Answer:

3 Volts

Explanation:

Because Power = Voltage x Current, so if you substitute the values into the equation, it would be :

2.4 W = Voltage x 0.8 A

Then if you rearrange the equation, it would be :

2.4 W / 0.8 A = Voltage

Which is :

3 V = Voltage

Viktor [21]

Answer:

The program only runs 5 five since the for loop statement is limited to loop only five times.

Explanation:

In programming, a for-loop statement is used to repeat a collection of events a definite number of times. The number of loops is specified and compared with a variable to execute a block of code.

The for-loop statement in the code above declares and initializes a variable "i" to zero, runs the block of code, and increments by one if it is less than 5.

To make it run eight times, the value five should be changed to 8 instead.

Where must virtualization be enabled for VM (virtual machine) software to work?
Lelu [443]

Answer:

b) BIOS/UEFI

Explanation:

Virtualization can be defined as a technique used for the creation of a virtual platform such as a storage device, operating system, server, desktop, infrastructure or computing resources so as to enable the sharing of resources among multiple end users. Virtualization is usually implemented on a computer which is referred to as the "host" machine.

Generally, virtualization must be enabled in the BIOS/UEFI for VM (virtual machine) software to work.

BIOS is an acronym for Basic Input/Output System while UEFI is an acronym for Unified Extensible Firmware Interface. BIOS/UEFI are low-level software that serves as an intermediary between the operating systems and the computer's firmware or hardware components. The UEFI is actually an improvement of the BIOS and as such is a modernized software.

Basically, the BIOS/UEFI is a software which is an essential tool or feature which must be enabled to link the virtual machine with the hardware components of the computer.
