Trees are renewable resources because they can be replaced in a single lifetime and are replaced faster than they are harvested and used.
It can be maintained by responsible harvesting and use. One policy that many lumber companies advertise is that they plant a seed for every tree that they chop down.
Hope this helps! :)
The force of a spring can be calculated by the expression:
F = kx where k is a constant and x is the distance.
From the problem statement, we can solve the value of k from the initial conditions given as F = 25 N and x = 2 cm.
25 = k (0.02)
k = 1250
We use the work formula which is force times the distance resulting to the expression:
W = (1/2)(kx^2)
W = (1/2)(1250)(0.03^2)
W = 0.5625 J
Under STP 1 mol of gas has volume 22.4 L.
2C2H2 + 5O2 ------> 4CO2 + 2H2O
from reaction 5*22.4 L 4 *22.4L
given 60L x L
x=(60*4 *22.4)/5*22.4 = (60*4)/5 =48 L of CO2
Answer:
i believe the grand canyon is an example
Explanation:
Answer:
pH = 4.44
Explanation:
You take the negative logarithm of the hydronium ion concentration.
pH = -log[H₃O⁺] = -log(3.6 × 10⁻⁵) = 4.44
