The graph shows the speed of the cart with three different fan speeds. which line represents the cart with the greatest acceleration? what is the fan speed for this cart? which line represents the cart with the least acceleration? what is the fan speed for this cart?

Which line represents the cart with the greatest acceleration?   C

What is the fan speed for this cart? High

Which line represents the cart with the least acceleration? A

What is the fan speed for this cart? Low

1) Which line represents the cart with the greatest acceleration?
The line that represents the cart with the greatest acceleration is the line corresponding to cart C (green line).
In fact, the acceleration is defined as the variation of speed per unit time:

and this corresponds to the slope of the line: the higher the slope, the larger the acceleration.

2) What is the fan speed for this cart?
It depends on the time at which we calculate it. For instance, if we take the point at t=5 s, we see that the fan speed is (green light) 160 cm/s.

3) Which line represents the cart with the least acceleration?
The line that represents the cart with the least acceleration is the blue line (cart A): as we said at point 1), the higher the slope, the larger the acceleration, so the cart with the least acceleration is the one with the smallest slope, which is the blue line.

4) What is the fan speed for this cart?
Again, it depends on which time we calculate the speed at. For instance, if we take again the point at t=5 s, we see that the speed of the fan is (blue line) 90 cm/s.

The given question is incomplete. The complete question is as follows.

On the basis of periodic trends, choose the larger atom from each pair (if possible): match the elements in the left column to the appropriate blanks in the sentences on the right. make certain each sentence is complete before submitting your answer.

          Sn, F, Ge, not predictable, Cr

Of Ge or Po, the larger atom is

Of F or Se, the larger atom is

Of Sn or I, the larger atom is

Of Cr or W, the larger atom is

Explanation:

When we move down a group then there occurs an increase in atomic size of the atoms due to increase in the number of electrons.

Ge is a group 14 element which lies in period 4 and Po is a group 16 element that lies in period 6. As polonium is larger in size as compared to germanium.

Fluorine is a group 17 element and lies in period 2. Selenium is a group 16 element lies in 4. Therefore, selenium is larger in size as compared to fluorine.

Sn is a group 14 element that lies in period 5 and I is a group 17 element that lies in period 5. Hence, I is a larger atom.

Cr is a d-block element which lies in period 4 and W is also a d-block element which lies in period 6. Hence, W is larger in size than Cr.

Thus, we can conclude that given blanks are matched as follows.

Of Ge or Po, the larger atom is Po.Of F or Se, the larger atom is Se.Of Sn or I, the larger atom is I.Of Cr or W, the larger atom is W.
