Why does sun seem to appear two minutes before actual sunrise?
the sun is visible to us about 2 minutes before the sunrise & about 2 minutes after actual sunset because of atmospheric refraction.By actual sunrise, we mean the actual crossing of the horizon by the sun. The time difference between actual sunset & the apparent sunset is about 2 minutes. The apparent flattening of the sun"s disc at sunrise & sunset is also due to the same phenomenon .
How is time defined?
Time is the apparent forward progress of existence. It is the quantity by which we measure change and motion of physical entities in the universe. The basic unit of time measurement is the second (s).

How do you find actual velocity?
To find the actual velocity of an object, you need to know both the magnitude and direction of its velocity. This can be determined using various methods depending on the situation. For example, in linear motion, you can calculate velocity by dividing the change in position by the change in time. In rotational motion, velocity can be found by dividing the change in angular position by the change in time.
What is the statement of time dilation by Einstein?
In a broad sense it means that you see clocks carried by people moving relative to you move slowly. This effect is totally negligible in every day life by the way, the speeds need to approach that of light for the effects to be apparent. More specifically it states that time moves slower in inertial frames moving relative to yours.

Why do you think that longitudes help in measuring time ins ted of latitudes?
Because during the course of the day, the sun's apparent longitude changes steadily, but its apparent latitude doesn't change.

During which two seasons is apparent solar time ahead of clock time?
Apparent solar time is ahead of the clock in Spring and Fall. Apparent solar time is seen while using a sundial.

Can there be a vertical dilation and reflection at the same time in algebra 2?
Yes, there can.
Why don't we experience time dilation in everyday life?
We do experience a form of time dilation in everyday life, but the effects are extremely small. Time dilation occurs due to differences in gravitational potential and velocities. In our daily lives, these differences are relatively insignificant compared to extreme situations, such as near a black hole or moving at speeds close to the speed of light, where the effects of time dilation become much more pronounced.
Does time dilation occur near the speed of light?
Time dilation always occurs, at ANY speed. The reason it was unknown for solong is that it doesn't become noticeable to us at any speed where we have anydaily experience. But as soon as we had atomic clocks capable of measuringinsanely tiny time differences, and began using them to look for time dilation,there it was, right in front of us, all over the place, in just the predicted amounts.
Why do stars change colours?
They don't actually change colour but the earth's atmosphere causes an apparent change of colour according to the time of day. And other factors like the amount of radiation emitting from the star itself.
Does the apparent size of the moon change with is phases?
No,The moon will not change size unless an asteroid hits it,that has not happened in a long time,when i was outside once,the moon was huge!but my father,and astrometer, says it cannot change size.
