2. A cart travels continuously around a circular track with a constant acceleration. The track has a length of 10km.
At a specific time, t = 0, its position is measured.
It takes half an hour for the cart to complete one full lap of the track.
It takes two hours (from time t = 0) for the cart to complete ten full laps of the track.
The following formula describes this situation
at2
s=uot+
2
where
s is the displacement, measured in km
• u, is the velocity of the cart when t = 0, measured in kmh-2
t is the time taken, measured in hours
a is the acceleration of the cart, measured in kmh-2
a) Use the information about the position of the cart after half an hour to
write a formula linking u, and a.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !
