Answer:6 times the range of Earth
Explanation:
Given
first projectile is launched and second Projectile is launched on moon surface from same height
acceleration due to gravity on moon is
Range of Projectile
Where u=initial velocity
=launch angle
so range on moon is six times as compare to range on earth
from the molecular formula of CH₄ , we see that
one molecule of CH₄ contains 1 atom of carbon and 4 atoms of hydrogen .
in the same way , if we have 1 mole of CH₄ , it will contain 1 mole of carbon and 4 moles of hydrogen
similarly , if we have 5 moles of CH₄ , it will contain 5 x 1 mole of carbon and 4 x 5 moles of hydrogen
so in 5 moles of CH₄ , we have 5 moles of carbon
To determine the speed relative to the ground, since the ground is our reference frame, it would be v = 0, for the kid on the skateboard, you would need to take into account the speed that he/she is going and the speed of the keys thrown at.
I believe.
