanship. It claims that the manufacturer constructed the product out of proper materials, and would compensate the consumer should there be any defects. The period to file a claim typically varies. Some manufacturers place a 90 day period, some a year and a few, even more.</span>

Explain why the temperature varies with distance from the Sun in this way?

GenaCL600 [577]

Answer:

The average surface temperature decreases the further you get from the Sun because the more distant planets receive less energy/heat/sunlight per square meter of their surface. This is because the energy from the Sun spreads out (becomes less concentrated) as you travel further from the source/Sun.
