1. What is the acceleration of a point on the edge of a 0.30 m diameter grinding wheel rotating at 1600 rpm?

Complete Question

1. What is the linear speed of a point on the edge of a 0.30 m diameter grinding wheel rotating at 1600 rpm?

2. What is the acceleration of the point?

Answer:

$v = 25.14 \ m/s$

$a = 4013.5 \ m/s^2$

Explanation:

From the question we are told that

The diameter is $d = 0.30 \ m$

The angular speed is $w = 1600 \ rpm = \frac{ 1600 * 2 * \pi }{60 } = 167.6 \ rad /s$

Generally the is mathematically represented as

$r = \frac{d}{2} = \frac{0.30}{2 } = 0.15 \ m$

Generally the linear speed is mathematically represented as

$v = wr$

$v = 167.6 * 0.15$

$v = 25.14 \ m/s$

Generally the acceleration is mathematically represented as

$a = \frac{v^2 }{r}$

$a = \frac{25.14^2}{0.15}$

$a = 4013.5 \ m/s^2$

Which of the following does not contribute to eutrophication ?

sveticcg [70]

Answer: A. Sediment

Eutrophication is a phenomena in which a water body gets enriched with minerals and nutrients frequently entered into water body due to run-off from the land, which facilitates dense growth of plants especially on the superficial layers of water body. Decaying organisms, fertilizers and pollution all add nutrients and minerals necessary for plant growth specifically remain floating on the superficial layers of water where plant growth takes place but sediments gets settled at the bottom of the water body, the minerals present in it remain settle at the bottom and hence, does not contribute to eutrophication.
