We are given with the data that says the probability that a battery will last 10 hr or more is 0.8 and the probability <span>that it will last 15 hr or more is 0.11. In this case, the probability that the battery lasts at least 10 hours and even 15 hrs more is 0.11 / 0.8 or equal to 13.75 percent.</span>
Explanation:
Static friction is a type of friction in which two objects don't move relative to each other. The force due to static friction is given by :
N is normal force
is coefficient of static friction
For the kinetic friction, the force becomes :
