Carson’s <span>“Silent Spring” influenced the environmental movement </span>as it presents a view of nature compromised by synthetic pesticides, especially DDT. The pesticides not only kill bugs but also threaten bird and fish populations, and eventually sicken children. Much of the data and case studies that Carson drew from weren’t new but she was the first to consolidate them all for the general public and to draw blunt conclusions. This book was so revolutionary that by the end of the twentieth century, it took its place on lists of the best books of the century or even of all time.

Answer:

Rachel Carson Book's "Silent Spring" changed the way people thought and treated the Earth by showing the destructive impacts of pesticide use on animal life.

Explanation:

In 1962, the American biologist Rachel Carson (1907-1964) published one of the most important works of the 20th century. Silent Spring is considered the first worldwide warning against the harmful effects of pesticide use in agriculture.  The book influenced the creation of the Environmental Protection Agency (EPA) in the United States and inspired environmental movements in several countries. But Carson's book, more than a warning against pesticides, has issued an ethical message: man's relationship with nature is on the wrong path and needs to change.

until a train is a safe distance from the station, it must travel at 5 m/s. once the train is on open track, it can speed up to
MatroZZZ [7]

Answer:

5 meters per second squared

Explanation:

We calculate the acceleration using the formula:

a = (vf - vi) / t

where "vf" is the final velocity, "vi" the initial velocity, and "t" the time it took to change from the initial velocity to the final one.

In our case:

a = (45 - 5) / 8 = 40 / 8 = 5 m/s^2

A revolutionary war cannon, with a mass of 2090 kg, fires a 16.7 kg ball horizontally. The cannonball has a speed of 113 m/s aft
OLEGan [10]

Answer:

0.90291 m/s

0.45055 m/s

Explanation:

m_1 = Mass of canon = 2090 kg

m_2 = Mass of ball = 16.7 kg

v_1 = Velocity of canon

v_2 = Velocity of ball = 113 m/s

In this system the momentum is conserved

m_1v_1=m_2v_2\\\Rightarrow v_1=\dfrac{16.7\times 113}{2090}\\\Rightarrow v_1=0.90291\ m/s

The velocity of the cannon is 0.90291 m/s

Applying energy conservation

\dfrac{1}{2}m_1v_1^2+\dfrac{1}{2}m_2v_2^2=\dfrac{1}{2}m_2v^2\\\Rightarrow m_1v_1^2+m_2v_2^2=m_2v^2\\\Rightarrow v_2=\sqrt{\dfrac{m_1v_1^2+m_2v_2^2}{m_2}}\\\Rightarrow v_2=\sqrt{\dfrac{2090\times 0.90291^2+16.7\times 113^2}{16.7}}\\\Rightarrow v_2=113.45055\ m/s

The ball would travel 113.45055-113 = 0.45055 m/s faster
