Answer:
The price per kWh is
The energy density in watt-hours per lb is
Explanation:
From the question we are told that
The voltage of the battery is
The capacity of the battery is
The price is
The weight of the battery is
Generally the energy generated by the battery is mathematically represented as
Here P is power which is represented as
So
=>
=>
=>
converting to kW h
=>
=>
Generally the cost of this energy produced is Hence the cost of 1 kWh is mathematically represented as
=>
=>
Generally the energy density is mathematically represented as
=>
=>
I would say, none of them is correct.
Because W= F.d, Here it is read: Work equals Force dot distance. It is a dot product not a cross product.
But for this question, if you have to choose something. Choose W=Fxd.
Hope this helps.
Answer:
When the metal is dropped in the solution it turns blue to green because this forms iron sulphate solution and turns the metal copper
Iron sulphate + copper
Answer: The velocity is 21.5m/s
Explanation:
Let's call:
M1 and V1 as the mass and velocity of the falcon:
M1 = 1.45kg
V1 = 26.5m/s
M2 and V2 as the mass and velocity of the dove:
M2 = 0.415kg
V2 = 4.35m/s
Where both velocities are positive because both animals move in the same direction.
We can think that the interaction between both animals is a perfectly inelastic collision, because afther the interaction they move as one. Then, we have that the final velocity of both animals togheter is:
V = (V1*M1 + V2*M2)/(M1 + M2)
V = (1.45kg*26.5m/s + 0.415kg*4.35m/s)/(1.45kg + 0.415kg) = 21.5m/s
Velocity was slowing, it was going down
