(3 m) / (2 mm/yr) = (3,000mm)/(2mm/yr) = 1,500 yrs.
This is the time required to age approx 75 generations of the best wine.
Answer:
143975.31 N/m
Explanation:
Hook's law: Hook's law states that the force applied to an elastic material is directly proportional to its extension, provided that the elastic limit is not exceeded.
From Hook's law,
F = ke................... Equation 1
Where F = applied force, k = spring constant, e = extension/depression.
Make k the subject of the equation,
k = F/e ................. Equation 2
From the question,
The weight acting on the bathroom scale is the same as the applied force.
F = mg................ Equation 3
Substitute equation 3 into equation 2
k = mg/e ............. Equation 4
Given: m = 119 kg, e = 0.81 cm = 0.0081 m.
Constant: g = 9.8 m/s²
Substitute into equation 4
k = 119(9.8)/(0.0081)
k = 143975.31 N/m.
Hence the effective spring constant = 143975.31 N/m
The value of the swimmer's power output is calculated by dividing the work done by the time it took for the work to be completed. From the given in this item,
P = 3560 J/ 55 s = 64.73 W
Rounding off to two significant figures will give us 65 W.
Answer:
The correct answer is - Damage to the nerves that control the diaphragm.
Explanation:
Abdominal breathing is a condition in which inferior half of the lungs can be seen relaxing or contracting and expanding with the breath. This condition occurs due to the various conditions that lead to the respiratory.
It is cause due to the damage to nerves that control the diaphragm. The phrenic nerve is one of the nerve of diaphragm initiates in the neck and passes down.
Thus, the correct answer is - Damage to the nerves that control the diaphragm.
The phrenic nerve is a nerve that originates in the neck (C3–C5) and passes down between the lung and heart to reach the diaphragm.
