Answer:
Option B
0.3 m/s2 South
Explanation:
Acceleration,
where v and u are final and initial velocities respectively, t is the time taken
Substituting 14.1 m/s for v, 17.7 m/s for u and 12 s for t then

Since this is negative acceleration, it's direction is opposite hence 0.3 m/s2 South
Answer:
it's option 2 : the medium increases in temperature while remaining in the same phase
Answer:
0.015%
Explanation:
Data provided in the question:
Length by which the measuring tape can be off, δL = 0.42 cm
Total measured length for which Error of δL is observed, L = 28 m
Now,
we know,
1 m = 100 cm
Thus,
28 m = 28 × 100 = 2800 cm
Percent uncertainty = [δL ÷ L] × 100%
= [0.42 ÷ 2800] × 100%
= 0.015%
