Answer:
32N
Step-by-step explanation:
Given data
A1= 2cm^2
A2= 16cm^2
F1= 4N
F2=???
Applying the formula
Presure= force/area
P=F/A
F1/A1=F2/A2
substitute
4/2= F2/16
cross multiply
F2= (16*4)/2
F2= 64/2
F2= 32N
Hence the output force is 32N
The explanation is here. the rest of the questions must be do by yourself.
You must subtract, add, then divide. The answer is 3.66666666667
Let x be a random variable representing the mean saraly of professors at two year institutions, then
P(x > 55000) = 1 - P(z < (55000 - 52500)/4000) = 1 - P(z < 0.625) = 1 - 0.73401 = 0.26599
Answer:
Move it to the right by 3 spaces.
Step-by-step explanation:
10^3 is 1000
On a number line the negative numbers are on the left and the positive numbers are on the right. So since the exponent is a positive 3 we move it to the right by 3 spaces to get 140
