What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It consists of a coil of wire, often wrapped around a core of ferromagnetic material.

How does the strength of an electromagnet depend on its components?

Back

The strength of an electromagnet depends on the amount of electric current flowing through the wire, the number of turns in the coil, and the type of core material used.

Front

Why is water known for having a high specific heat?

Back

Water has a high specific heat due to the hydrogen bonds between its molecules, which require more energy to break, allowing it to absorb more heat without a significant change in temperature.

Front

What is the purpose of a control group in an experiment?

Back

A control group is used as a baseline to compare against the experimental group, helping to isolate the effects of the variable being tested.

Front

What is the significance of measuring plant heights in an experiment?

Back

Measuring plant heights allows researchers to quantify growth and assess the effects of different treatments or conditions on plant development.

How do you calculate the average of a set of measurements?

Back

To calculate the average, sum all the measurements and then divide by the number of measurements.

Front

What is the average height of the plants measured at 10.6 cm, 10.8 cm, and 10.9 cm?

Back

The average height is 10.77 cm.
