(Note: In Problems, assume a number like 6.4 is accurate to ; and 950 is unless 950 is said to be “precisely” or “very nearly 950, in which case assume 950 )

Multiply 2.079 x 102 m by 0.082 x 10-1, taking into account significant figures.

Solution 9P STEP 1:- First let’s find the speeds for all the option given, i) A wind-up toy car that moves 0.15 m in 2.5 s, speed = distance / time = 0.15/2.5 = 0.06 m/s ii) A soccer ball that rolls 2.3 m in 0.55 s, speed = distance / time = 2.3/0.55 = 4.18 m/s iii) A bicycle that travels 0.60 m in 0.075 s. speed = distance / time = 0.60/0.075 = 8.26 m/s iv) A cat that runs 8.0 m in 2.0 s., speed = distance / time = 8.0/2.0 = 4 m/s...
