We need to apply the following expression
Vf = Vo + a.t
Where a is the acceleration
t is the time it takes to achieve Speed Vf
And Vo the initial speed
In this problem Vo = 60 miles/hour
Vf = 0 (comes to a stop)
t = 4 seconds
a = -60 [miles/hours] / 4 [s] = -15 miles/hour/second (negative as it goes in the opposite direction)
An organism that can make its own food is a producer. An organism that obtains energy by feeding on the other organisms is a consumer. Decomposers break down wastes and dead organisms and return the raw materials to the ecosystem.
Answer: The correct answer is-15 Volts.
Explanation-
Voltage of a battery can be defined as the difference in electric potential that lies between the positive and negative terminals of a battery.
It can be calculated using Ohm's law, which states that the electric potential difference between two points on a circuit is equal to the product of the current that flows between the two points (I) and the total resistance that sis present between the two points. It can be mathematically depicted as-
ΔV = I • R
Putting the value of 'I' and 'R', we get-
ΔV = 5 X 3
= 15 V
