Wood density varies depending on species, growth condition, and tree developmental stage. For example, eastern cottonwood wood has a density of about ∼320 kg/m3 while oak species often exceed ∼550 kg/m3 (Isenberg, 1980)
It would be purple. That is why it is the outside of the rainbow:)
C.an equal and opposite reaction
Answer: Only Tech B is correct.
Explanation:
First, tech A is wrong.
The circuits that can be compared with links in a chain are the series circuit, and it can be related to the links in a chain because if one of the elements breaks, the current can not flow furthermore (because the elements in the circuit are connected in series) while in a parallel circuit if one of the branches breaks, the current still can flow by other branches.
Also in a parallel circuit, the sum of the currents of each path is equal to the current that comes from the source, so Tech B is correct, the total current is equal to the sum of the currents flowing in each branch of the circuit.
Answer:
1.467 x 10^15 kg
Explanation:
Length = 160 km
width = 40 km
height = 250 m
density = 917 kg/m^3
Volume = length x width x height
Volume = 160 x 1000 x 40 x 1000 x 250 = 1.6 x 10^12 m^3
Mass = Volume x density = 1.6 x 10^12 x 917 = 1467.2 x 10^12 kg
= 1.467 x 10^15 kg
