A subatomic particle found in the nucleus of an atom. It carries no electric charge. This desribes which of the following?
electron |
|
neutron |
|
atom |
|
proton |
A neutron is a subatomic particle found in the nucleus of an atom. It is neutral as it carries no electric charge.
Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 m/s2 to a mass of 1 kg |
|
1 m/s to a mass of 1 kg |
|
1 mph to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
An asteroid belt holds many of the asteroids in our solar system. It is located between the orbits of which planets?
Jupiter and Saturn |
|
Mercury and Venus |
|
Mars and Jupiter |
|
Mars and Earth |
The solar system also contains over a million rocky fragments of at least 1km in diameter called asteroids as well as millions more with smaller diameters. Many of these asteroids are an asteroid belt between the orbits of Mars and Jupiter.

0K |
|
-273°C |
|
32°F |
|
absolute zero |
Absolute zero is the coldest possible temperature in the universe. In the Kelvin scale, absolute zero is 0K and in the Celsius scale it is -273°C.
Which of the following is the correct order for types of radiation from longest to shortest wavelength?
microwaves → radio waves → visible light |
|
radio waves → visible light → gamma rays |
|
infrared waves → microwaves → ultraviolet light |
|
visible light → ultraviolet light → radio waves |
The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation. From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
