If air resistance can be neglected, how does the acceleration of a ball that has been tossed straight upward compare with its ac
timama [110]
They are the same. If this is all happening on Earth, then the ball's acceleration is 9.8 m/s^2 in either case. That's the acceleration of gravity around here.

All of the alkali metals, Group 1, have one valence electron. Which of these would represent the oxidation number of the alkali
melamori03 [73]
The elements found in the Group 1, or the Alkali Metal Group, have electronic configurations that end in s^{1}.This means that they have 1 electron readily available to release in order to achieve a stable state. 

When these atoms release the valence electron, they will achieve a stable state. For example, Lithium's stable state will be Li^{+} and Sodium will be Na^{+}. 

The oxidation state will then be +1. 

The answer is C.

A cyclist acceleration from 0m/s to 8m/s in 3second. what is his acceleration?​
umka2103 [35]

Answer:

2.66 m/s² .

Explanation:

Initial velocity , u = 0 m/s

Final Velocity , v = 8 m/s

Time Taken , t = 3 s

So , Acceleration = (v-u)/t = (8 m/s - 0 m/s) /3 sec . = 8/3 m/s² = 2.66 m/s²
