The answer is 1. 4 is incorrect because you can't really decrease the mass of the driver. 3 is incorrect because accelerating the driver would cause more damage than not. 2 is incorrect because decreasing the distance would only cause more damage. 1 is correct because by increasing the length of time the force acts on the driver helps reduce the speed of the driver and cause the drive to sustain less injuries. Hope that helps.
constant non zero acceleration
Answer:
Option C. Rate of change of velocity
Explanation:
To know the correct answer to the question, it is important we know the definition of power.
Power can be defined as the rate at which work is done. Mathematically, it is expressed as:
Power = work / time
Work and energy has the same unit of measurement i.e joule. Thus, power can also be defined as the rate at which energy is transferred i.e
Power = enery / time
Energy is measured in Joules and time in second. Thus, power can also be defined as amount of joules transfered per second.
Power = Joule / sec
The rate of change of velocity on the other hand is termed acceleration.
Thus, the answer to the question is option C.
Answer:A) Risk(R)= $1000
B) There is justification for spending an additional cost of $100 to prevent a corrosion whose consequence in monetary terms is $1000
Explanation:R= Risk,
P=Probability of failure
C= Consequence of failure
Mathematically, R=P ×C
10 out of 1000 carbon-steal products failed
Probability of failure= 10/1000 =0.01
The consequence of failure by corrosion given in monetary term =$100,000
Risk of failure = 0.01 × $100,000
R=$1000
