What must be the orbital speed of a satellite in a circular orbit 740 km above the surface of the earth?
BigorU [14]
The formula for orbital speed v is    v=(G*Me/r)^1/2
Wher G= 6.67E-11,    Me= 6E24,    r= Re+h= 6.4E6+740000
putting values in the formula we get

v= 7486.7 m/s     or  v= 7.4867 km/s

A myopic person has a far point of 1.000m. If she wears her eyeglass 2.0cm in fromt of here eyes, what is the power of her eye g
Iteru [2.4K]

Answer:

51 dioptre

Explanation:

u = Object distance =  2 cm

v = Image distance = 1 m

f = Focal length

Lens Equation

\frac{1}{f}=\frac{1}{u}+\frac{1}{v}\\\Rightarrow \frac{1}{f}=\frac{1}{0.02}+\frac{1}{1}\\\Rightarrow \frac{1}{f}=\frac{1.02}{0.02}\\\Rightarrow \frac{1}{f}=51\\\Rightarrow f=\frac{1}{51}

Power of lens

P=\frac{1}{f}\\\Rightarrow P=\frac{1}{\frac{1}{51}}\\\Rightarrow P=51\ D

Power of the eye lens is 51 dioptre.

A. a large amount of energy released into its surrounding

During the respiration, glucose molecules are converted to other molecules in a series of steps. They finally end up as as carbon-dioxide and water.

The overall reaction is

<span>C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 2805 kJ
</span>
The reaction is exothermic reaction because <span>C=O and O-H bonds in the products are so much more stable than the bonds in the reactants.
</span>
Bond energy is the average needed to break a bond.

Some bond energies are:
C-C = 347 kJ/mol
C-H = 413kJ/mol;
C-O = 358 kJ/mol;
O-H = 467 kJ/mol;
O=O = 495 kJ/mol;
<span>C=O = 799 kJ/mol</span>
