The cost of the 1.4KW kettle is 0.945 p.

<h3>What is the cost of electricity?</h3>

The cost of electricity is computed from the cost of electricity. We have to know the cost of electricity that is charged for the 1.4kW kettle.

Now let the power consumed=

1.4kW * 0.075 hrs = 0.105 KWhr

Then;

1 KWhr costs  9p

0.105 KWhr costs 0.105 KWhr *  9p/1 KWhr

= 0.945 p

1The specific heat of substance (X) is greater than that for substance (Y). If equal amounts of heat are added to both these sub
geniusboy [140]

Answer:

Substance Y

Explanation:

A substance with a high specific heat capacity can absorb a large quantity of heat before it will raise in temperature.  A substance with a low specific heat requires relatively little heat to raise its temperature. Thus, if the same amount of energy was added to both substances, substance Y will reach the higher temperature, while substance X would require more energy to reach high temperatures.

A 2.0-cm-diameter parallel-plate capacitor with a spacing of 0.50 mm is charged to 200 V?
SpyIntel [72]

Answer:

U= 0.112 x10^{-6} J

u= 0.708 \frac{J}{m^{3} }

Explanation:

diameter= 2 cm

r= 1 cm * \frac{1m}{100cm} = 0.01 m

distance= 0.5 mm

d= 0.5 mm * \frac{1m}{1000m}= 0.5 x10^{-3}

Area A= \pi *r^{2}= 0.314x10^{-3}  m^{2}

Volume v= A*d = 0.314 x10^{-3}m^{2}*0.5x10^{-3} m =0.157x10^{-6}  m^{3}

v= 0.157 x10^{-6} m^{3}

Constant vacuum permittivity

E_{o}= 8.85x10^{-12}

a).

C= \frac{A*E_{o} }{d} = \frac{0.314x10^{-3} *8.85x10^{-12}  }{0.5x10^{-3} } \\C= 5.56 x10^{-12}F

U= \frac{1}{2} *C *V^{2}\\ U=\frac{1}{2} * 5.56x10^{-12}*(200)^{2}  \\U=0.112 x^{-6} J\\

b).

u=\frac{U}{v}

u=\frac{0.112 x10^{-6}J}{0.157x10^{-6}m^{3}  } \\u=0.708 \frac{J}{m^{3} }

The puffin is a bird that lives__________the sea.
Gnesinka [82]
What I found was from another website and it said "For most of the year, Atlantic puffins live on the open ocean, with a range spanning from the eastern coast of Canada and the northern United States to the western coast of Europe and northern Russia. 60% of the world's puffins live near Iceland. Puffins are specially adapted to living<span> on the open sea." here is the link https://animalfactguide.com/animal-facts/atlantic-puffin/

I put the link and a picture so it hopefully won't be deleted for plagiarism.
