Answer:
The cost of energy is 0.29$.
Explanation:
Given that,
Voltage V= 12 V
Charge Q= 160 A-h
We need to calculate the energy
Using formula of energy
Where, E = energy
I= current
V = Potential
t = time
Put the value into the formula
The cost of this energy at 0.15/kwh
Here, Energy = power x time
In units,
But , Energy in 1 hour is:
So, The cost of this energy is
Hence, The cost of energy is 0.29$.
Answer:
The parachute to open in 15 sec.
Explanation:
Given that,
Velocity = 120 km/hr
Height = 1000 m
If his parachute must open 500. m above the ground.
We need to calculate the time for parachute to open
Using formula of time
Where, d = distance
t = time
v = velocity
Put the value into the formula
Hence, The parachute will be open in 15 sec.
