Explanation:
100 CM = 1 m
45 CM = 45 / 100 = 0.45 m
hope it helps:)

Explanation:
Pls brainliest me
I had this question before
According to Gauss' law, the electric field outside a spherical surface uniformly charged is equal to the electric field if the whole charge were concentrated at the center of the sphere.
Therefore, when you are outside two spheres, the electric field will be the overlapping of the two electric fields:
E(r > r₂ > r₁) = k · q₁/r² + k · q₂/r² = k · (q₁ + q₂) / r²
where:
k = 9×10⁹ N·m²/C²
We have to transform our data into the correct units of measurement:
q₁ = 8.0 pC = 8.0×10⁻¹² C
q₂ = 3.0 pC = 3.0×10<span>⁻¹² C
</span><span>r = 5.0 cm = 0.05 m
Now, we can apply the formula:
</span><span>E(r) = k · (q₁ + q₂) / r²
= </span>9×10⁹ · (8.0×10⁻¹² + 3.0×10⁻¹²) / (0.05)²
= 39.6 N/C
Hence, <span>the magnitude of the electric field 5.0 cm from the center of the two surfaces is E = 39.6 N/C</span>
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

Answer: 1) Boils</h3>
The less air pushing down on the water effectively allows the water to boil easier. Think of the water molecules as a bunch of marbles bouncing around in a box with a lid. The less air pressure means the lid is easier to open from the force exerted by the bouncing marbles, allowing those particles to escape and turn into gas.
So in short, if you are in the mountains, then it'll take less time to cook food because water comes to a boil faster.
