Identifying Characteristics of Solids

Karolina [17]

The solids whose particles occur in a definite pattern are called crystaline solids.

<h3>What is a crystalline solid?</h3>

The term crystalline solid has to do with the type of solid in which the atoms that components that make up the solid are all in definite positions and occur in a regular repeating pattern.

The particles of a solid are found in fixed positions. The solids whose particles occur in a definite pattern are called crystaline solids.

A coin is placed 19 cm from the axis of a rotating turntable of variable speed. When the speed of the turntable is slowly increa

photoshop1234 [79]

Answer:

0.22

Explanation:

Given that

Radius of turntable, R = 19 cm = 0.19 m

Speed of rotation the turntable, f = 32 rpm = 32/60 = 0.533 rev/sec

from free body diagram and forces resolution, we have

μ(s) * m * g = m * v²/R

μ(s) * g = v²/R

μ(s) = v² / gR, recall, v = wr, so

μ(s) = w²R² / gR

μ(s) = w²R / g, recall again, w = 2πf

μ(s) = (2πf)²R / g, on substituting,

μ(s) = (2 * 3.142 * 0.533)² * 0.19 / 9.8

μ(s) = 3.35² * 0.19 / 9.8

μ(s) = 2.13 / 9.8

μ(s) = 0.22

fprintf('\nNumber of blades = 3:\n-------------------------\n')

power(3)

fprintf('\nNumber of blades = 4:\n-------------------------\n')

power(4)

function power(n)

switch n % n = number of blades

case 2

I threw a plastic ball in the pool for my dog to fetch. The mass of the ball was 125g. What must the volume be to have a density

Stells [14]

Answer:

250 mL

Explanation:

Density equation:

$Density = \frac{mass}{volume}$

Variables:

D = density

m = mass

V = volume

Solve:

M = 125 g

D = 0.500 g/mL

V = ?

$0.500 g/mL = \frac{125 g}{V}$

V = 250 mL
