Answer:
τ = 0
Explanation:
At the moment it is defined
τ = F x r
In tete case they give us the strength and position in Cartesian form, so it is easier to solve the determinant
τ = ![\left[\begin{array}{ccc}i&j&k\\F_{x}&F_{y}&F_{z}\\x&y&z\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Di%26j%26k%5C%5CF_%7Bx%7D%26F_%7By%7D%26F_%7Bz%7D%5C%5Cx%26y%26z%5Cend%7Barray%7D%5Cright%5D)
Let's apply this expression to the exercise
a) P = (-6 i ^ -3j ^ -6 k ^) m
F = (-6 i ^ -3j ^ -6k ^) 103 N
τ =![\left[\begin{array}{ccc}i&j&k\\-6&-3&-6\\-6&-3&-6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Di%26j%26k%5C%5C-6%26-3%26-6%5C%5C-6%26-3%26-6%5Cend%7Barray%7D%5Cright%5D)
τ = i ^ (3 6 - 3 6) + j ^ (6 6 -6 6) + k ^ (6 3 - 3 6)
τ = 0
b) P = 24i ^ + 8j ^ + 9k ^
F = 24i + 8j + 9k
τ = i ^ (72-72) + j ^ (216-216) + k ^ (24 8 - 8 24)
τ = 0
c) P = -6i + 6j-4k
F = -6i + 6j-4k
τ = i ^ (24-24) + j ^ (- 24 + 24) + k ^ (-36 + 36)
τ = 0
.d) P = 24i-8j + 9k
Let's change the sign of strength
F = -24i + 8j-9k
Tae = (I j k 24 -8 9 -24 8 -9)
Tae = i ^ (72 -72) + j ^ (- 216 + 216) + k ^ (192-192)
Tae = 0
Qualitative data gives the information of quality which can not be measured in numbers. For example: Color of eyes, softness of skin.
Quantitative data is information of quantity that can be represented in numbers. For example length and mass of any object.
Zinc is a silver-gray metal is a qualitative data, here silver gray color is quality of zinc metal which can not be measured in numbers.
Chlorine has a density of 3.2 g/L is a quantitative data. The value of density can be compared with other elements by comparing the numbers.
Gallium is not found in nature is neither qualitative nor quantitative.
Nitrogen has a melting point of –210.00 °C is a quantitative data because this is expressed in numbers.
Aluminum is a solid is a qualitative data because it tells about the state of element which can not be measured in numbers.
It would be on the top of the HR diagram, specifically, the top right.
Answer: False
Explanation:
The statement that the environment affects people, but people don't affect the environment is incorrect. It should be noted that people also affect the environment.
Some of our impact on the environment include pollution, deforestation, overpopulation, burning of fossil fuels etc. Thus has resulted in changes such as erosion, climate change, etc.
