Answer:

<u>distance</u><u> </u><u>between</u><u> </u><u>should</u><u> </u><u>be</u><u> </u><u>1</u><u>.</u><u>2</u><u>5</u><u> </u><u>×</u><u> </u><u>1</u><u>0</u><u>^</u><u>6</u><u> </u><u>m</u>

Explanation:

Force is proportional to separation distance.

250 \: newtons = 2.5 \times  {10}^{6}  \: metres \\ ( \frac{1}{2}  \times 250) \: newtons = d \\  \\ d =  \frac{125 \times 2.5 \times  {10}^{6} }{250}  \\ d = 1.25 \times  {10}^{6}  \: metres

A 200-pound man has a total foot imprint area of 72 in2. Determine the pressure this man exerts on the ground if (a) he stands o
masha68 [24]

Answer:

(a) Pressure will be 2.777pound/in^2

(B) Pressure will be 5.555pound/in^2

Explanation:

We have given weight of the body = 200 pound

Total area of foot imprint A=72in^2

(A) When man stands on both feet total area will be A=72in^2

So pressure P=\frac{weight}{area}=\frac{200}{72}=2.777pound/in^2

(B) When man stands on 1 foot

So area =\frac{72}{2}=36in^2

Pressure P=\frac{weight}{area}=\frac{200}{36}=5.555pound/in^2
