Question

A body is moving with speed (10.00 + 0.01) m/s.
The distance covered in time (5.00 + 0.01) s is
(1) (50.0 +0.3%) m (2) (2.00 +0.3%) m
(3) (20.0 + 0.3%) m (4) (50.0 + 2%) m​

Answer 1

I HOPE IT WILL HELPS YOU.

Answer 2

Answer:

Option 1

Explanation:

Here the figures are given in absolute values as well as their errors with these values.

The formula for speed is ;

Speed = Distance / time

According to given values;

Distance = Speed x time = 10 x 5 = 50 m

To take account for the errors;

Net error = 0.01 / 10 + 0.01/ 5

Net error = 0.01+0.02/10

Net error = 0.003 or 0.3 %

Hence the correct answer is option A

Distance (50.0 +0.3%)
