Ayear has 365 days, and a day has 24 hours. if an hour has 60 minutes and a minute has 60 seconds, how many seconds are there in 1 year? 54,750 s 525,600 s 3.15 107 s 1.89 109 s

Here we need to convert year into seconds.

so lets do it step by step

first lets convert year to hours

1 year has 365 days - 365 days per year

and a day has 24 hours - 24 hours per day

therefore 1 year will have -1 year x  365 days per year x 24 hours per day

                                         = 8760 hours

next convert hours to seconds

1 hour has 60 minutes - 60 minutes per hour

and 1 minute has 60 seconds - 60 seconds per minute

since 1 year has 8760 hours

8760 hours will have - 8760 hours x 60 minutes per hour x 60 seconds per minute

                                   = 31 536 000 seconds = 3.15 x 10⁷ s

answer is 3.15 x 10⁷ s in one year

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
