Answer:

1. They’re invisible - Radio waves

2. They have colors - Visible

3. They’re used to learn about dust and gas clouds. - Both

4. They can travel in a vacuum. - Both

5. They’re used to find the temperature of stars. - Visible

6. They have energy. - Both

Explanation:

The magnetic spectrum consists invisible and visible part of the spectrum. The invisible part consists of radio waves. These are waves used for radios, tvs, and cellphone communications. They satisfy all the properties of transverse waves.

The visible part comes from light. This is the part that is visible to the naked eye. Examples are ultraviolet rays, the sun, neon lights etc. To determine how hot something is, the visible portion is used. The brighter the object, the hotter it is.  Thus, the brightness of the stars can be determined by the color of the light emitted. The visible rays satisfy all the properties of transverse waves. However, light is considered a dual nature - it has wave and electron-like properties.

Anika asks Eva to roll a basketball and then a bowling
Alex73 [517]

Answer:

the bowling ball, because it has more mass and  therefore more inertia

Explanation:

As per law of inertia we know that if an object is having more inertia then it is difficult to change state of motion.

Inertia is the property of mass of an object which always resist to change the state of motion of the object.

If an object has more inertia then it is more difficult to change the state of motion.

Now we know that we have one bowling ball and one basket ball, since bowling ball is having more mass then it must have more inertia so it is difficult to start the motion in bowling ball.

So correct answer will be

the bowling ball, because it has more mass and  therefore more inertia
