Question

Write the following Name Experiments Observation Least count the ruler TO MEASURE THE LENGTH. BREADTH AND HEIGHT OF THE RECTANGULAR BLOCK MEAN LENGTH MEAN BREADTH MEAN HEIGHT BREADTH SR LENGTH HEIGH incm​

Answer 1

Answer:

Being that it takes the weight of an object on earth and converts it to Martian weight, the formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2. To find the Martian weight, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2

Answer 2

Answer:

Given that,

Length of the block l=(5.12+0.01)cm

Breadth of the block b=(10.15+0.01) cm

Thickness of the block t=(5.28+0.01) cm

We know that,

×100=0.48

%ΔV=0.48%

Hence, the percentage error in volume is 0.48.
