You use acceleration due to gravity
and 1/2 atsqr=d
therefore 1/2 * 9.8 * tsqr= d
The answer should be B. a stable isotope to a decaying isotope.
Do all you can in one big day that you have time off or work on one thing then work on the other at the same time
Given:
P1 = 400 kPa
T1 = 110 K
T2 = 235K
Required:
P2
Solution:
Apply Gay-Lussac’s
law where P/T = constant
P1/T1 = P2/T2
P2 = T2P1/T1
P2 = (235K)(400kPa)
/ (110K)
P2 = 855 kPa
The answer is d. Vacuum
Sound waves need a molecul to travel through. Gas , solid, annd liquid provide that medium.
But vacuum is just an empty space withour any moleculs in it.
Thats why in space, no one can hear you scream. Because it simply not physicsly possible
