here since string is attached with a mass of 2 kg
so here tension force in the rope is given as
here we will have
now we will have speed of wave given as
here we will have
now we know that frequency is given as
F = 100 Hz
now wavelength is given as
so wavelength will be 0.16 m
The ability to reproduce is essential for a species, but not for an individual. There are some people that can't reproduce, but they're still alive!
Vanadium is my favourite element because valadium alloys are used in nuclear reactors, valdium is also used for some ceramics and glass, its essential to some species (including humans although we need very little) an example of this is valafium is used to treat diabetes and low blood sugar
I think that the answer is friction
Well, in order to figure out the answer is to divide until you figure out how many miles they went per second. If it takes 5 seconds to reach 50 miles per hour it took 10 seconds per every 10 miles meaning each mile took 1 second. (Not actually possible but the answer) So, If it finished a 100 mile trip in 2 hours it took an hour for 50 miles. If it took 1 hour for 50 miles divide 60/50 which gets you 1.2 so it took 1.2 miles per minute meaning the car went 120 miles per hour I believe. I hope this helps :)
