P = kq/r
5 = k*1/2
k = 2*5 = 10
p = 5*10/50 = 1
P is 1.

Answer:
height of the wall = 9.79 m
Step-by-step explanation:
This form a right angled triangle.
Hypotenuse = length of the ladder = 10 m
Base = length from foot of ladder to wall.
Altitude = height of the wall
Pythagorean's theorem,
base² + altitude² = hypotenuse²
2² + altitude² = 10²
4 + altitude² = 100
altitude² = 100 - 4
altitude² = 96
altitude = √96 = 9.79 m
Answer:
CBD=63
Step-by-step explanation:
Since ABD is the total angle which contains CBD and ABC, ABC+CBD=96. With this, you can set up an equation.
6x+27+7x-9=96
13x+18=96
13x=78
x=6
6x+27=6(6)+27=36+27=63 degrees. Hope this helps!
Answer:
the standard deviation of the critical path is 8
Step-by-step explanation:
The computation of the standard deviation of the critical path is shown below:
As we know that
Variance = Standard deviation^2
Now the variance of the critical path is
= Variance 1 + variance 2 + variance 3 + variance 4
= 4^2 + 4^2 + 4^2 + 4^2
= 64
Now the standard deviation would be
= √64
= 8
hence, the standard deviation of the critical path is 8
