Calculate the mass of earth

Roman55 [17]

Answer:

$m=6.85\times 10^{24}\ kg$

Explanation:

The radius of Earth is $6.67\times 10^6\ m$

The density of an object is given by :

$d=\dfrac{m}{V}$

The density of Erth is, d = 5515 kg/m³

Where

m is the mass of the Earth

So,

$m=d\times V\\\\m=\dfrac{4}{3}\pi r^3\times d$

Put all the values,

$m=\dfrac{4}{3}\pi \times (6.67\times 10^6)^3\times 5515 \\\\m=6.85\times 10^{24}\ kg$

So, the mass of the Earth is equal to $6.85\times 10^{24}\ kg$ .

If two children, with masses of 16 kg and 24 kg , sit in seats opposite one another, what is the moment of inertia about the rot

Elena-2011 [213]

Answer:

The moment of inertia about the rotation axis is 117.45 kg-m²

Explanation:

Given that,

Mass of one child = 16 kg

Mass of second child = 24 kg

Suppose a playground toy has two seats, each 6.1 kg, attached to very light rods of length r = 1.5 m.

We need to calculate the moment of inertia

Using formula of moment of inertia

$I=I_{1}+I_{2}$

$I=(m+m_{1})\times r^2+(m+m_{2})\times r^2$

m = mass of seat

m₁ =mass of one child

m₂ = mass of second child

r = radius of rod

Put the value into the formula

$I=(16+6.1)\times(1.5)^2+(24+6.1)\times(1.5)^2$

$I=117.45\ kg-m^2$

Hence, The moment of inertia about the rotation axis is 117.45 kg-m²
