As you know, g = 9.81 m/s on the surface of the Earth. ... If the action force is the force she exerts downward on the chair, what is the reaction force? ... it take a 10-N force to increase the speed of a 10-kg toy car from 1.00 m/s to 4.00 m/s? ... (DH 32) How many joules of kinetic energy does a .5 kg cart have when it is ...
Step-by-step explanation:
Answer:
r = I/P*t
Step-by-step explanation:
So I dont know how to explain it but to show you how to do it.
I = Prt
Divide both sides by Pt to get r alone

Therefore your answer is r = I/P*t
Hopes this help :)
Answer:
1/5
Step-by-step explanation:
Range as a measure of central tendency is the difference between the highest value and the lowest value in a given set of data.
Given the samples 0,1,3,4,7
Total number of samples is 5
The range is gotten by taking the difference of 2 samplesout of 5samples and this can be done in 5C2 ways.
5C2 = 5!/(5-2)!2!
= 5!/3!2!
= 5×4×3!/3!×2
= 10ways
The total outcome is therefore 10
To get the probability that the range is 4, we need to get the required outcome of getting range of 4 and this can only occur twice
The range can be gotten by taking the difference between 7 and 3, it can also be gotten by taking the difference between 4 and 0. Both differences will give us a total of 4
The expected outcome is therefore 2
the probability that the range of the sample is 4 = expected outcome/total outcome
= 2/10
= 1/5
