Answer:29.8 cm/s
Explanation:
Given
mass of marble A is 
Initial velocity of marble A is 
mass of marble B is 
Initial velocity of marble B 
After collision marble B moves with velocity of 
Conserving momentum
' A ' and ' C ' both say the same thing, and both are correct statements. But they're not a reason to call any part of the moon a "dark side". No part of the moon is dark for more than 2 weeks at a time, and the only reason to talk about a "dark side" of it is ignorance.
Answer:
(1) P = 100 kg-m/s (2) M = 40 kg.
Explanation:
We need to solve the missing variable :
1. P=?, M=20 kg, V=5 m/s
If M is mass, V is velocity, then momentum P is given by :
P = MV
P = 20 kg × 5 m/s
P = 100 kg-m/s
(2) P= 3000 kg(m/s), M=?, V=75 m/s
Hence, P = 100 kg-m/s and M = 40 kg.
Since the y axis stayed consistent, we can assume it did not move at all.
(So your answer would be A)
Two equivalent hybridized orbitals will form from the mixing of one s-orbital and one p-orbital, that is (sp) orbital.
<h3>What are orbitals?</h3>
Orbital is the place around nucleus where mostly the electrons are present. There are four types of orbitals are present, s, p, d, and f.
The orbitals that are formed by the mixing of these orbitals are called hybrid orbitals.
Thus, two equivalent hybridized orbitals will form from the mixing of one s-orbital and one p-orbital, that is (sp) orbital.
