Equate the gravitational force to the electrostatic force:
<span>KC²/D² = Gm²/D² → C = m√[G/K] = 7.6√[6.67E-11/9E9] = 6.54E-10 coulombs </span>
<span>Number of electrons N = 6.24E18*C = 4.083E9 electrons</span>
Answer:
inertia is the tendency of an object to resist a change
<span>D - Windex contains ammonia and other dangerous chemicals </span>
1)Agricultural wastes will not be available if the basic crop is no longer grown. 2)Additional work is needed in areas such as harvesting methods. 3)Land used for energy crops maybe in demand for other purposes, such as faming, conservation, housing, resort or agricultural use. 4)Some Biomass conversion projects are from animal wastes and are relatively small and therefore are limited. 5)Research is needed to reduce the costs of production of Biomass based fuels. <span>6)Is in some cases is a major cause of pollution.</span>
Answer :
(a) The speed of light in km/hr is, 
(b) The speed of light in mi/min is, 
Explanation :
(a) We are given the speed of light is, 
As we know that,
and,
By using both the conversion, we get:
The speed of light in km/hr is,
(b) We are given the speed of light is,
As we know that,
and,
By using both the conversion, we get:
The speed of light in mi/min is,
