. Both can be represented by balanced equations. Both involve changes to electron arrangements in atoms. Both involve a change in energy. Both result in a change in the identities of elements.
a. v, = 630m/s,
c. v, - 1630m/s,
T = 2.78 x 10 s
T=5.78 x 10s
b. V = 1820m/s,
d. V, - 1260m/s,
T = 6.78 x 106 s
T=5.78 x 10's
Please select the best answer from the choices provid
Answer:
v = 1630 m/s
T = 5.78 x 10^5 s
Explanation:
The tangential speed of the satellite can be found by requiring that the gravitational force on the satellite is equal to the centripetal force:
where
G is the gravitational constant
M=5.97 x 1024kg is the Earth's mass
m is the satellite's mass
is the Earth's radius
is the altitude of the satellite
v is the speed of the satellite
Solving for v,
And the period of the orbit is equal to the ratio between the distance covered during one revolution (the circumference of the orbit) and the speed:
So the correct answer is
v = 1630 m/s
T = 5.78 x 10^5 s
