The joule is an SI unit of energy that is equal to 1 kg•m2/s2. The erg is a different unit of energy that is equal to 1 g•cm2/s2
vredina [299]

Answer:

The answer to your question is: 1 J = 10, 000, 000 ergs

Explanation:

(1 kgm²/s²)(1000 g/ 1 kg) = 1000 gm²/s²

(1000 gm²/s²)(100 cm/1 m) = 1 00 000 gmcm/s²

1 00 000 gmcm/s² (100 cm / 1m) = 10 000 000 gcm²/s²

                                                       = 10 000 000 ergs

The moon's craters are remnants of meteorite collisions. suppose a fairly large asteroid that has a mass of 5.00×10^12 kg (about
Paul [167]

<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
