Answer:
light waves can travel in vacuum but sound waves require a medium to travel
also light waves are electromagnetic waves while sound waves are mechanical, light waves are transverse waves while sound waves are longitudinal waves
They have similar distances from the sun therefore receive similar amounts of solar energy but Venus has no atmosphere to protect it so greater variation in temp.
Both are rock planets unlike those further away from the sun which, because of their distance receive less solor energy are cold, are ice planets
Is b= acid + base - water + salt.
Well at the fourth half-life it would be 6.25% so if you continue calculating the answer would be B.
From p1v1/t1 = p2v2/t2
pressure unchanged ... cancelled out
v1=605 , t1=27C = 300K,
t2=-3C = 270K
***remember temperature must be in Kelvin
we got
605/300 = v2/270
v2 = 545
