An aggregate is one type of land resource. What is an aggregate?
LuckyWell [14K]

Answer:

a natural mixture of sand, gravel, and crushed stone

Explanation:

Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.

Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

In Science, one of the type of land resource is generally referred to as an aggregate.

Typically, an aggregate is a natural mixture of sand, gravel, and crushed stone. It's a heterogeneous mixture that is commonly mixed with bitumen, gypsum, cement, lime and several other adhesive to form mortar or concrete which are used in building and constructions.

A flute player hears four beats per second when she compares her note to a 523 HzHz tuning fork (the note C). She can match the
laiz [17]

Answer:

527 Hz

Solution:

As per the question:

Beat frequency of the player, \Delta f = 4\ beats/s

Frequency of the tuning fork, f = 523 Hz

Now,

The initial frequency can be calculated as:

\Delta f = f - f_{i}

f_{i} = f \pm \Delta f

when

f_{i} = f + \Delta f = 523 + 4 = 527 Hz

when

f_{i} = f - \Delta f = 523 - 4 = 519 Hz

But we know that as the length of the flute increases the frequency decreases

Hence, the initial frequency must be 527 Hz
