Answer: Option (C) is the correct answer.

Explanation:

Elements in a periodic table are arranged according to the increase in atomic number.

So, when we move from left to right in a periodic table then there occurs an increase in atomic number because there occurs an increase in the number of electrons of the atoms.

And, in neutral atoms the number of electrons and number of protons are the same.

Therefore, we can conclude that modern periodic table organized by increasing atomic number as one goes across a row from left to right.

Determine the stopping distances for a car with an initial speed of 88 km/h and human reaction time of 2.0 s for the following a
seropon [69]

Explanation:

Given that,

Initial speed of the car, u = 88 km/h = 24.44 m/s

Reaction time, t = 2 s

Distance covered during this time, d=24.44\times 2=48.88\ m

(a) Acceleration, a=-4\ m/s^2

We need to find the stopping distance, v = 0. It can be calculated using the third equation of motion as :

s=\dfrac{v^2-u^2}{2a}

s=\dfrac{-(24.44)^2}{2\times -4}

s = 74.66 meters

s = 74.66 + 48.88 = 123.54 meters

(b) Acceleration, a=-8\ m/s^2

s=\dfrac{v^2-u^2}{2a}

s=\dfrac{-(24.44)^2}{2\times -8}

s = 37.33 meters

s = 37.33 + 48.88 = 86.21 meters

Hence, this is the required solution.
