Conductor because it creates heat.
You want all those boxes filled in (0,0)
<span>In order to determine the speed of the entire assembly, we employ conservation of momentum. Momentum p = mv where m is the object's mass and v is the velocity.
The putty ball's initial momentum p1 = 0.3kg*6m/s = 1.8 kg*m/s
That momentum is conserved, so the momentum of the new system having mass 0.3 kg + 1.2 kg = 1.5 kg is:
1.8 kg*m/s = 1.5kg*v. Solving for v, we find that the velocity is 1.2 meters/second.</span>
Answer:
Mass of the cube is 23350 grams.
Explanation:
It is given that,
Side of cube, a = 15 cm = 0.15 m
Density of the cube, 
We need to find its mass. It can be calculated using the formula of density as :

, V is the volume of cube


m = 23.35 kg
or
m = 23350 grams
So, the mass of the metal cube is 23350 grams. Hence, this is the required solution.
