In order to take a field trip to a science museum, ms speedi's students sold scented pencils for $1. in the classroom, rowena tried to put the $1 s into 2 equal piles and found one left over at the end. when polly tried putting the bills in 3 equal piles, she also ended up with one extra bill. frustrated, they tried 4, 5,and 6 equal piles and each time had $1 left over. finally rowena put all the bills evenly into 7 equal piles, and none were left over.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
