Nonpoint* source pollution does come from a variety of locations, but it is NOT easy to trace. This statement is false.
Answer:
The maximum distance compressed by the spring = 0.126 m
Explanation:
k = 1600 N/m
Given,
Mass of book = 1.40 kg
Height book above the spring = 0.80 m
Let the maximum distance the spring will be compressed be x
The change in potential energy of the book = workdone in compressing the spring by a Maximum distance of x
Change in potential energy of the book moving through height 0.80 m and a distance of x is given as
= mg(0.8 + x) = 1.40 × 9.8(0.8+x)
= 13.72(0.8+x) = (10.976 + 13.72x) J
Workdone in compressing the spring by a distance of x = (1/2)(1600)(x²) = (800x²) J
10.976 + 13.72x = 800x²
800x² - 13.72x - 10.976 = 0
Solving the quadratic equation
x = 0.126 m or - 0.108 m
The answer that supports the question according to the laws of Physics = 0.126 m
The maximum distance compressed by the spring = 0.126 m
Hope this Helps!!
Venus has the slowest rotation rate.
It takes Venus 243.7 Earth days to rotate once.
Planet Period
Venus 243.7 (Earth) days
Mercury 58.8 days
Pluto 6.4 days
Mars 24.6 hours
Earth 23.9 hours
Uranus 17.2 hours
Neptune 16.1 hours
Saturn 10.7 hours
Jupiter 9.9 hours
Interesting . . . the largest planet rotates the fastest.
I wonder why that is.
Answer:
A package is dropped from a helicopter moving upward at 15 m/s. If it takes 16.0 s before the package strikes the ground, how high above the ground was the package when it was released? (Disregard air resistance.)
Show step by step please.
Note: The answer is given it's should be 1000 m ??
This what i can up with so see what it is kid
