Answer: 70712.44 ly
Using the following time dilation formula:
where is the time measured in the moving frame, is the speed of the moving frame, is the speed of light and is time measured in other frame.
Inserting the values:
Therefore, when a trip to a star 1000 ly years away is made with speed 0.99 c, 70712.44 ly would have passed on Earth.
Approximately 999 years will pass on Earth while you are gone.
The formula for time dilation is t′ = t1 - (vc)2 / c.
To calculate how many years will pass on Earth while you are on this trip, we need to determine the time experienced by the astronaut and then use the time dilation formula.
According to the information provided, the astronaut travels at an average speed of 0.99c, so v = 0.99c. The star is located 1,000 light-years away, so t1 = 1,000 years.
Plugging these values into the time dilation formula, we get:
t′ = 1,000 years - (0.99c)2 / c = 1,000 years - 0.9801 years = 999.0199 years.
Therefore, approximately 999 years will pass on Earth while you are gone.

- Atoms are not divisible into smaller particles.
- It is impossible to define the mass of an atom.
- The atom contains no particles that have a neutral charge.
Answer:
- The positive charge in an atom is concentrated in one location.
Explanation:
In Rutherford's experiment when alpha particles are projected towards the gold foil then he observed that major proportion of the alpha particles are moved out undeviating.
This shows that alpha particles which are positively charged are not repelled by other positive charge of nucleus as it is concentrated at small part of atom
because very few alpha particles are reflected back at 180 degree so he concluded that nucleus charge is concentrated at very small space
and that part is termed as nucleus.
so correct answer is
- The positive charge in an atom is concentrated in one location.

Answer:
1. Evaporation: The water evaporates from the water bodies like seas and oceans.
Transpiration: The water evaporates from the plant's leaves.
2. Condensation: The evaporated water condenses to liquid droplets which to form clouds.
3. precipitation: When the cloud becomes heavy, water rains down. This is known as precipitation.
The water rains down in rivers and seas and oceans. From rivers, it runs off back into the seas.
