Answer:
17. h = l − l cos θ
18. 1.40 m
Explanation:
Let's call d the height of the triangle. We can then say:
h = l − d
Using trig, we can write d in terms of l and θ:
d = l cos θ
h = l − l cos θ
If l = 6 m and l cos θ = 40°:
h = 6 − 6 cos 40
h ≈ 1.40
Answer:
In the analytical method,
- Resolve the vectors into the perpendicular components of the Cartesian coordinates.
- Calculate the magnitude of the resultant vector using the Pythagoras theorem.
Explanation:
- There are two methods to find the magnitude of the resultant vector.
- One is the geometrical method and the other one is the analytical method.
- In the geometrical method, all the vectors are connected the head to tail with the appropriate magnitude and the resultant vector is obtained by joining the initial point and the final point by a vector in the reverse direction. The magnitude of the resultant vector is given by the length of the line.
- In the analytical method, all the vectors are resolved into the perpendicular components.
- Using Pythagoras theorem, the magnitude of the resultant vector can be obtained
- If A and B are the two vectors forming an angle ∅ between them, then the magnitude of the resultant vector is given by the formula

Answer:
Water (H₂O) and Carbon dioxide (CO₂)
Explanation:
Photosynthesis usually refers to the process by which the green plants can synthesize their own food in the presence of sunlight, water, carbon dioxide, and light. This process helps in the conversion of light energy into chemical energy.
In addition to the sunlight and chlorophyll, the process of photosynthesis requires water as well as carbon dioxide. The plants are comprised of green pigments on their leaves that are commonly known as chlorophyll. These pigments absorb the water molecules and carbon dioxide gas that helps in synthesizing their food.
The equation for the process of photosynthesis is given below:
6CO₂ + 6H₂0 + (energy) → C₆H₁₂O₆ + 6O₂
