Answer:
Option b = "is stored in ROM to ensure to avoid any infection from viruses. "
Explanation:
In order to to understand the fundamentals of an Operating system in computer one needs to know what the bootstrap program is.
The BOOTSTRAP PROGRAM is first program that will run when the computer is switched on, thus the program( the BOOTSTRAP PROGRAM) will be the program to open the OPERATING SYSTEM.
The device in laptops and personal computers known as ROM is an acronym that stands for Read-Only Memory and it is a storage medium. Because of ROM inability to get Virus it is used in the storage of Bootstrap program.
Answer:
vw = fλ
Explanation:
Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength. You can observe direct evidence of the speed of sound while watching a fireworks display. The flash of an explosion is seen well before its sound is heard, implying both that sound travels at a finite speed and that it is much slower than light. You can also directly sense the frequency of a sound. Perception of frequency is called pitch. The wavelength of sound is not directly sensed, but indirect evidence is found in the correlation of the size of musical instruments with their pitch. Small instruments, such as a piccolo, typically make high-pitch sounds, while large instruments, such as a tuba, typically make low-pitch sounds. High pitch means small wavelength, and the size of a musical instrument is directly related to the wavelengths of sound it produces. So a small instrument creates short-wavelength sounds. Similar arguments hold that a large instrument creates long-wavelength sounds.
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. The wavelength of a sound is the distance between adjacent identical parts of a wave—for example, between adjacent compressions as illustrated in Figure 2. The frequency is the same as that of the source and is the number of waves that pass a point per unit time.
Answer:
Time management,
Refreshment,proper input, Need of energy,prioritization.
Answer:
Rick has identified a cost risk.
Explanation:
Risk is the probability of loss in a given setting. Herein, the risk involved is the inadequate assessment of the costs involved to carry out the project usually as a result of poor pricing evaluation of resources required for the project. At the early stage of every project, effective and efficient cost estimation is needed because it provides a basis for estimation of the total costs, it helps distribute the cost budget, it eases decision making and thereby assuring a level of profitability, everything being equal.
Answer:
The loop counts the count() function length of n-1 times with respect to n.
Explanation:
The first and outer loop counts for two times as the variable declared in the condition counts before the iteration is made. The same goes for the other for statements in the source code.
The n represents the number length of a range of numbers or iterables (like an array).
