It is A
Answer:
An online UPS
Explanation:
An online uninterrupted power supply (ups) can be defined as an electronic device that is designed to supply continuous power to a load that uses alternating current (AC), through the inverter and rectifier arrangement (combination) during normal operation of the device. Thus, an online UPS through its inverter supplies continuous AC power in the event of a power failure.
Hence, an online UPS power backup method is designed and developed to continually provide power to a server (load) if there is a power outage as a result of a thunderstorm.
In conclusion, an online uninterrupted power supply (ups) guarantees a 24 hour power supply when properly installed and connected to a load or end user device such as a server.
lst = input("Enter a,b,c: ").split(",")
a = float(lst[0])
b = float(lst[1])
c = float(lst[2])
root1 = (-b + ((b**2-(4*a*c))**0.5))/(2*a)
root2 = (-b - ((b**2-(4*a*c))**0.5))/(2*a)
dis = b**2 - (4*a*c)
if dis > 0:
print("The roots are {} and {}".format(root1, root2))
elif dis < 0:
print("The equation has no real roots")
else:
print("The root is {}".format(root1))
