Mass
Explanation:
They physical property that is not the same among the four objects is their masses.
Mass is the amount of matter contained in a substance.
- Specific heat is the amount of energy needed to raise the temperature of 1g of a substance by 1k.
- Since the materials are made of the same metal, they have the same specific heat.
- They will also have the same magnetism and electrical conductivity.
- These properties are intensive property and do not depend on the amount of matter present.
- Mass is an extensive property that depends on the amount of matter present.

Answer:Divergent boundaries -- where new crust is generated as the plates pull away from each other.
Convergent boundaries -- where crust is destroyed as one plate dives under another.
Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
Explanation:
That’s the acceleration law! This would be a good example of inertia! When in a car, if the brakes are pressed immediately, the passengers will launch forward since their bodies are still in motion!
The answer is C, because it hits a dense medium, which causes it to bounce off.
Hope I helped. :)
Answer:
a. The speed is 2.39 m/s
b. The acceleration of the block is 10.2
Explanation:
First, we have to do the energy balance where we consider two states, the first where the spring remains still and the second when it is stretched 0.400m:
Δx=
W_{ext}=20.4 Nm
To determine, the acceleration we solve the following equation for a:
