Imagine a 10 kg chunk of aluminum (density = 2.7 g/cm3) and a 10 g chunk of iron (density = 7.9 g/cm3). which of the following is true? a. the chunk of iron is more massive than the chunk of aluminum. b. the chunk of aluminum's volume is smaller than the chunk of iron's volume. c. the chunk of iron's volume is smaller than the chunk of aluminum's volume. d. both objects have the same volume.

 C. The chunk of iron's volume is smaller than the chunk of aluminum's volume.

Step-by-step explanation:

Given: The mass of aluminum chunk = 10 kg

In grams , the mass of aluminum chunk = 1000 g   [∵ 1 kg = 1000 g]

The mass of iron chunk =10 g

i.e The chunk of aluminum is more massive than the chunk of iron.

Density of Aluminum chunk =

Density of iron chunk =

The formula of volume is given by :-

Clearly, The chunk of iron's volume is smaller than the chunk of aluminum's volume.

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

i googled it and this is what i got i don't know how it is. sorry.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
