Answer: The radio should be tuned to 100. 0 Mhz.
Explanation:
As radio waves are electromagnetic waves, like x-rays, UV rays, and all the wavelengths of visible light, they propagate in the free space at the speed of light: 3. 10⁸ m/s.
At any wave, there is a fixed relationship between the distance travelled by the wave along one cycle (which is called wavelength ) and the speed at which the wave oscillates (which is called the frequency of the wave), with the speed at which the wave propagates, as follows:
λ (wavelength) = v (speed) / f (frequency)
Replacing by the values, and solving for frequency, we have:
f = 3. 10⁸ m/seg / 3 m = 10⁸ 1/sec = 10⁸ Hz = 100. 0 Mhz
This is the radio channel to which must be tuned in order to listen the station with a wavelength of 3 m, in the FM band.
It does not work that way....I thought the same thing. The sound will always come out of your iPhone
Answer:
Option D is the correct answer for the above question.
Explanation:
Email list (as the name suggests) is defined as the set of an Email address. It is also the group of address which is needs for message distribution because an Email address is the only necessary part to send the mail which is also called the message. When a user wants to send the mass Email or message then he needs a list of email which can be filled at the "TO" or "CC" or "BCC" part of the compose mail and it can be able to send the mass message.
The above question asked about the list which is useful for the mass message then the answer is an Email list which is stated from the option D. Hence option D is the correct answer while other is not because--
- Option A states the actor list which is not required to send the mail.
- Option B states the client list which is not required to send the mail.
- Option C states the chat list which is not required to send the mail.
less time and depth is required for panel discussions
Answer:
D. Flash the BIOS
Explanation:
The function of the BIOS is to test all computer hardware that is attached to a machine before loading the operating system. Since the bios contains firmware that enables the configuration of computer hardware. when the 2 TB hard drive is connected the technician should update the program stored on the BIOS chip in other words flash the bios for it to be able to read the new hard drive. Reinstalling the drive will not make a difference as long as the BIOS still detects the 250 GB hard drive.
