Rachel Carson was an American marine biologist, who after the discovery of the effects of synthetic pesticides on the environment, became a conservationist.. She wrote a book called, <em>Silent Spring</em> which helped advance the worldwide environmental movement. Her book, <em>Silent Spring</em> expressed her feelings and thoughts on the environmental problems, including many problems with synthetic pesticides like DDT. <em />This then influenced a nationwide ban on many pesticides, including DDT. Her book lead to the inspiration of the grassroots movement and the creation of the U.S Environmental Protection Agency. Rachel Carson was also awarded the Presidential Medal of Freedom by Jimmy Carter.
Answer:
0.117 m
Explanation:
First of all, we can find the wavelength of the wave in the problem, by using the wave equation:
where:
v = 350 m/s is the speed of the wave
f = 500 Hz is the frequency of the wave
is the wavelength
Solving for ,
This means that the distance between two consecutive points of the wave having a difference of phase of
is 0.7 m.
Here we want to find the distance between two points that have a difference of phase of
So, we can set up the following rule of three:
where d' is the distance we are looking for. Solving for d',
No they don't. All plants are Eukaryotic/Eukaryotes.
