Answer:
Electrons are retained by the electromagnetic force in the orbit around the nucleus since the nucleus is positively charged in the middle of the atom and absorbs the electrons charged negatively.
Hope this helps!
The sun is at the solstices on roughly June 21 and December 21.
June 21 is the "Summer" solstice in the Northern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Cancer, about 23.5° North of the equator.
December 21 is the "Summer" solstice in the Southern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Capricorn, about 23.5° South of the equator.
D. They are heterotrophs that digest food internally.
A) Using:
2as = v² - u², where v will be 0 at max height
s = -(160)² / 2 x -32.174
s = 397.8 ft
b) Using:
s = ut + 1/2 at²
256 = 160t - 16.1t²
solving for t,
t = 2.0, t = 7.9
Now, v = u + at, for both times:
v(2) = 160 - 32.174(2)
v(2) = 95.7 ft/sec on the way up
v(7.9) = 160 - 32.174(7.9)
v(7.9) = -94.3 ft/sec; 94.3 ft/sec on the way down
c) -32.174 ft/s², which is the acceleration due to gravity.
d) s = 0
0 = 160t - 1/2 x 32.174t²
t = 9.94 seconds
Answer:
3.26mph
Explanation:
To calculate speed, use the formula distance/time. In this case, just divide 14.7 by 4.5.
