Answer: proton, hydrogen nucleus, hydrogen atom
Explanation:
(a) v = 2π r / t
v = 2π (0.85 m) / (0.65 s)
v = 8.2 m/s
(b) a = v² / r
a = (8.2 m/s)² / (0.85 m)
a = 79 m/s²
(c) F = ma
F = (0.013 kg) (79 m/s²)
F = 1.0 N
Covalent bonds form when electrons are shared between atoms and are attracted by the nuclei of both atoms. In pure covalent bonds, the electrons are shared equally. In polar covalent bonds, the electrons are shared unequally, as one atom exerts a stronger force of attraction on the electrons than the other.
Answer:
The fore-brain consists of the cerebrum, thalamus, and hypothalamus. Mid-brain relays information between fore-brain and hind-brain. Mid-brain plays important role in developing motor functions like eye movement, auditory functions and visual processing. The crus cerebri connects the cerebral hemispheres to the cerebellum, contains a portion having a network of neurons that is responsible for arousal and alertness.
