Prior to determining the experimental design, a scientist typically forms a hypothesis. The answer is letter B. this is to prepare the scientist, the possible outcome of their research before the experimental design whether they are wrong or not.
c. Money serves as a store of value.
b. Money is a unit of account.
d. all of the above
Answer;
A. Money is a medium of exchange.
Explanation;
Money actually serves several different key functions in our economy. It is a medium of exchange, a unit of account, and a store of value.
D. All of the above statements are true. Money is a medium of exchange, a unit of account, and a store of value.
Money is a medium of exchange because it is used to buy goods and services. It is also a unit of account because prices and values are expressed in terms of money. Lastly, money serves as a store of value, allowing individuals to save and accumulate wealth over time. Money serves various essential functions in modern economies. It is a medium of exchange, facilitating the buying and selling of goods and services.
Money also acts as a unit of account, providing a common measure of value for comparing prices. Additionally, it serves as a store of value, allowing individuals to save and transfer purchasing power over time. Money enables economic efficiency, trade, investment, and financial transactions, making it a cornerstone of economic systems.

Answer:
The acceleration of the box is 2.
Explanation:
According to Newton's second law of motion, the acceleration of any object will be directly proportional to the net unbalanced force acting on the object and inversely proportional to the mass of the object.
Net force = Mass × Acceleration
So
Since in this case, the box is experiencing a force from east of magnitude 27 N and resisting force of about 17 N from west. So the net force will be the difference of acting and reacting force.
Net force = 27-17 = 10 N.
Thus,
So 2 is the acceleration of the box. Thus the magnitude of acceleration of the box is 2.
Answer:
350 Degrees Fahrenheit
Explanation:
Answer:
Magnitude of potential energy is increased by factor "2"
Explanation:
As we know that if two charge particles are placed at some distance "r" from each other then the electrostatic potential energy between two charge particles is given as
now we know that if the charge of one of the charge particle is increased to twice of initial charge then
now we can say from above two equations that
so on increase one of the charge to twice of initial value then the potential energy will become TWICE
