Answer:
N₂ / N₁ = 13.3
Explanation:
A transformer is a system that induces a voltage in the secondary due to the variation of voltage in the primary, the ratio of voltages is determined by the expression
ΔV₂ = N₂ /N₁ ΔV₁
where ΔV₂ and ΔV₁ are the voltage in the secondary and primary respectively and N is the number of windings on each side.
In this case, they indicate that the primary voltage is 9.0 V and the secondary voltage is 120 V
therefore we calculate the winding ratio
ΔV₂ /ΔV₁ = N₂ / N₁
N₂ / N₁ = 120/9
N₂ / N₁ = 13.3
s good clarify that in transformers the voltage must be alternating (AC)
Answer: Physical component- state of physiological arousal triggered by autonomic nervous system
Behavioral component- outward expression of emotion, including facial expression and behavior
Cognitive component- appraisal of the situation determine which emotion we are experiencing and why.

Force is equal to mass x acceleration. The heavyweight is packing both greater acceleration and mass than the tissue paper.
When his fist comes in contact with the paper, the tissue reacts by exerting its own opposite force, providing a tiny bit of resistance until the fist breaks it apart and passes through.
The fist, although by a a very tiny amount, is decelerated (slowed down) by the paper before it breaks through.
Compaction is when sediments are buried deeply, which causes pressure because of the weight of the layers above them. This squashes the grains together more tightly. Cementation is where new minerals stick the grains together
Answer:
mark brainliest
Explanation:
When a greater normal force is exerted, the actual contact area increases, and it is found that the friction is proportional to this area. Two rough surfaces in contact have a much smaller area of actual contact than their total area.
