The answer would be 981 newtons or 220.46 pounds.
Answer:
923.44N
Explanation:
Obviously Fn cannot equal Fg since the elevator is moving up
Where Fn is the force read on the scale
Fg is gravitational force=mg=77.6 x 9.8=760.48N
So we use this equation:
Fnet = Fn - Fg
ma = Fn - mg
77.6 x 2.1 = Fn – 760.48
162.96N = Fn – 760.48N
923.44 N = Fn
The answer is 923.44 N
Answer:
A ruler.
Explanation:
Just measure height, length and width and multiply each.
Beats are generated by two interfering waves when they have slightly different frequencies.
Answer:
"Crust" refers to a
terrestrial planet's outermost surface.
In general, the Earth's crust is divided into
older, thicker continental crust and younger, denser oceanic crust.
...
The thin, 40-kilometer (25-mile) deep crust of our planet — just
1 per cent of Earth's mass — contains all known universe existence.
Explanation:
Continental crust is thicker, 22 miles (35 km) on average and less dense than oceanic crust, which accounts for its mean surface elevation of about 3 miles (4.8 km) above that of the ocean floor (Archimedes’ principle). Continental crust is more complex than oceanic crust…
