Answer:

The answer is below

Explanation:

(a) 1s22s22p63s23p5 it's a halogen, halogens are in group 7A in the periodic table, that means that that have 7 electrons in the outermost shell.

  outermost shell = 3   number of electrons = 2 + 5 = 7

(b) 1s22s22p63s23p63d74s2 it's an alkaline earth metal, these elements are in the 2A group and have 2 electrons in the outermost shell.

outermost shell 4 number of electrons = 2

(c) 1s22s22p63s23p63d104s24p6 This is an inert gas, these elements have 8 electrons in the outermost shell.

outermost shell 4 number of electrons = 2 + 6 = 8

(d) 1s22s22p63s23p64s1 This is a alkali metal, these elements have 1 electron in the outermost shell

outermost shell 4 number of electrons = 1

(e) 1s22s22p63s23p63d104s24p64d55s2  it's a transition metal. Besides this the outermost shell of this element is 5, shell 4 is incomplete, (4d5) letter d is for transition metal.

outermost shell 5, we consider 4  number of electrons (d) = 5

(f) 1s22s22p63s2  it's an alkaline earth metal, these elements are in the 2A group and have 2 electrons in the outermost shell.

outermost shell 3 number of electrons = 2

The parachute on a drag racing car deploys at the end of a run. If the car has a mass of 820 kg and the car is moving 36 m/s, wh
Lelechka [254]

In order to determine the required force to stop the car, proceed as follow:

Calculate the deceleration of the car, by using the following formula:

v^2=v^2_o-2ax

where,

v: final speed = 0m/s (the car stops)

vo: initial speed = 36m/s

x: distance traveled = 980m

a: deceleration of the car= ?

Solve the equation above for a, replace the values of the other parameters and simplify:

\begin{gathered} a=\frac{v^2_o-v^2}{2x} \\ a=\frac{(36\frac{m}{s})^2-(0\frac{m}{s})^2}{2(980m)}=0.66\frac{m}{s^2} \end{gathered}

Next, consider that the formula for the force is:

F=ma

where,

m: mass of the car = 820 kg

a: deceleration of the car = 0.66m/s^2

Replace the previous values and simplify:

F=(820kg)(0.66\frac{m}{s^2})=542.20N

Hence, the required force to stop the car is 542.20N
