Answer:
states that the rate of diffusion of gases is inversely proportional to their square roots
Answer:
f = 0.4 Hz
Explanation:
The frequency of rotation of an object in order to achieve required centripetal or radial acceleration, can be found out by using the following formula:
f = (1/2π)√(ac/r)
where,
f = frequency of rotation = ?
ac = radial acceleration = 34.1 m/s²
r = radius = length of beam = 5.55 m
Therefore,
f = (1/2π)√[(34.1 m/s²)/(5.55 m)]
<u>f = 0.4 Hz</u>
Birth rate 10/1000 = +population
Death rate 9/1000 = -population
Immigration rate 3/1000 = +population
Emigration rate 7/1000 = -population
10/1000 - 9/1000 + 3/1000 - 7/1000= -3/1000
Growth rate = (-3/1000)(100%)= -0.3%
