Answer:
Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element's isotopes. - Mass number: count of the total number of protons and neutrons in an atom's nucleus.
Explanation:
6% grade
=> Rises 6 feet for every 100 feet traveled
This would mean that tanx = 6/100.
=> x = tan^-1(6/100) = 3.4°. (1d.p.)
Hence the road is inclined at an angle of 3.4° above the horizontal.
Answer:
c. They will be shifted toward the red end of the spectrum.
Explanation:
When the absorption or emission lines of a moving object away from from the earth at very high speed then the spectral lines will be shifted toward the red end of the spectrum.This effect can be easily understand by Doppler effect..
So the our option c is correct.
c. They will be shifted toward the red end of the spectrum.
Answer:
175 m
Explanation:
In a velocity vs time graph, displacement is the area under the curve.
We can calculate this as area of a trapezoid:
A = ½ (10 m/s + 60 m/s) (5 s)
A = 175 m
Or, we can split the area into a rectangle and a triangle.
A = (10 m/s) (5 s) + ½ (60 m/s − 10 m/s) (5 s)
A = 175 m
