Atom's chemical properties are determined by the number of electrons in its outermost shells.
Based on the number of electrons in the shells, it decides the reactivity of atoms.
Atoms with same number of electrons in the outer shells have similar chemical properties.
If atoms have 1,2 or 3 valence electrons they react by giving out those electrons to become stable. If atoms have 6 or 7 electrons in the outer shell they react by taking in electrons to complete its outer shell.

How long will it take a person walking at 2.1 m/s to travel 13 m?
MrRissso [65]

Answer:

I gonna give you the number so but you need to round 6.19047619048

Explanation:

  • This is a speed formula so you would use the formula speed=distance/time
  • You need to rearrange it to time=distance/speed
  • So you need to divide 13m by 2.1 m/s

What is santa's average speed when visiting houses if he visits 800 million houses over 48 hours?
goldenfox [79]

Well, "speed" normally = (total distance covered) / (time to cover the distance).

In this case, we don't know the total distance that Santa has traveled, so the question can be answered only if we're willing to consider some other meaning of "speed".

Maybe we could say that in this case, "speed" means the average rate at which he visits houses. Then ...

Speed of visits = (total houses visited) / (time to visit them).

Speed of visits = (800 million houses) / (48 hours)

Speed of visits = 16.67 million houses per hour.

That's 277.8 thousand houses per minute

That's <em>4,630 houses per second</em>

A bowling ball traveling with constant speed hits pins at the end of a bowling lane 16.5m long. The bowler hears the sound of th
sweet-ann [11.9K]

Answer: The speed of the ball is 7.64 m/s.

Explanation:

The distance between the player and the pins is 16.5m

if the velocity of the ball is V, then the time in which the ball reaches the pins is:

T = 16.5/V

Now, after this point, the sound needs

T' = 16,5/340 = 0.049 seconds to reach the player, this means that the time in that the ball needs to reach te pins is:

2.65 s - 0.49s = 2.16s

Then we have:

T = 2.16s = 16.5/V

V = 16.5/2.16 m/s = 7.64 m/s

You collect some data on horse racing along a straight track. You are able to fit the motion of the horse to a function during t
Digiron [165]

Answer:

The equation is missing in the question. The equation is $10 m  + 5(m/s^2)t^2+3(m/s^3)t^3$

a). $v=10 t +9t^2$ , the horse will not turn.

b). a(t) = 10 + 18t

Explanation:

Given :

$x(t)=10 m  + 5(m/s^2)t^2+3(m/s^3)t^3$

∴ At t =0, x = 10 m

a). Velocity as a function of time

$v = \frac{dx}{dt} $

  = $10 t +9t^2$

Turning velocity must be zero.

v(t) = 0

$10 t +9t^2=0$

$\therefore t = 0 \text{ or}\ t =-\frac{10}{9}$

Taking the positive value of time.

The horse will not turn.

b). Acceleration as a function of time.

$a(t)=\frac{dv}{dt}$

     = 10 + 18t

∴ a(t) = 10 + 18t
