Answer:

Explanation:
Given that,
Initial speed, u = 0
Final speed, v = 40 m/s
Time, t = 2 s
We need to find the acceleration of the aircraft. We know that, acceleration is equal to the rate of change of velocity. So,

So, the acceleration of the aircraft is
.

Answer:
height of the opening actually measure is 4'-9"
Explanation:
given data
window size = 3'-3" x 4'-9"
solution
height of the opening should actually measure will be 4'-9" in 3'-3" x 4'-9"
because according to architectural plan height can not be more than the opening size of window
and we can't take smaller height also
so fit in opening window we should take same height of height of opening window and that is here 4'-9"
so here height of the opening actually measure is 4'-9"
The standard unit is KW/hr, = 1,000W/hr.
(85 + 60) = 145W.
You need to find its fraction of 1,000W., so (145/1000) = 0.145 KWH.
(0.145 x 10p) = 1.45p. per hr.
