1: copper is a good conductor
most metals tend to be good conductors because it is easy for electron currents to flow through them
Answer:
- Time delta is associated with difference in wavelengths
Explanation:
When pulsating radio waves consisting of different wavelengths pass through the ionized gas in interstellar space, the fast oscillating radio waves travel relatively faster than the slowly oscillating radio waves. As a result radio waves get dispersed and there is a time difference between the radio waves with different wavelength when the pulses arrive.
Answer:
A. 20 N down
Explanation:
It's asking how much force of gravity is acting on it. The book weighs 20 Newtons so that's how much gravity is being applied. Hope this helps
The sound comes from the speakers which produce sound waves which is the music, the volume could be changed producing a louder sound or a quieter sound which means that the speakers could produce more sound waves or less sound ways ( depends on the volume )
The correct matches are as follows:
<span>1. Mechanical Energy
</span>This is the energy of motion and position - Kinetic Energy and Potential Energy are included here.
<span>
2. Electrical Energy
</span>This is the type of energy that is given off as a result of electrons (charges!) moving through a conductor.
<span>
3. Light Energy
</span>This is the only form of energy we can see with our eyes!
<span>
4. Thermal Energy
</span>This is heat energy! It can be transferred through conduction, convection, or radiation.
<span>
5. Sound Energy
</span>This is energy that is transmitted through vibrations.
<span>
6. Kinetic Energy
</span>This is the energy that all moving objects have. <span>
7. Potential Energy
</span>This is stored energy, waiting to be used!
