Answer:

Some of the universe's heavier elements are created by neutron star collisions. ... Light elements like hydrogen and helium formed during the big bang, and those up to iron are made by fusion in the cores of stars. Some heavier elements like gallium and bromine need something more, such as a supernova.

The U.S. Navy has long proposed the construction of extremely low frequency (ELF waves) communications systems; such waves could

Answer:

length of a quarter wavelength antenna for transmitter elf waves are zero

Explanation:

Find the length of a quarter wavelength antenna for transmitter elf waves

Given information

frequency (ELF waves) → 77Hz

Speed of light → 3 $\times$ $10^8$ m/s

$v=\lambda f-------------1$

where

$\lambda\\$ → wavelength of the antenna

f → frequency of the ELF waves

$v$ → speed of light

so rewrite the equation in $\lambda$ from

$\lambda=\dfrac{v}{f}$

Substitute $3\times10^8m/s$ = $v$

Substitute 75Hz = f

$\lambda=\dfrac{3\times10^8m/s}{77Hz}$

$=3.9\times 10^6$ m

since we get this value,but this size of antenna mount on submarine is not possible.

so $\lambda$ is zero
