Honors Science Exam 1st Sem. 24 25

Front

What is the relationship between mass and inertia?

Back

Inertia is the resistance of an object to change its state of motion. The greater the mass of an object, the greater its inertia.

Front

How can you increase the strength of an electromagnet?

Back

You can increase the strength of an electromagnet by increasing the number of loops of wire around the core (nail) or increasing the current flowing through the wire.

Front

What happens to wavelength as you move from radio waves to gamma rays in the electromagnetic spectrum?

Back

Wavelength decreases as you move from radio waves to gamma rays.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable. In Ethan's experiment, it is the amount of salt added to the ice.

Front

What is resultant force?

Back

Resultant force is the overall force acting on an object when all the individual forces acting on it are combined.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is the effect of adding salt to ice?

Back

Adding salt lowers the freezing point of water, causing the ice to melt faster.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the significance of the number of loops in a wire coil for an electromagnet?

Back

The number of loops in a wire coil increases the magnetic field strength of the electromagnet.
