Human reaction time is usually about 0.18 s. If your lab partner holds a ruler between your finger and thumb and releases it from rest without warning, how far can you expect the ruler to fall before you catch it? (a = -g = -9.81 m/s .) - 0.32 m ⊝ - 0.88 m ⊝ - 0.16 m ⊝ - 0.09 m ⊝ CLEAR ALL ❮ PREVIOUS

–0.16 m

Explanation:

From the question given above, the following data were obtained:

Time (t) = 0.18 s

Acceleration due to gravity (g) = –9.81 m/s²

Height (h) =?

We can obtain how far the ruler will fall by using the following equation:

H = ½gt²

H = ½ × –9.81 × 0.18²

H = ½ × –9.81 × 0.0324

H = –0.16 m

Thus, the ruler will fall –0.16 m before you will catch it.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
