Answer:
C. Mass
Explanation:
The extensive property is that property of material that depends upon the amount of matter (mass) of substance. Thus, in the given options only, mass is the extensive property. All the other properties other than mass are independent of mass.
The simple method to find out the extensive property is to divide the substance into half. If that property for both individual halves also becomes half, then it is dependent on mass and an extensive property. If the property remains same as before for each half, then it is independent of mass and called intensive property such as, density, temperature, pressure, etc.
Thus the correct answer is <u>C. mass</u>
Answer:
m = T/10 = (1/10) T
Explanation:
From the question given:
∑F = ma .... (1)
∑F = T – 10m .... (2)
a = 0 m/s²
m =?
Thus, we can obtain m in terms of T as shown below:
From equation (1)
∑F = ma
a = 0 m/s²
∑F = ma = m × 0
∑F = 0
Next, substitute the value of ∑F into equation (2) to obtain m. This is illustrated below:
∑F = T – 10m
∑F = 0
0 = T – 10m
Rearrange
0 + 10m = T
10m = T
Divide both side by 10
m = T/10
m = (1/10) T
Therefore, m is (1/10) T
