Answer:
3m/s²
Explanation:
Force applied to an object can be calculated thus;
F = ma
Where;
F = force applied (Newtons)
m = mass of substance (kg)
a = acceleration (m/s²)
According to the information provided in this question, F = 12.0 newtons, m = 4.0 kg, a = ?
Derived from F = m.a
We have; a = F/m
a = 12/4
a = 3
The resultant acceleration of the object is 3m/s².
Answer:
Does liquid HF conduct electricity?
Explanation:
HF is the precursor to elemental fluorine, F2, by electrolysis of a solution of HF and potassium bifluoride. The potassium bifluoride is needed because anhydrous HF does not conduct electricity.
Answer: OA is a balanced equation.
Explanation: For an equation to be balanced, the number of atoms and the total charge of each element in the reaction, of the product and reactant side must be the same.
Considering OA; 6 atoms of nitrogen is present in the reactant side. Shifting to the product side, 6 atoms of nitrogen is also present. Taking the other element in the reaction into account, the number of atoms of each element balances on both sides.
Milk (lowest acidity) < Coffee < Orange juice < Soda pops < vomit < Battery acid (highest acidity)
explanation :
pH values of all :
battery acid pH = 1.0
vomit pH = 2.0
soda pop pH = 2.5
orange juice pH = 3.5
coffee pH = 5.0
milik pH = 6.5
pH value is lesser acidity is more . high pH indicate lesser acidic nature
<span>blood is neither acid nor base
it is neutral
it has pH= 7.4</span>
