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:
Proton and electron
Explanation:
An atom can be broken down into three constituents parts – protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge
1.8N
Explanation:
Given parameters:
Mass of the hockey puck = 0.15kg
Acceleration = 12m/s²
Unknown:
Net force = ?
Solution:
According newton's second law of motion "the net force on a body is the product of its mass and acceleration".
Force = mass x acceleration
Input the variables;
Net force = 0.15 x 12 = 1.8N

He's accelerating at 3 m/s² .
That means his speed is increasing by 3 m/s every second.
At the end of 8 seconds, his speed is (8 x 3 m/s) = 24 m/s .
He's been moving south for the whole 8 seconds.
So at the end of that time, his velocity is
24 m/s south .
