2/3
What layer of the Earth is directly beneath the crust?
The mantle
What is the primary function of a web browser?
A web browser is used to access and view websites on the internet.
What is the primary focus of mechanical engineering?
The primary focus of mechanical engineering is the design, analysis, manufacturing, and maintenance of mechanical systems.
What is an "alloy" in the context of materials engineering?
An alloy is a mixture of two or more metals, or a metal and another element, designed to have specific properties.
If a recipe requires 3 cups of flour for every 2 cups of sugar, how much flour is needed if you have 8 cups of sugar?
12 cups
What is the formula for calculating the speed of an object?
Speed = Distance / Time
What is an operating system, and can you name two examples?
An operating system (OS) is software that manages computer hardware and software resources and provides common services for computer programs. Examples include Windows and macOS.
Name one common device that an electrical engineer might work on.
Electrical engineers might work on devices such as smartphones, computers, or electrical circuits.
Define "tensile strength" and why it is important in engineering.
Tensile strength is the maximum amount of tensile (pulling) stress that a material can withstand before breaking. It is important because it determines how much load a material can handle when being stretched.
Solve for X: 3x-5=16
x=7
What is the chemical formula for water, and what do the letters represent?
H2O; H represents hydrogen and O represents oxygen. There are two hydrogen atoms and one oxygen atom in a molecule of water.
What is a programming language, and can you name three popular ones?
A programming language is a formal language comprising a set of instructions that produce various kinds of output. Three popular programming languages are Python, Java, and JavaScript.
What is a common application of chemical engineering in everyday life?
A common application of chemical engineering is the production of household chemicals, such as detergents and soaps, or the development of pharmaceuticals.
What does the term "kinematics" refer to in mechanical engineering?
Kinematics is the branch of mechanics that studies the motion of objects without considering the forces that cause the motion.
A right triangle has one leg that measures 6 cm and a hypotenuse that measures 10 cm. What is the length of the other leg?
b=8 cm
Explain the greenhouse effect and how it contributes to global warming.
The greenhouse effect is the process by which certain gases (such as carbon dioxide, methane, and water vapor) in the Earth's atmosphere trap heat from the sun. These gases allow sunlight to enter the atmosphere and reach the Earth's surface, but they prevent some of the heat from escaping back into space. This trapped heat warms the Earth's surface and contributes to global warming, leading to changes in climate patterns.
Explain the concept of encryption and why it is important for online security.
Encryption is the process of converting information or data into a code, especially to prevent unauthorized access. It is important for online security because it protects sensitive information (such as passwords, credit card numbers, and personal data) from being accessed by hackers and cybercriminals. By encrypting data, only authorized parties with the correct decryption key can read the information.
Explain how biomedical engineering contributes to healthcare.
Biomedical engineering contributes to healthcare by combining principles of engineering with biological sciences to create technologies and devices that improve medical care. This includes the development of medical equipment, prosthetics, diagnostic machines, and artificial organs. Biomedical engineers also work on improving medical procedures and treatment methods to enhance patient outcomes.
Explain the difference between "AC" (alternating current) and "DC" (direct current) in electrical engineering.
AC (alternating current) is an electric current that reverses direction periodically, while DC (direct current) is an electric current that flows in one direction only. AC is commonly used in power supply systems for homes and businesses, while DC is often used in batteries and electronic devices.
