A 10cm3 sample of copper has a density of 897g/cm3. What is the mass of the sample?

Question:-

A 10cm³ sample of copper has a density of 897g/cm³. What is the mass of the sample ?

Answer:-Given:-

Density of sample of copper is 897g/cm³.

Volume of sample of copper is 10cm³.

To Find:-

The mass of the sample.

Solution:-

We know,

So, Mass = 897g/cm³ × 10cm³

Mass = 8970 g

The mass of the sample is 8970 g. [Answer]

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
