Front

How many grams of sulfuric acid are used in a reaction if the answer is 98 g?

Back

98 g of sulfuric acid were used in the reaction.

Front

What type of material is best for creating computer chips that partially conduct electricity?

Back

Metalloids are the best materials for creating computer chips that partially conduct electricity.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

How does potential energy change as an object moves down a hill?

Back

As an object moves down a hill, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between force and motion?

Back

An object will continue to move in the direction of the applied force, and its velocity will change based on the magnitude of the force.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, making them useful in semiconductors.
