Question

please slove this three questions ​

Answer 1

Answer:

1. 386208000 seconds

2. 10 km/s

3. uninform

Explanation:

1.  We know that,

   1 year = 365 days

   1 year = 12 × 365 = 4380 days

   1 month = 30 days

    3 month = 3 × 30 = 90 days

    It means,

  12 years and 3 months = 4380 days + 90 days

  = 4470 days

   1 day = 24 hours

  1 hour = 3600 seconds

   So,

 12 years and 3 months = (4470 × 24 × 3600) seconds

 = 386208000 seconds

2.  Spaceship speed is 36000 km/h

    So, in 1 hour spaceship travel 36000 km

   Or we can say that in 60×60 second spaceship travel 36000 km

   Therefore in 1 sec spaceship travel

    =   36,000/60*60

   = 10 km/s

3.   Since same,the distance covered per unit time for the entire distance            covered is not the the motion is non-uniform.
