Answer:
Explanation:
Since the centripetal force F_C is, in this case, the gravitational force F_G exerted by the planet, we can say that:
In the case of the satellite A we have:
And in the case of the satellite B:
Finally, using these two expressions, we obtain :
In words, the centripetal acceleration a_b is equal to one fourth of a_0.
Answer:
<u>4</u>P + <u>5</u>02 → <u>2</u>P205
Explanation:
Hence the above equation is balanced.
After the waxing gibbous, the lunar phase is the full moon so the answer is A.
B)False........... It's efficiency factor
Th equations to be used here are the following:
a = (v - v₀)/t
x = v₀t + 0.5at²
The speed of the fugitive is the sum of his own speed plus the speed of the train. Thus,
v₀ = 0 + 5.5 m/s = 5.5 m/s
v = 8 m/s + 5.5 m/s = 13.5 m/s
a.) We use the first equation to determine time
2.5 m/s² = (13.5 m/s - 5.5 m/s)t
Solving for t,
t = 3.2 seconds
b.) We use the answer in a) and the 2nd equation:
x = (5.5 m/s)(3.2 s) + 0.5(2.5 m/s²)(3.2 s)²
x = 30.4 meters
