Q: If the amount of force of that is applied is increased, what happens to the work that a machine is producing? Read this paragraph and choose the correct option from the provided answers: Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. Contrary to popular belief, machines do not increase the amount of work that is done. They just change how the work is done. So if a machine increases the force applied, it must apply the force over a shorter distance. Similarly, if a machine increases the distance over which the force is applied, it must apply less force. Choices: - it's unchanged - it is harder - it's variable - it is easier A:
it is easier

Q: In frequency, the larger the air column, the larger the what? Read this paragraph and choose the correct option from the provided answers: a) The water forms the bottom of the tube and thus where the node of the wave will be. Thus the air column is where the sound wave can exist. The larger the air column, the larger the wavelength. Frequency is inversely proportional to wavelength, thus the tube with the smallest air column will have the highest frequency. So the answer is tube C. Choices: - mass - gravity - absorption - wavelength A:
wavelength

Q: Q: Unlike prokaryotes, eukaryotes have what? Read this paragraph and choose the correct option from the provided answers: Eukaryotes evolved about 2 billion years ago. Unlike prokaryotes, eukaryotes have a cell nucleus. They have more structures and are better organized. Organelles within a eukaryote can perform certain functions. Some supply energy; some break down wastes. Eukaryotes were better able to live and so became the dominant life form. Choices: - cell membrane - golgi apparatus - cell wall - cell nucleus A:
A: cell nucleus

Question: Q: How many types of bosons are there? Read this paragraph and choose the correct option from the provided answers: There are four known types of bosons, which are force-carrying particles. Each of these bosons carries a different fundamental force between interacting particles. In addition, there is a particle which may exist, called the "Higgs Boson", which gives objects the masses they have. Some types of bosons have mass; others are massless. Bosons have an electric charge of +1, -1, or 0. Choices: - three - one - five - four A:
Answer: four

Choices: - an alkali - a metalloid - a chloride - an amine A:
**Answer**
an amine

Q: When the wind deposits sand, it forms small hills, what are these hills called? Read this paragraph and choose the correct option from the provided answers: When the wind deposits sand, it forms small hills. These hills are called sand dunes ( Figure below ). For sand dunes to form, there must be plenty of sand and wind. Sand dunes are found mainly in deserts and on beaches. Choices: - sand tunnels - snow banks - mud puddles - sand dunes A:
(Answer)
sand dunes
