Hello student, to solve the given questions, pressure can be given by row gh and also it is equal to force divided by area.
00:11
Now here for question number one, let us put the value in the first relation.
00:17
Pressure will be equal to.
00:19
Now density of mercury is given by 13 .6, multiply by 10x2 3 in kilogram per meter cube.
00:26
Multiply by g is 9 .8, then height is given, that is 0 .2 meters.
00:33
Now after this calculation, we find the final answer for question number one, that is, pressure will be equal to 2 .67 into 10 to power 4 pascals.
00:45
Now for the second question, again, we need to find the pressure.
00:50
So using the same relation, but for force per unit area, we get pressure equals.
00:54
Here force can be written as mg divided by area a.
00:58
Now using the values given in the statement we get mass is 1000 kilogram multiplied by g is 9 .8 divided by area is given 1 .25 meters square.
01:11
So after this calculation we get the final answer for pressure...
