Answer:
D)The Earth moves in an elliptical orbit around the sun
The statement earth moves in an elliptical orbit around the sun best describes the movement of earth around the sun.
What is earth?Earth is the third planet of the solar system and the only astronomical object known to support life.
What is an elliptical orbit?When an object moves around another object in an oval shaped path, it is known to be revolving in an elliptical orbit.The orbit is elliptical because of Newton's law of gravity.The planets in the solar system orbit the sun in elliptical orbits. Many satellites orbit the Earth in elliptical orbits as does the moon.The movement of the earth around the sun in a fixed path or orbit is called Revolution. The axis of the earth which is an imaginary line, makes an angle of 66½° with its orbital plane.
Hence, option D is the correct answer.

What is the purpose of a catalyst?
Answer:
option c
Explanation:
as catalyst increases the reaction while activation energy is inversely proportional to rate of reaction, so option c is correct
The purpose of a catalyst to lower the activation energy of a reaction.
What is catalyst?A type of chemical that, without becoming consumed by the process, speeding a chemical reaction or reduce the temperature as well as the pressure required to initiate one. The addition of a catalyst to speed up a reaction is known as catalysis.
What is activation energy?The bare minimum additional energy needed by a reactive molecule to transform into a product is considered as activation energy.
The purpose of a catalyst is to lower the activation energy of a reaction.
Therefore, the correct answer will be an option (C).

Calculate the vapor pressure (in torr) of a 35°C solution of ethanol and propanol where the mole fraction of propanol is .75. Assume Ideal behavior P°ethanol35=100torr P°propanol35=36torr
The vapor pressure (in torr) of a 35°C solution : 52 torr
Further explanationGiven
x propanol = 0.75
P°ethanol=100 torr
P°propanol=36 torr
Required
the vapor pressure
Solution
Raoult's Law
P solution = xA.P°A +xB.P°B
x ethanol = 1- 0.75 = 0.25
Input the value :
P solution = 0.25 x 100 + 0.75 x 36
P solution = 25 + 27
P solution = 52 torr

Describe an every day example of an object that has energy of motion and object that has stored energy
Answer:
Humans
Explanation:
Humans have energy of motion and store energy.
Every object will have any form of energy. For instance, when we are walking we gains a kinetic energy. We use electronic devices where electrical energy is stored and can be converted to mechanical energy to activate any motors.
What is energy transformation?Energy can neither be created nor be destroyed. However it can be transformed to any other forms. Thus, the total energy will conserved always.
We have a lot of example for energy transformation and storage. The energy form stored by virtue of the position of an object is called potential energy. Whereas, when the object starts moving potential energy converts to kinetic energy.
Thus, thermal vibrations of particles, our every day activities all are associated with a kinetic energy. Kinetic energy of each body depends on the mass and velocity of the body. The more the mass and velocity more will be the kinetic energy.
