Answer:
2-methylebutane
Explanation:
it is a hydrocarbon and there is a specific Rule for its nomenclature.
that is known as IUPAC naming system. According to it
- The compound that has all single bonds name ends on ane.
- Names according to the number of Carbons,
* For one carbon compound it is known as methane,
* For 2 ethane,
* For 3 propane
* For 4 Butane and so on.
- select the longest chain of compound
- Start numbering with lowest substituted position at carbon
- branch compound name as Iso and neo as whole
So keeping in mind the compound can be named as
2-methylebutane
- As the longest chain contain four carbon atoms so it will name as butane
- The substitution of methyl group is on C-2
*Note: it can also named as isopantane as it is branched and have five carbons but it could not be 3-isopentane.

Answer:

Explanation:
The relationship between the speed of a wave, its frequency and its wavelength is given by the wave equation:

where
v is the wave speed
f is the frequency of the wave, which is the number of cycles completed by the wave in one oscillation
is the wavelength, which is the distance between two consecutive crests of the wave
For the wave in this problem we have:
v = 5000 m/s is the speed
is the wavelength of the wave
Solving for f, we find the frequency:
