Answer:
993 m or 3257 ft
Explanation:
The captain was told to fly at at 1500 ft altitude. At the rate of 3.28 ft to 1 m, this is
metres.
Since he was at 1450 m, he thought he was above the correct altitude by
1450 - 457 = 993 m.
In feet, this is
993 * 3.28 = 3257 ft
Answer:
C) A ratio based on the mass of a carbon-12 atom
Explanation:
For each element, there is a characteristic number of protons, this number represent a type of atom and its called the atomic number
On the other hand we have the number of neutrons, and for one element which difers only on the number of neutrons, we have different isotopes from one element.
Together, protons and neutrons define the mass number
One property linked with the mass number, is the atomic mass, which is formerly expressed as "uma" (atomic mass unit)
By definition, one atom of carbon-12 (with 6 neutrons) has an atomic mass of 12 umas

Among the choices the one that is correct about relationship between the readings is letter D which is RC RD
The amount of energy before and after any energy transformations remain the same because energy cannot be created or destroyed. From the law conservation of energy; any time energy is transferred between two objects, or converted from one form into another, no energy is created and none is destroyed. The total amount of energy involved in the process remains the same.
