[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]
ρ = density
m = mass
v = volume
Given
volume of olive oil = V=750 ml

The kinetic energy of an object can be determined using the equation , where is the kinetic energy, is the mass, and is the speed of the object. What is the mass of an object moving at a speed of 12 that has 36 J of kinetic energy?
Answer:
0.5kg
Explanation:
Given parameters:
Speed of the object = 12m/s
Kinetic energy = 36J
Unknown:
Mass of the object = ?
Solution:
Kinetic energy is the energy due to the motion of a body. It is mathematically expressed as;
K.E = [tex]\frac{1}{2}[/tex] m v²
Insert the parameters and solve;
36 = [tex]\frac{1}{2}[/tex] x m x 12²
36 = 72m
m = 0.5kg

The process of fermentation involves chemical reactions that convert solid glucose (C6H12O6) into aqueous ethanol and carbon dioxide gas. Suggest how the speed of reaction alters as the temperature changes from 60C to 30C.
Explanation:
The glucose molecules changes as following:
C6H12O6 —> C2H5OH + CO2
There are 12 atoms of H on the left side and 6 atoms of the right side. It can be balance by putting 2 in front of C2H5OH as shown below:
C6H12O6 —> 2C2H5OH + CO2
There are 6 atoms of C on the left side and 5 atoms on the right side. It can be balance by putting 2 in front of CO2 as shown below:
C6H12O6 —> 2C2H5OH + 2CO2

Contrast exo. and endothermic reactions and give an example for each?
Answer:
Explanation:
Endothermic reactions:
The type of reactions in which energy is absorbed are called endothermic reactions.
In this type of reaction energy needed to break the bond are higher than the energy released during bond formation.
For example:
C + H₂O → CO + H₂
ΔH = +131 kj/mol
it can be written as,
C + H₂O + 131 kj/mol → CO + H₂
Exothermic reaction:
The type of reactions in which energy is released are called exothermic reactions.
In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.
For example:
Chemical equation:
C + O₂ → CO₂
ΔH = -393 Kj/mol
it can be written as,
C + O₂ → CO₂ + 393 Kj/mol
Which statement best explains why protons are used
to identify an element?
Answer:
Every atom of an element will have the same number of protons
Explanation:
Protons are used to identify an element because every atom of an element will have the same number of protons.
Protons are the positively charged particles found in an atom. They are called the atomic numberEvery atom of an element has the same number of protons. An element can have different atom in form of isotopes. These isotopes are only identifiable by the number of protons they have.According to Newton's Second Law of Motion, if the force acting on ar
object stays the same, but the mass of an object increases, then

Morant Bay is 33 km south of Port Antonio a pigeon can fly at a speed of 1.2 m s what is the displacement of morant bay from Port Antonio
Answer:
33km due south
Explanation:
Morant Bay is 33km south of Port Antonio;
Problem: displacement of Morant bay from Port Antonio;
Displacement is a vector quantity. It is the length of path between two position and the direction inclusive.
So, it has magnitude and must be specified with a direction.
Therefore, the displacement of Morant Bay from Port Antonio is 33km due south.According to Periodic Law, elements arranged in order of increasing atomic number are placed together in groups having

Lets say a giant radioactive monster is attacking
Phoenix. This monster is so radioactive and big the air in
Feels easily over 120°. Is this an endothermic or
exothermic reaction?
Answer: exothermic reaction
The monster is releasing heat energy to the environment surrounding it. The term "exo" means "outside".
In contrast, an endothermic reaction is one where energy is absorbed from the environment to cool down the surrounding air.

Which of the following definitions best describes a parallel of latitude?
a--A line that is drawn horizontally around the earth and is parallel to the Prime Meridian.
b---A line that is drawn vertically down the earth and is parallel to the equator.
c--A line that is drawn vertically down the earth and is parallel to the Prime Meridian.
d--A line that is drawn horizontally around the earth and is parallel to the equator.
The statement that express the definitions of parallel of latitude as regards this question is :A: A line that is drawn horizontally around the earth and is parallel to the Prime Meridian.
A circle of latitude can be regarded as a line of latitude that found on Earth, it can be explained as abstract (east–west) small circle which connect all locations around Earth and this is been done at a particular latitude coordinate line.It is drawn horizontally and usually parallel to Prime Meridian.Therefore, option A is correct.

Explain your observations on what organisms need to grow. Explain how human activity can impact an organism's ability to obtain the resources it needs to survive. State your opinion about how human activity can be changed to have less impact on the lives of other organisms.
Answer:
The human being sometimes exploits the resources that other living organisms need to survive. This is how competition for the environment increases and many species on this planet are at risk of extinction.
Explanation:
An example of this is how humans exploit mambu canes for commercial products, such as sweets and even toys, thus generating that the panda bear species does not have a food resource to survive.
