Answer to Problem 6.34QP

Solution

The pressure exerted by the gold block when it is on a square face is 3.8×103Pa_ .

Explanation of Solution

Explanation

Given

The given mass of block is 38.6g .

The given side of the square is 1.00cm .

Acceleration caused by gravitational force is 9.8m/s2 .

Conversion of 1g into kg is done as,

1g=11000kg

Therefore, conversion of 38.6g into kg is,

38.6g=1×38.61000kg=0.0386kg

The formula to calculate force is,

F=ma

Where,

  • F represents the force.
  • m represents the mass.
  • a represents the acceleration.

Substitute the value of mass and acceleration in above formula.

F=0.0386kg×9.8m/s2F=0.37828kgm/s2

Conversion of 1cm into m is done as,

1cm=1100m

Therefore, conversion of 1.00cm into m is,

1.00cm=1×1.00100m1.00cm=0.01m

The formula to calculate area of square is,

A=side2

Substitute the value of side in the above formula.

A=(0.01m)2A=1×104m2

The formula to calculate pressure is,

P=FA

Where,

  • P represents the pressure.
  • F represents the force.
  • A represents the surface area.

Substitute the value of force and area in above formula.

P=0.37828kgm/s21×104m2P=3.8×103kg/ms2

Conversion of 1kg/ms2 into Pa is done as,

1kg/ms2=1Pa

Therefore, conversion of 3.8×103kg/ms2 into Pa is,

3.8×103kg/ms2=3.8×103Pa

Therefore, the value of pressure exerted by the gold block when it is on square is 3.8×103Pa_

Answer to Problem 6.34QP

Solution

The pressure exerted by the gold block when it is on a rectangular face is 189.14Pa_ .

Explanation of Solution

Explanation

Given

The given mass of block is 38.6g .

The given side of the rectangular is,

Length=2.00cmBreadth=1.00cmHeight=1.00cm

Acceleration caused by gravitational force is 9.8m/s2 .

Conversion of 1g into kg is done as,

1g=11000kg

Therefore, conversion of 38.6g into kg is,

38.6g=1×38.61000kg=0.0386kg

The formula to calculate force is,

F=ma

Where,

  • F represents the force.
  • m represents the mass.
  • a represents the acceleration.

Substitute the value of mass and acceleration in above formula.

F=0.0386kg×9.8m/s2F=0.37828kgm/s2

Conversion of 1cm into m is done as,

1cm=1100m

Therefore, conversion of 1.00cm and 2.00cm into m is,

1.00cm=1×1.00100m1.00cm=0.01m2.00cm=0.02m

The formula to calculate area of rectangular face is,

A=Length×Breadth

Substitute the value of side in the above formula.

A=(0.01m)×(0.01m)A=2.00×104m2

The formula to calculate pressure is,

P=FA

Where,

  • P represents the pressure.
  • F represents the force.
  • A represents the surface area.

Substitute the value of force and area in above formula.

P=0.37828kgm/s22.00×104m2P=1891.4kg/ms2

Conversion of 1kg/ms2 into Pa is done as,

1kg/ms2=1Pa

Therefore, conversion of 1891.4kg/ms2 into Pa is,

1891.4kg/ms2=189.14Pa

Therefore, the value of pressure exerted by the rectangular face of block is 189.14Pa_

Conclusion

The pressure exerted by the gold block when it is on a square face is 3.8×103Pa_ .

The pressure exerted by the gold block when it is on a rectangular face is 189.14Pa_
