Answer:
Explanation:
Given data
Q₁=200cm³/s
We know that:
can be written as:
ΔP=F/A=n×v/L
And
Q=ΔP/R
As
n₂=6.0n₁
So
Q=ΔP/R
Answer:
a)Total distance = 399. 5 m
b)Total time =51.51 sec
c)Average speed = 7.75 m/s
Explanation:
For A to B:
v= u + at
8.33 = 0.42 x t
t=19.83 sec
1 Km/h=0.27 m/s
30 Km/h=8.33 m/s
s=82.6 m
For B to C
V= 8.33 m/s
s= V x t
s=8.33 x 30
s=249.9 m
For C to D
v= u - at
Final speed v=0
So
s=v x t/2
7= 8.33 x t/2
t=1.68 sec
Total distance = 82.6 + 249 .9 +7
Total distance = 399. 5 m
Total time = 19.83 + 30 + 1.68
Total time =51.51 sec
Average speed =Total distance/Total time
Average speed = 399.5/51.5
Average speed = 7.75 m/s
