How would the absence of gravity affect the formation of planets
Cerrena [4.2K]

Answer:

The rocks and debris would never accrete into a planet.

Explanation:

Gravity is an attraction force and dependents on the mass of the objects but in the absence of the force, the rocks and debris would not come together to form a clump. So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet. So,  we can say that in the absence of gravity, the rock and debris would never accrete into a planet.

The electrons of photosystem I A. attach to water molecules during the light reaction. B. produce molecules of oxygen that enter
Sergeeva-Olga [200]

Answer:d.are eventually replaced by electrons from photosytem 11

Explanation:there are two photosystems in the photosynthetic process.PSI and PS II. PS I has a reaction center called P700 because it's chlorophyll has a maximum absorption of 700nm wavelength.PSII has a reaction center called P680nm for similar reason.when an excited electron is transferred to P700,it becomes excited.this electron is passed down from from acceptor to another, until it is used to reduce NADP+ to NADPH.this electron is replaced when P680 gets excited by a photo of light and splits water to release electrons , protons and Oxygen

** ALL MY POINTS**
Flura [38]

PART 1


1. The answer is low frequency electromagnetic waves are able to go around obstacles due to their larger wavelengths. This characteristic of lower frequency waves is due to their ability to diffract around obstacles such as buildings and hills. Therefore, they transmit over long distances unlike high frequency electromagnetic waves.

2. One disadvantage is interference. Electromagnetic waves of the same frequency transmitted at the same time will interfere with one other and therefore the signal will be lost or scrambled. Other electromagnetic waves such as microwaves are affected (interfered with) by weather elements.

3. Analogue signals are continuous signals with wave-like properties while digital signals are discrete signals or pulse (ons (1s) and offs (0s) that represent bits). Analogue signal is represented by a sine-wave while digital signal is represented by discrete squares waves.

4. Digital signals are less immune to eavesdropping unlike analogue signals. Analogue signal is also more prone to distortion unlike digital signal. Digital signals transmit more data than analogue signals. Digital signal draw less energy to transmit compared to analogue signal.

5. Broadcasting of TV is nowadays using digital signals due to the high number of available channels. Computers and the interne utilize digital signaling to transmit data. Controls systems such as radar system also use aspects of analogue waves. Sensors also utilize analogue waves especially transducers such as seismology equipment.


PART 2


1. One way is by sending radio waves to probes sent out in space to give them commands during exploration. Radio telescopes also pick up naturally-occurring radio waves from space and analyze the data to make conclusions about space and the astronomical objects.

2. Radio waves are used in communication by transmitting data over long distances. One example is its use TV transmission. Another is through military defense of airspace. The radio waves are used to detect enemy intrusion into restricted airspaces using radar.

3. It is common that signal from the environment will be in analogue signal format. The conversion to digital signals allows for the digital equipment in the telescope to interpret and analyze the data. Telescopes prefer digital equipment because they consume less power, handle more data, and are less prone to intrusion, and distortion, hence more secure to analogue equipment.
