The position vector can be
transcribed as:
A<span> = 6 i + y j
</span>
i <span>points in the x-direction and j points
in the y-direction.</span>
The magnitude of the
vector is its dot product with itself:
<span>|A|2 = A·A</span>
<span>102 = (6 i +
y j)•(6 i+ y j)
Note that i•j = 0, and i•i = j•j =
1 </span>
<span>100 = 36 + y2
</span>
<span>64 = y2</span>
<span>get the square root of 64 = 8</span>
<span>The vertical component of the vector is 8 cm.</span>
It would be rock by erosion bc the rocks erode to form a volcano
The answer is gn Fertilization
Different theories in science rely on the current available knowledge that has been obtained through a certain way of data collection/that has used certain technology to obtain such data. With new technology, new datasets can be obtained that perhaps are not in line with previous theories. By improving technology, new datasets can be obtained and through this theories can be advanced, improved and developed.
Answer:
Explanation:
<u>Formula</u> :
<u>Convert volume into standard unit</u> :
⇒ 250000 cm³ × 10⁻⁶
⇒ 0.25 × 10⁶ × 10⁻⁶
⇒ 0.25 m³
<u>Solve for density</u> :
⇒ Density = 1200 kg / 0.25 m³
⇒ Density = 1200 × 4 kg/m³
⇒ Density = 4800 kg/m³
