A 20.6 g marble sliding to the right at 59.6 cm/s overtakes and collides elastically with a 10.3 g marble moving in the same dir
Likurg_2 [28]

Answer:29.8 cm/s

Explanation:

Given

mass of marble A is m_a=20.6\ gm

Initial velocity of marble A is u_a=59.6\ cm/s

mass of marble B is m_b=10.3\ gm

Initial velocity of marble B u_b=14.9\ cm/s

After collision marble B moves with velocity of v_b=74.5\ cm/s

Conserving momentum

m_au_a+m_bu_b=m_av_a+m_bv_b

20.6\times 59.6+10.3\times 14.9=20.6\times v_a+10.3\times 74.5

v_a=\frac{20.6\times 59.6-10.3(74.5-14.9)}{20.6}

v_a=29.8\ cm/s

Why is one side of the moon called "the dark side of the moon"?
Romashka-Z-Leto [24]
' 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.

Solve for the missing variable for each set. Showing ALL work through GUESS Method. Given, Unknown, Equation, Setup, Solve. 1. P
Lelechka [254]

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

M=\dfrac{P}{V}\\\\M=\dfrac{3000}{75}\\\\M = 40\ kg

Hence, P = 100 kg-m/s and M = 40 kg.

What number and type of hybrid orbital(s) form(s) when one p and one s atomic orbital mix?
Harrizon [31]

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.
