Answer:0.853

Explanation:

Given

Reliability of A is 0.90

Reliability of B is 0.80

Reliability of C is 0.99

B has a backup with reliability of 0.8

i.e. B has a component in parallel to it.

A,B& C is series.

B actual reliability is

R_b=1-\left ( 1-0.8\right )\left ( 1-0.8\right )

R_b=0.96

Thus R_{net} is given by

R_{net}=R_A\times R_B\times R_C

R_{net}=0.9\times 0.96\times 0.99

R_{net}=0.8553

3000 N is exerted for 4.0 seconds on a 9500 kg object.<br><br> What is the change in momentum?
WARRIOR [948]
Force is the change in momentum over a specific time. The change of momentum is therefore the force multiplied by the time that the force acts, so 3000x4.0=12000 N s=12000 kg m/s
