Question

force f=(20+/-1) n is applied perpendicular on the surface having area A=(8+/-2) calculate the percentage error in the pressure on the surface ​

Answer 1

Answer:

P=F/A

Then put the values

20/-1/8/-2

Then they will be multiplied by resiprokal

Then then equation will be

20/-1*-2/8

So 8 will be cut by 20 and you will get 5 and 2

Both the - with 1 and 2 will also be cut

The result will be 10/2 which will be cut the final answer will be 5pa

Explanation:this is all
