what is Newton's second law of motion
Answer:
Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
Explanation:
Answer:
F= m x a
force = mass x acceleration
Explanation:
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased.

Ozone has a molecular formula of O3. If 7.92*1024 atoms of oxygen react to form ozone, then 337.92 moles of ozone will produce.
What is molecular formula?Molecular formula is defined as an expression that defines a number of atoms of each element in one molecule of a compound.
It can also be defined as a chemical formula that gives the total number of atoms of each elements in each molecules of a substance.
Ozone is defined as a highly reactive gas composed of three oxygen atoms and form a layer above the earth surface called as ozone layer.
1 oxygen atom = 8 g
1 mole of ozone = 8 x 3 = 24 g
7.92 x 10²⁴ = 8110.08 g
24 g = 1 mole
So, 8110.08 g = 337.92 moles
Thus, Ozone has a molecular formula of O3. If 7.92*1024 atoms of oxygen react to form ozone, then 337.92 moles of ozone will produce.

What are some other type of chemical reactions? What makes them different?
3. Calculate the mass of NH3 that can be produced from the reaction of 125 g of NCI:
according to the following equation:
NCl3 + 3 H2O → NH3 + 3 HOCI
The mass of NH₃ : = 17.629 g
Further explanation
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Given
125 g NCl₃
Required
The mass of NH₃
Solution
mol NCl₃(molar mass : : 120.5 g/mol)
= 125 g : 120.5 g/mol
= 1.037
From the equation, mol ratio NCl₃ : NH₃ = 1 : 1, so mol NH₃ = 1.037
Mass NH₃(molar mass : 17 g/mol) :
= 1.037 x 17
= 17.629 g

2KOH --> K²O + H²O
Explanation:
Potassium Hydroxide = KOH
Potassium oxide = K²O
Water = H²O
KOH --> K²O + H²O
K = 1. K = 2.
2KOH --> K²O + H²O
O = 2. O = 2.
H = 2. H = 2.
Balanced symbol = 2KOH --> K²O + H²O
Balanced word = 2Potassium Hydroxide --> Potassium oxide + Water.

Solid Snake is being chased up the communications tower. Solid Snake is 75 kg and is carrying 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, how much work was done against gravity?
a.
4.04 kJ
b.
109.15 kJ
c.
135.34 kJ
d.
5.01 kJ
Solid Snake (75 kg) carries 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, the work done against gravity is 135.34 kJ (c).
What is work?In physics, work is the energy transferred to or from an object via the application of force along a displacement.
In this problem, the force that does the work is the one that opposes the weight.
Step 1: Calculate the total weight of the system.Solid Snake is 75 kg and is carrying 18 kg of equipment. The total mass is:
m = 75 kg + 18 kg = 93 kg
We can calculate the weight using Newton's second law of motion.
F = m . g = 93 kg . 9.8 m/s² = 911.4 N
Step 2: Calculate the total displacement.Solid Snake climbs 27 flights of stairs, each 5.5 m in height.
27 . 5.5 m = 148.5 m
Step 3: Calculate the work done.We will use the definition of work.
w = F . s = (911.4 N) . (148.5 m) . (1 kJ/1000 J) = 135.34 kJ
Solid Snake (75 kg) carries 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, the work done against gravity is 135.34 kJ (c).

There are two varieties in a population of squirrels: short tails and long tails. Long-tailed squirrels are better at jumping and balancing in trees. Scientists observe that over the span of 100 years, the proportion of the population with long tails increases from 10% to 60%. Which statement is most likely? (1 point)
The proportion of long-tailed squirrels may have increased due to a decrease in trees.
The proportion of short-tailed squirrels may have decreased due to an increase in trees.
The proportion of short-tailed squirrels may have decreased due to decreased food availability.
The proportion of long-tailed squirrels may have increased due to increased food availability.
The proportion of long-tailed squirrels may have increased due to increased food availability.
The statement has it that the percentage of long tailed increased also that the long tailed are better at jumping and balancing on trees.
The first option could is tempting but saying decrease in trees would not likely support the argument.
The last option has more sound options as more food availability may lead to population increment
