Answer:
option A
Explanation:
The correct answer is option A
Reproducible experiment is a specific experimentally produced value is said to be reproducible when there is a fair degree of consistency between measurements or observations done by different people at different locations on duplicate specimens — that is, if the test value is determined to be of great accuracy.
hence, a scientific hypothesis can be disproved with one reproducible experiment.
I'm pretty sure the answer to this question is B. If the behavior is common in certain cultures
Their behavior wouldn't be wrong or considered a psychological problem if it's part of their culture.

Answer:
Explanation:
Light year is the distance , ray of light travels in one year at the speed of 186000 mi/s
Distance traveled by light in one year
= speed x time
186000 x 365 x 24 x 60 x 60 miles
= 5.8657 x 10¹² mi
the Earth – Sun distance in light- years.
= 92.9 × 10⁶ mi. / 5.8657 x 10¹² mi light years
= 15.84 x 10⁻⁶ light years
To calculate in terms of parsec
1 degree angle
= 60 x 60 second
π /180 radian = 60 x 60 second
1 second = 3.14 / 180 x 3600
= 4.84 x 10⁻⁶ rad
one parsec = 1AU / one second
92.9 × 10⁶ mi / one second
= 92.9 × 10⁶ mi / 4.84 x 10⁻⁶ rad
= 19.19 x 10¹² mi
the Earth – Sun distance in parsec.
= 92.9 × 10⁶ mi. / 19.19 x 10¹² parsec.
= 4.84 x 10⁻⁶ parsec.
A mechanical wave is a disturbance in matter that transfers energy through the matter.
