can a magnet attract a pure substance?

Answers

Answer:

Mike rides his bike 30 km in 150 minutes. What is his average speed in kilometers per hour?

Answers

Speed is distance divided by time. Simply put, if you drove 60 kilometres for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h. Let's take a more complex example: what's the average speed if you covered 425.5km in 5 hours 22 minutes and 30 seconds?
Mike average speed is 5 kilometers per hour, uhh i hope so

Please help quick! 3 questions if you answer all I will give brainliest

1. Identify at least two tools scientists use to study stars and galaxies, then explain how the tools you chose assist scientists in their work.

2. Name at least three properties of stars revealed by spectral characteristics

3. In 3-5 sentences, explain how a star is formed.

Answers

Answer:  1.Spectroscopes breaks the light from a single material into its component colors the way a prism splits white light into a rainbow. It records this spectrum, which allows scientists to analyze the light and discover properties of the material interacting with it.  

2.Optical Telescopes The now-indispensable optical telescope instrument was pioneered by Galileo Galilei in 1609, although others had created similar tools by then

2.A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.

3.Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.Once the pressure and the temperature inside get high enough for nuclear fusion to ignite, it creates a star.

Answer: Energy

Explanation:   The ability to do work or cause change is called energy. Energy comes from many sources, and is found in two main forms. One form, potential energy, is energy that has the potential, in an object at rest, to do work later. An example of this would be a car parked at the top of a hill with its brakes on.
