Answer:
1 second
Explanation:
h = −16t² + 32t
When, h = 16
16 = −16t² + 32t
Divide each of the numbers by 16
1 = -1t² + 2t
Rearrange the equation
1t²-2t+1 = 0
Solving by the quadratic formula, we get
So, time taken by the dolphin to jump out of the water and touch the trainer's hand is 1 second.
Answer:
V = IR
Explanation:
Voltage is denoted by V, current is denoted by I and resistance is denoted by R. Voltage is the difference of electric potential between two points. Current is the measure of the rate of flow of electric charge. Resistance is a measure how a device reduces the current flow through itself.
The three properties are related to each other as per the Ohm's law which states that voltage and current are directly proportional to each other, it can be denoted as
Voltage (V) = Current(I) X Resistance(R).
