Calculate the amount of heat (in kj) required to convert 74.6 g of water to steam at 100°c
Kryger [21]
You just need the energy of turning of water in to steam. Water is a little funny because once water gets to 100 degrees C, it stops changing in temperature whilst it all turns to steam. The amount of energy required to turn 1 gram of water into steam is 2257 Joules. We call this the latent heat of vaporisation. So to turn 74.6 grams of water to steam, you would need:

2257J/gram x 74.6g = 168,372.2 J = 168.4 kJ

(<span></span><em>latent heat of vaporisation: 2257 J/gram</em>)

A 2000 kg streetcar parked in a lot has a larger momentum than a 1000 kg car going 25 meters per second on the highway.
Arturiano [62]

Answer:

Other than the fact that momentum is a "vector" quantity I wouldn't know.

If the car had a momentum opposite to the chosen positive direction then its total momentum would be negative.

Where does Amino acid come from?
Vesna [10]

Answer:

The best sources of essential amino acids are animal proteins like meat, eggs and poultry. When you eat protein, it's broken down into amino acids, which are then used to help your body with various processes such as building muscle and regulating immune function ( 2 ).

A cube has height of 3cm. What is the volume of the cube?
Arisa [49]

Answer:

27cm^{3}

Explanation:

The formula to find the volume of a cube is Volume=height cubed(or to the power of 3) so you would replace height with 3cm and get the equation Volume= 3 to the power of 3. So 3 x 3 x 3 = 27. So your answer would be:

27cm^{3}

8. Two spheres of mass 2 kg and 3 kg respectively are situated so that the gravi- tational force between them is 2,5 x 10-8 N. C
wlad13 [49]

<u>Question</u> :-

  • Two spheres of mass 2 kg and 3 kg respectively are situated so that the gravitational force between them is \bf 2.5 \times 10^{-8 }NCalculate the distance between them.

<u>We are given </u>:-

  • Mass of first sphere, m = 2 kg
  • Mass of second sphere, M= 3 kg
  • Gravitational force ,F = \bf 2.5 \times  10^{-8} N
  • G = 6.67×10⁻¹¹ Nm²/kg²

We are asked to find distance between them.

  • We know that according to gravitational law, we have force of attraction between two bodies is directly proportional to the product of masses of bodies and inversely proportional to the square of distance between them.Which is given by –

\qquad \pink{\twoheadrightarrow\sf F = \dfrac{GmM}{r^2}}

<u>Substituting values, we get</u> –

\qquad \twoheadrightarrow\sf  2.5\times 10^{-8} = \dfrac{6.67\times10^{-11}\times2\times3}{r^2}

\qquad \twoheadrightarrow\sf  2.5\times 10^{-8} = \dfrac{4.002\times10^{-8}}{r^2}

\qquad \twoheadrightarrow\sf  \dfrac {r^2}{4.002\times10^{-10}}=\dfrac{1}{2.5\times10^{-8}}

\qquad \twoheadrightarrow\sf   r^2 = \dfrac{4.002\times10^{-10}}{2.5\times10^{-8}}

\qquad \twoheadrightarrow\sf   r^2 = 1.6 \times 10^{-10}\times 10^{8}

\qquad \twoheadrightarrow\sf   r^2 = 1.6 \times 10^{-10+8}

\qquad \twoheadrightarrow\sf   r^2= 1.6\times10^{-2}

\qquad \twoheadrightarrow\sf   r=\sqrt{1.6\times10^{-2}}

\qquad \twoheadrightarrow\sf   r=1.265\times10^{-1} \: m

\qquad \pink{\twoheadrightarrow\bf  r = 12.65 \:cm}

  • Henceforth,distance between them will be 12.65 cm.
