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.

</span><span>Efficiency is the
measure of how efficient a process is. It is used to assess the ability of a
process in avoiding waste energy, materials, money and time in doing a
desirable output. It is calculated as;
Efficiency = useful energy ouput / total energy input</span>
<span>.40 = useful work / 200</span>
<span>useful work = 80 joules</span>
Answer:
(a) upper : 3.18 m, lower: 2.58
(b) upper : 3180 mm, lower: 2580 mm
(c) upper : 2.81 m³, lower: 1.5 m³
Explanation:
given information:
the distance ranged from 43 to 53 cm
length of cylindrical pillar = 6 cubits
diameter = 1 cubit
(a) the cylinder's length in meters
upper = 53 cm x 6 cubits
= 318 cm
= 3.18 m
lower = 43 cm x 6 cubits
= 258 cm
= 2.58 m
(b) the cylinder's length in millimeters
upper = 3.18 m
= 3180 mm
lower = 2.58 m
= 2580 mm
(c) the cylinder's volume in cubic meters
upper : V = πr²l
= π (0.53m)² (3.18)
= 2.81 m³
lower : V = πr²l
= π (0.43m)² (2.58)
= 1.5 m³
Because my dad had the dominant gene for brown hair, while my mom had the recessive gene, I now have brown hair.
Hope this helped! Good luck! :)
-- First, it can never swing to a higher elevation off the floor
than where it was when she let it go. The higher it is off the
floor, the more potential energy it has, and that's all the energy
she gave it when she lifted it to the height of her chin.
-- Second, it can't even return to THAT height, because during
its swing out and back, it's losing energy by plowing through air.
So each swing is slightly narrower, and ends slightly lower, than
the one before it.
