7) You think you have found a diamond. Its mass is 5.28 g and its volume is 2 cm3. Calculate the density
lesya [120]

Answer:

\boxed {\tt d=2.64 \ g/cm^3}

\boxed {\tt Not \ a \ diamond}

Explanation:

Density can be found by dividing the mass by the volume.

d=\frac{m}{v}

The mass is 5.28 grams and the volume is 2 cubic centimeters.

m=5.28 \ g\\v= 2 \ cm^3

Substitute the values into the formula.

d=\frac{5.28 \ g }{2 \ cm^3}

Divide.

d=2.64 \ g/c^3

The density of the unknown substance is 2.64 grams per cubic centimeter.

The density of a diamond is about 3.5 grams per cubic centimeter. Since 2.64 is not equal to 3.5, the unknown substance is not a diamond.

A uniform rod of mass M and length L is free to swing back and forth by pivoting a distance x from its center. It undergoes harm
Alisiya [41]

Answer:

The moment of inertia is 0.7500 kg-m².

Explanation:

Given that,

Mass = 2.2 kg

Distance = 0.49 m

If the length is 1.1 m

We need to calculate the moment of inertia

Using formula of moment of inertia

I=\dfrac{1}{12}ml^2+mx^2

Where, m = mass of rod

l = length of rod

x = distance from its center

Put the value into the formula

I=\dfrac{1}{12}\times2.2\times(1.1)^2+2.2\times(0.49)^2

I=0.7500\ kg-m^2

Hence, The moment of inertia is 0.7500 kg-m².

The person selling the bananas in the market says that they have a 'weight' of 1 kg. Explain what is
Bas_tet [7]

In physics weight is the force exerted on a body by gravity so, the seller should have said it has a mass of 1 kg because mass is the amount of matter in an object.
