Howdy!!
your answer is ----
total resistance 1/R = 1/9+1/9+1/9
= 3/9
=> R = 9/3 = 3 ohm
according to ohms law
voltage = current × resistance
= 4 × 3 = 12 volt
hope it help you
Mass and energy are inter convertible.As per Einsteins mass and energy relations i.e 
,some amount of energy is lost that is converted into energy .
In our day to day life ,generally mass is lost and energy is formed. In a ideal assumption we subtract the mass of earlier one from the later one which indirectly denotes that some amount of mass is lost and energy is released .There is also endothermic reactions where energy is needed which does not mean mass is added.Here simply energy is needed to initiate the reactions.
So instead of subtracting the smaller value from lager we subtract the initial value from final as the latter one can explain a physical phenomenon in a better way.we can get some in formation from it.
Hello There
Answers:
1) BEVs and hydrogen fuel cell vehicles are more promising for the future because they reduce gas emissions as well as CO2 which makes our planet less-pulluted
2) This is an opinion. Mine is that they should be required to at least have it be an option to buy.
I hope this helps

Answer:
a = 39.8 m/s²
Explanation:
Centripetal acceleration is the acceleration that changes the direction of a body's speed without changing its module.
a = v² / r
With the module is constant we can use the equations of uniform motion to find the speed
v = d / t
Where the distance d is the circle length
d = 2π r
Where r is the distance from the moon to the surface of the plant plus the radius of the plant
r = 255.0 10⁶ +3.1 10⁶ m
r = 258.1 10⁶ m
The time it takes to make a full turn is called a period
t = T = 16 10³ s
Let's replace and calculate centripetal acceleration
v = 2π r / T
calculate
a = (2π r / T)² / r
a = 4π² r² / T²r
a = 4π² r / T²
a = 4π² 258.1 106 / (16 103)²
a = 39.8 m/s²
