A body can have a constant speed yet a nonzero acceleration when it is in a circular motion because though it is having a constant speed but the direction in which it is moving keeps changing at each instance and since acceleration is a vector quantity,it becomes non-zero.
The first nonzero digit in a number is the number whose product is one. THINK ABOUT IT! resources:my brain, my notes, my math book DONT RELY ON THE COMPUTER WHO KNOWS IT MAY BE WRONG.
The greatest nonzero place is the number closest to the left (or the greatest number) that is not zero. So in this example, that would be the 8. So you would round the 8 up to a 9 (since 6 is greater than 4). So your answer would be 0.9
A number without a variable. Ex.) 5 is a constant, 5x is not.
