The frequency of a radio signal varies inversely with the wavelength. A signal of 800 kilohertz has a wavelength of 375 meters. What is the frequency of a radio signal of wavelength 250 meters?

The correct answer is 1200 kilohertz.

Step-by-step explanation:

Frequency of a radio signal wave is given to be inversely related to its wavelength.

Let frequency of a radio signal be f and it's wavelength be w.

f ∝

⇒ f = ; [ where k is the constant of proportionality]

⇒ f × w = k

Given wavelength and frequency of a signal is 375 meters and 800 kilohertz respectively.

Therefore the value of k = 375 × 800 = 300000

We need to find the frequency of the radio signal of wavelength 250 meters. The frequency is = 1200 kilohertz.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
