Answer:
Here we have some of the requirement of practical fuel are
1. It must contain large amount of stored energy. So that more amount of power output available to run the engines, motors etc.
2. It must occur in abundance in nature or be easy to produce.
3. The fuel must be made up of elements that combine easily with oxygen. Foe example if hydrogen molecules reacts with oxygen. Then the products are at the reaction of lower energy than the reactants, the result is the explosive release of energy and the product of water.
Answer:
1 μC extra charge will be flow here
Explanation:
Given data
battery V1 = 4.0 V
flows Q1 = 6.0 μC
replace battery V2 = 7.0 V
to find out
what happen if we replace battery
solution
we apply here principal of capacitor
that is Q directly proportional voltage
so we say Q2/Q1 = V2/ V1
put all value here
Q2/Q1 = V2/ V1
Q2/6 = 7/ 6
Q2 = 7
so we see here 7 μC will be flow
and Q = Q2 - Q1 = 7 - 6 = 1 μC
so we also say that 1 μC extra charge will be flow here
It has a crystal stucture
Answer: Magnitude of electric field = 6.77×10^11N/C
Explanation: Electric field= E =KQ/ r ^2
Given:
Total charge Q=53.2nc
Radius 84cm= 0.84m
Coulombs constant K= 8.987x10^9NmC^-1
E =(( 8.987×10^9) × 53.2) /(0.84^2)
E = ( 4 . 777 ×10 ^ 9 )/ 0.7056
E = 6.77 × 10^ 11 NC^-1
