A quick USB charger claims its output current is 1.97Amp. We know that the standard USB output voltage is 5V. What is the output
1 answer:
Answer:
Output power of the charger is 9.85 watts.
Explanation:
It is given that,
Output current of the USB charger, I = 1.97 A
The standard USB output voltage, V = 5 V
We need to find the output power of the charger. It can be determined using the following formula as :
P = V × I
P = 9.85 watts
The output power of the charger is 9.85 watts. Hence, this is the required solution.

Answer:
0.11m/s
Explanation:
To solve the exercise it is necessary to apply the concepts related to the conservation of both: kinetic and spring energy(Elastic potential energy), in this way
Kinetic Energy = Elastic potential energy
Where,
m=mass
v=velocity
k=spring constant
x=amount of compression
Re-arrange the equation to find the velocity we have,
Therefore the maximum speed of the bananas is 0.11m/s
