Rachel Carson was the author of the acclaimed environmental book, Silent Spring. The book was published in 1962.
It documented the negative effect that synthetic pesticides have on the environment, specifically on birds.
This book laid bare to the American public what chemical companies indirectly contributed to the environment. 
The public furor this book caused led to the reversal of the national pesticide policy, a nationwide ban on DDT for agricultural uses, and inspired the creation of the U.S. Environmental Protection Agency.

A motorcycle moving 18.8 m/s has<br> 57800 J of KE. What is its mass?
Brums [2.3K]

Answer:

m = 327.07 kg

Explanation:

Given that,

Kinetic energy of a motorcycle, E = 57800 J

Velocity of the motorcycle, v = 18.8 m/s

We need to find the mass of the motorcycle. The kinetic energy of an object is given by :

E=\dfrac{1}{2}mv^2

m is mass

m=\dfrac{2E}{v^2}\\\\m=\dfrac{2\times 57800 }{(18.8)^2}\\\\m=327.07\ kg

So, the mass of the motorcycle is 327.07 kg.

An elevator weighing 2,200 lbs is raised one story in 20 seconds. If the distance between stories is 10 feet, the power is devel
kaheart [24]

Answer: 1100 ft lb/s and 2 H.P

Explanation:

To calculate for the power developed in the elevator motor in ft.lb/s, we multiply the distance and the weight of the elevator and divide the product by the time.

                      Power = (10 ft)(2200 lb) / 20 s = 1100 ft.lb/s

Next, convert the calculated value to HP. 

                             1100 ft.lb/s x (1 HP/ 550 ft.lb/s) = 2 HP

hope this helps please give brainliest!

Miranda performed an experiment to determine what makes an object sink
NemiM [27]

Answer:

I guess the answer is

-The mass and volume of an object determine if it will sink or float

Explanation:

An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.

density=mass/volume
