Answer:
about -1.26 m/s²
Explanation:
The acceleration can be found from the formula ...
a = (v2² -v1²)/(2d)
Here, we have the initial velocity v1=23 m/s, the final velocity v2=0, and teh distance d=210 m. Using the formula, we find the acceleration to be ...
a = (0 -23²)/2(210) ≈ -1.2595 . . . m/s²
The weight of the mouse in the SI unit would be 0.02 kg.
Mass is the unit which describe the quantity of matter in an object, the SI unit of mass is kilogram.
And conversion factor of one pound to one kg is
1 lb=0.4535 kg
Now the mass of the mouse in Si unit is calculated as
m=0.4535*4.41*10^(-2)
=0.02 kg
Therefore the mass of the mouse in the SI unit is 0.02 kg.
Answer:
Image result for In covalent bonds what is being shared
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
