Speed is different from velocity. Velocity is a vector quantity and has a direction. Speed is a scalar quantity and does not require a direction. The answer must be D).
Answer:
See the answer Explain why aircraft are carefully designed so that parts do not resonate. Expert Answer This virtually takes place, however maximum usually in small piston-engined airplanes, in particular dual-engined airplanes. The resonant frequency of the fuselage of a small plane goes to have numerous nodes, withinside the low loads of hertz.
infiltration and evaporation
Data given:
V=45m/s
t=11s
Δx=?
Formula needed:
V=Δx/t
Solution:
Δx=v×t
Δx=45m/s×11s
Δx=495m
According to my solution B) is the most accurate
Answer:
Explanation:
This is an excellent question to get an answer for. It teaches you much about the nature of physics.
The answer is no.
The distance will be quite different. The time might be different in getting to the distance. But the acceleration will be the same in either case.
How do you know? Look at one of the formulas, say
d = vi * t + 1/2*a * t^2
What does vi do? vi will alter both t and d. if vi = 0 then both d and/or t will be found. But what will "a" do? Is there anything else acting in the up or down line of action? You should answer no.
If vi is not zero, t will be less and d will take less time to get where it is going.
