Answer:

<h3>The answer is 0.18 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{178.5}{1000}  \\  = 0.1785

We have the final answer as

<h3>0.18 g/cm³</h3>

Hope this helps you

4) If an object is traveling at a speed of 400 m/s, how long (in hours) will it take to reach 950.5 km?
gogolik [260]

Answer:

Answer: 0.66 hours

Explanation:

{ \rm{time =  \frac{distance}{speed} }} \\  \\ { \rm{time =  \frac{(950.5 \times 1000) \: m}{400 \: m {s}^{ - 1} } }} \\  \\ { \rm{time =  {2376.25 \: s}}}

• Remember 1 second accounts for 1/3600 hours

{ \rm{time =  \frac{2376.25}{3600} }} \\  \\ { \rm{time = 0.66 \: hours}}
