Answer:
Longitudinal and transverse waves have many similarities and differences.
Explanation:
Similarities:
Mechanical waves can be transverse and longitudinal waves.
Transverse and longitudinal waves both have wavelengths and frequencies.
They both have amplitudes
Both waves can travel through a medium or not, but it depends on whether is an electromagnetic or a mechanical wave.
Differences:
Electromagnetic waves can only be transverse.
The particles of the medium in a longitudinal wave move parallel to the direction (motion) of a wave. It is in this back and forth motion.
The particles of the medium in a transverse wave move perpendicular to the direction (motion) of a wave. This means that there would be right angles showing that they are perpendicular.
Longitudinal waves have rarefactions and compressions.
These rarefactions and compressions are used to measure the wavelength of a wave. For instance, a wavelength in a longitudinal wave is measured from rarefaction to rarefaction
Transverse waves have troughs and crests.
Amplitude in a transverse wave is measured from the midline to the crest of trough.
Amplitude in a longitudinal wave is measured based on how closely packed the particles of the medium are
I hope this helps
Answer:
The answer to your question is below.
Explanation:
Atoms are composed by three different subparticles
- protons are small particles positive charged located in the nucleus.
- neutrons are small particles without a charged located in the nucleus.
- electrons are the smallest subparticles and are negatively charged.
In a neutral atom, the amount of positive charges (protons) is equal to the amount of negative charges (electrons) so it does not have any charge.
If a neutral atom gains one or more electrons it would be negative.
Answer:
6 bricks
Explanation:
For the bricks system to NOT fall over, then the center of mass of the system must lie within the touching area of the bottom brick.
Let the reference line be at the left end of the base brick, and the bricks are being stacking to the right direction.
- The 1st brick would have a center of mass at 20/2 = 10 cm or 10 + 0, this is < 20 cm so it stays
- 2 stacked bricks would have a center of mass at (10 + 14)/2 = 12 cm or 10 + 2, this is also < 20 cm so it stays
- 3 stacked bricks would have a center of mass at (10 + 14 + 18) / 3 = 14 cm or 10 + 2*2, this is also < 20 cm so it stays
- 4 stacked bricks would have a center of mass at (10 + 14 + 18 + 22)/4 = 16 cm or 10 + 2*3, this is also < 20 cm so it stays
- 5 stacked bricks would have a center of mass at (10 + 14 + 18 + 22 + 26)/5 = 18 cm or 10 + 2*4, this is also < 20 cm so it stays
- 6 stacked bricks would have a center of mass at (10 + 14 + 18 + 22 + 26 + 28)/5 = 20 cm or 10 + 2*5, this is also <= 20 cm so it stays before tipping over.
- The 7th brick would make everything fall down.
Power plants release sulfur dioxide and nitrogen oxides into the atmosphere, where they combine with water vapor to form acid precipitation. The correct option among all the options that are given in the question is the first option or option "a". I hope the answer will help you and it is the one you were looking for.
