Comparison of density values determines whether an item will float or sink in water. For each of the values below, determine the

density and state whether it will float or sink in water (density = 1.00 g/mL). (a) a wooden block with sides measuring 1.53 in and a mass of 13.5 g density WebAssign will check your answer for the correct number of significant figures. g/mL float or sink (b) a metal paperclip which displaces 0.296 mL of water when determining the volume by difference and weights 111 mg density WebAssign will check your answer for the correct number of significant figures. g/mL float or sink (c) an apple which displaces 0.930 cups of water when determining the volume by difference and weighs 0.88 lb density WebAssign will check your answer for the correct number of significant figures. g/mL float or sink

Answer:

a) the object floats

b) the object floats

c) the object sinks

Explanation:

when an object is less dense than in the fluid in which it is immersed, it will float due to its weight and volume characteristics, so to solve this problem we must find the mass and volume of each object in order to calculate the density and compare it with that of water

a)

volumen for a cube

V=L^3

L=1.53in=0.0388m

V=0.0388 ^3=5.8691x10^-5m^3=58.69ml

density=m/v

density=13.5g/58.69ml=0.23 g/ml

The wooden block floats  because it is less dense than water

b)

m=111mg=0.111g

density=m/v

density=0.111g/0.296ml=0.375g/ml

the metal paperclip floats   because it is less dense than water

c)

V=0.93cups=220.0271ml

m=0.88lb=399.1613g

Density=m/v

density=399.1613/220.027ml=1.8141g/ml

the apple sinks   because it is  denser than water

Answer:

<em><u>The 'shoulder' of a road is the land to the edge of the road. On most roads without pavements, the shoulder is a strip of grass or a hedgerow. This is known as a 'soft shoulder'. On a motorway, this strip of land is hardstanding, hence the name 'hard shoulder.'</u></em>
