Two objects of the same mass are moving at the same velocity. You give
vladimir1956 [14]
I would imagine they’d be equal.
F = ma
We can treat mass and force as constants because they do not change throughout both systems and they are the same on both systems. That would mean the acceleration would be the same for both systems.

An explanation of this could be the two forces are acting in different directions, so one is positively accelerating the object and the other is negatively accelerating it

Confirm the answer pllzzzzzz
Studentka2010 [4]

Explanation:

In chemistry, a chemical formula is a scientific notation to show the chemical proportion of atoms that represents a particular compound or molecule. The empirical formula of a chemical compound illustrates the simplest whole number ratio between the elements contained in the compound whereas the molecular formula is the representation of the actual whole number ratio between each element of the compound.

Given that the empirical formula of carbamide is \text{CH}_{4}\text{N}_{2}\text{O}, then, the corresponding molecular weight (M_{r}) is

                                 M_{r} \ = \ 12 \ + \ 4(1.008) \ + \ 2(14) \ + \ 16 \\ \\ M_{r} \ = \ 60.032 \ \text{g mol}^{-1}.

Subsequently, using the relation

                      n \ \times \[M}_{r}(\text{empirical formula})] \ = \ M_{r}(\text{molecular formula}),

where n is the multiple of empirical formula unit.

Therefore,

                                             n \ = \ \displaystyle\frac{M_{r}(\text{molecular formula})}{{M}_{r}(\text{empirical formula})} \\ \\ n \ = \ \displaystyle\frac{60 \ \text{g mol}^{-1}}{60.032 \ \text{g mol}^{-1}} \\ \\ n \ = \ 1

Water, H2O, frequently forms Hydrogen Bonds with other non metal atoms.
slamgirl [31]

Answer:

Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.

Explain functional group containing carbon hydrogen and oxygen
solong [7]

Answer:

Any organic compound with a carboxyl functional group—a carbon with one double bond to an oxygen and a single bond to another oxygen, which is then connected to a hydrogen—is referred to as a carboxylic acid.
