To solve this problem we will proceed to use Newton's second law for which the mass (m) multiplied by the acceleration (a) is defined as the Force (F) applied on a body, mathematically that is,

F = ma

According to the statement for the first object, the acceleration is,

a = \frac{F}{m} \rightarrow 1^{st} Object

For the second object the acceleration is,

8a = \frac{3F}{m_2} \rightarrow 2^{nd} Object

Solving for the mass of the second object,

m_2 = \frac{3F}{8a}

m_2 = \frac{3F}{8(F/m)}

m_2 = \frac{3}{8}m

Therefore the correct answer is D.

Which type of mine involves digging tunnels and shafts deep underground?
mel-nik [20]

The mine involves digging tunnels and shafts deep underground is the underground mining.

<h3>What is mining?</h3>

Mining is the digging of the Earth deep down in search of some precious elements or resources found on Earth.

Underground mining is the digging down into the earth in order to create tunnels. The shafts need to be inserted into those tunnels so that it reaches the deposits of resources.

Thus, underground mining involves digging tunnels and shafts deep underground.
