What evidence do we have that distant galaxies are moving away from us?

Answer:

... because Edwin Hubble was the man that proved it from his observations.  He proved that there is a direct relationship between the speeds of distant galaxies and their distances from Earth. This is now known as Hubble's Law.

Answer:

Using the redshift of electromagnetic spectra you can determine the current distance and speed of remote galaxies. Observing the same galaxies over time you can determine that the galaxies are moving away from us and accelerating. You will also note that their speed is proportional to their distance (the further away they are the faster they are moving), which is a feature of metric expansion.

Ne4ueva [31]

Answer:

60 sec.

Explanation:

The first person has to travel 200m at 2 m/s. It will take him 200/2=100 seconds to reach the gate. The second person is moving towards the gate at 2 + 3 meters per second so it will take her 200/5 = 40 seconds to reach the gate. Therefore, person #1 needs an extra 100-40 = 60 seconds.

Day and night kennel charges $20 per day plus a one-time food fee of $15 to board a pet. Bark time hotel charges $30 per day plu
Sonbull [250]

The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let y represent the total charges for for boarding a pet in x days.

Day and night kennel charges $20 per day plus a one-time food fee of $15 to board a pet. Hence:

y = 20x + 15

Bark time hotel charges $30 per day plus a one-time food fee of $5. Hence:

y = 30x + 5

The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.

Hi! can someone tell me what a holy communion is? it's for my religious education essay. thanksx
mojhsa [17]

Answer:

Explanation: The Holy Communion is a practice in Christianity, also recognised as one of the 7 sacraments (First Holy Communion). This is where a child (typically 7-10 years old) has their first Eucharist and confession. This is when they go to the priest and confess their sins, and can then claim the Eucharist, which is when they eat "the body of Christ". The small piece of bread given is known as "the body of Christ", and the wine as Jesus's blood. (....check next answer for the rest)

monicawiszowata avatar

After receiving the first Holy Communion, this is simply a natural procession in church. Priest will say "The Body of Christ", the receiver says "Amen", and eats the bread. Upon eating the bread, they do the sign of the cross. This is done to symbolise that Christ is among the receiver of the Communion.

Which describe radio waves? check all that apply. Low frequency high frequency short wavelength long wavelength low energy trans
drek231 [11]

Answer:

Low Frequency, Long Wavelength, and Low Energy Transfer

Explanation:

Radio waves are on the larger(and lower frequency) side of the electromagnetic spectrum. These longer wavelengths mean that radio waves have a lower frequency because it takes longer for larger waves to travel. Therefore, less radio waves can travel a certain distance in a minute than a wave of a shorter wavelenght(and therefore lower frequency). Radio waves are considered a low-energy transfer wave. This is because they can be used in most environments for communication, air-traffic control, and broadcasting with little to no harm to the organisms around them. Even though radio waves can be found all around us, because they don't carry much energy, we aren't harmed by the radio waves.
