If I were to go from the United States to China in one second, that's a large distance in an incredibly short time. I'd say that's pretty fast.
If I were to go from my room to the door of my room in a year, then that would be unbearably slow.
The answer is C. in sort of a way. You can't technically see black matter. However, it is holding the galaxies together.
solution:
y = v0t + ½at²
1150 = 79t + ½3.9t²
0 = 3.9t² + 158t - 2300
from quadratic equations and eliminating the negative answer
t = (-158 + v158² -4(3.9)(-2300)) / 2(3.9)
t = 11.37 s to engine cut-off
the velocity at that time is
v = v0 + at
v = 79 + 3.9(11.37)
v = 123.3 m/s
it rises for an additional time
v = gt
t = v/g
t = 123.3 / 9.8
t = 12.59 s
gaining more altitude
y = ½vt
y = 123.3(12.59) /2
y = 776 m
for a peak height of
y = 776 + 1150
The statement is not correct. Therefore, the answer is letter B. False. The actual definition of a volume variance is that it is the difference of the quantity consumed and the amount budgeted to be sold, the difference will furthermore be multiplied to the standard unit per price.
The unknown liquid has low H+ concentrations and high OH- concentrations.
