(a). If the temperature of a substance is increased the density of it will also increased. The temperature is directly proportional to the density because the molecular activity of the substance will be affected by the temperature
(b).The mass of the substance doesn't at all. Because the amount of matter inside the substance cannot be affected by the temperature except that its water
Answer:
Granite is durable, as it is hard and tough.
Gneiss has resistance to pressure and mechanical impacts
Explanation:
Granite is an igneous rock. It is mostly used in building works and construction because they are very durable. They are hard and tough and they have no internal structures.
Gneiss is used for flooring, ornamental stone, tombstones because of the fact that it shows resistances to pressure and also mechanical impacts.
<u>how they are formed in nature:</u>
In nature, granite is formed from the cooling down of hot molten magma and it's solidification before it reaches the surface of the earth.
In nature, gneiss is as a result of igneous rock or sedimentary rocks metamorphosing. Gneiss and granite are kind of similar. When subjected to great heat, granite becomes gneiss

Answer: Period = 0.2 seconds; frequency = 5Hz
Explanation:
Number of oscillations = 50
Time required = 10 seconds
Period (T) = ?
Frequency of the oscillations (F) = ?
A) Recall that frequency is the number of oscillations that the mass spring system completes in one second.
i.e Frequency = (Number of oscillations / time taken)
F = 50/10 = 5Hz
B) Period, T is inversely proportional to frequency. i.e Period = 1/Frequency
T = 1/5Hz
T = 0.2 seconds
Thus, the the period and frequency of the oscillations are 0.2 seconds and 5Hz respectively.
