<u>Given:</u>
Mass of asteroid, M1 = 5.00*10¹² kg
Velocity of asteroid V1 = 15.0 km/s
Mass of moon, M2 = 7.36*10²² kg
<u>To determine:</u>
The recoil velocity of moon, V2
<u>Explanation:</u>
Since the collision is perfectly inelastic, momentum is conserved. therefore,
M1 * V1 = M2* V2
V2 = M1*V1/M2 = 5.00*10¹² *15.0 /7.36*10²² = 1.02*10⁻⁹ km/s
Any liquid with a pH above 8.2.
Phenolphthalein is naturally colorless but turns pink in alkaline solutions. The compound remains colorless throughout the range of acidic pH levels but begins to turn pink at a pH level of 8.2 and continues to a bright magenta at pH 10 and above.
Answer:
I think its C. It turns the Gulf Stream northeast and the Brazil Current southwest.
(ANS1)— P4 + 5O2 ---> 2P2O5
(ANS2)— C3H8 + 5O2---> 3CO2 + 4H20
(ANS3)— Ca2Si + 4Cl2 ---> 2CaCl2 + SiCl4
