In what way could a random mutation provide an organism with<br> an advantage?
andreyandreev [35.5K]

Answer:

They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time.

A current of 1.4 A flows in a conductor for 7.0 s. How much charge passes a given point in the conductor during this time?
bija089 [108]

Answer:

The charge passes a given point in the conductor during this time is 9.8 C.

Explanation:

Given that,

Current = 1.4 A

Time = 7.0 sec

We need to calculate the charge during this time

Charge :

Charge is the product of current and time.

In mathematically form,

Q = i\times t

Where, i = cirrent

t = time

Put the value into the formula

Q =1.4\times7.0

Q=9.8\ C

Hence, The charge passes a given point in the conductor during this time is 9.8 C.

A radio station broadcast on a frequency of 3.7 mhz what is the energy of the radio wave
Ratling [72]

A radio station broadcast on a frequency of 3.7 mhz what is the energy of the radio wave A radio station broadcasts its programmes at a wavelength of 500 m. Find the frequency of the radiowaves transmitted by the radio station, if the speed of radiowaves in air is 3 x 108 m/s. Ans: 6 x 10 Hz

<h3>What is radio station ?</h3>

Radio broadcasting is the act of sending audio (sound), occasionally together with accompanying metadata, across radio waves to radio receivers used by the general public. Unlike satellite radio, which uses a satellite in Earth's orbit, terrestrial radio broadcasting uses a land-based radio station to transmit radio waves. The listener needs a broadcast radio receiver to hear the material (radio). A radio network with which stations frequently have affiliations provide content in a standard radio format, whether through broadcast syndication, simulcasting, or both. Radio stations use a variety of modulations to transmit their signals, including FM (frequency modulation), which is an older analog audio standard, and AM (amplitude modulation).
