The answer is B: multiple orbitals of specific magnitude within an energy level
Answer:
Mass on the moon is 5.1 kg.
Explanation:
Given mass on earth = 5.1 kg
acceleration due to gravity on moon = 1.6 ms⁻².
The mass on the moon does not change because mass is the quantity of matter in the body regardless of its volume or of any forces acting on it.
Whereas the weight of the object changed.
Weight is the the force exerted on a body which is related to mass and expressed as W = mg.
W = weight of object m = mass of object and g = gravitational force

N stands for newton unit of weight.
Thus mass of the object on moon is same as on earth which is 5.1 kg.
Answer: V= 44. 6 L
Explanation: use Boyle's Law
P1V1 = P2V2
Derive to find V2:
V2 = P1V1 / P2
= 937.57 Pa( 12.5 L ) / 262.52 Pa
= 44.6 L
Answer:
Vertebrae
Explanation:
Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.
