You told your insane friend that it will take the book 5.6 s to get to the ground.
From the question given above, the following data were obtained:
Height (H) = 155 m
<h3>Time (t) =? </h3><u>NOTE</u>: Acceleration due to gravity (g) = 10 m/s²
The time taken for the book to get to ground can be obtained as follow:
<h3>H = ½gt²</h3>155 = ½ × 10 × t²
155 = 5 × t²
<h3>Divide both side by 5</h3>t² = 31
<h3>Take the square root of both side </h3>Thus, the time taken for the book to get to the ground is 5.6 s
Hence, you told your insane friend that it will take the book 5.6 s to get to the ground.

The power dissipated by a resistor is equal to
where R is the value of the resistance and I is the current flowing through the resistor. From the formula, we can see that the larger R, the larger the dissipated power, so the greatest resistance dissipates more power.
