Independent variable are the light intensity that what we change and dependent variable are the rate of transpiration that what we measure.
Photosynthesis is the process that can be used by the plants and other animals to covert light energy into the chemical energy. Photosynthesis is the main source of food in the earth.
Photosynthesis is the process in which oxygen is released. For survival oxygen is very important, from this process we obtain sufficient amount of oxygen.
The dependent variable is the rate of transpiration and the independent variable is time.The dependent variable is the rate of transportation because it is depends on the environmental factor the plant is placed.
Thus,Independent variable are the light intensity that what we change and dependent variable are the rate of transpiration that what we measure.

Dependent variable: The rate of transpiration (what YOU MEASURE)
Explanation:
Colloidal solutions, or colloidal suspensions, are nothing but a mixture in which the substances are regularly suspended in a fluid. ... Colloidal systems can occur in any of the three key states of matter gas, liquid or solid. However, a colloidal solution usually refers to a liquid concoction.
Answer:
Colloidal solutions, or colloidal suspensions, are nothing but a mixture in which the substances are regularly suspended in a fluid.
The answer is; Transverse waves
Fiber optic cables transmit information using monochromatic light pulses. All electromagnetic waves (light included) are transverse waves. This means that the particles move perpendicular to the direction of the wave. This is unlike sound waves that are longitudinal waves (particles move parallel to the direction of the wave).
Fiber optic cables transmit data using light waves, which are essentially electromagnetic waves. The wave characteristics of light, especially total internal reflection, interference, and diffraction, facilitate effective data transmissions through these fibers. Factors like high bandwidth, low signal loss, and reduced crosstalk further contribute to their advantage over traditional cables.
Based on the principles of optics, electromagnetic waves, particularly light waves, are what you could find in a fiber optic cable. Fiber optic cables work by transmitting data as pulses of light through strands of fiber made from glass or plastic. This process utilizes the characteristic phenomenon of total internal reflection. When light rays enter the fiber, they bounce off the walls of the fiber cable, undergoing multiple total internal reflections, which ensures that no light escapes the fiber and all signals are conveyed effectively.
Light's wave characteristics are crucial in enabling this functionality. The wave nature of light helps explain properties such as interference and diffraction, essential for the transmission of data in fiber optic networks. These principles are especially relevant when light interacts with small objects such as the core/cladding of the fiber, a subject area often referred to as wave or physical optics.
Another advantage is the high bandwidth of fiber optics, made possible because lasers can emit light with characteristics that allow far more data transmission than electric signals on a single conductor. Meanwhile, properties like low loss and reduced crosstalk enhance the functional superiority of fiber optic cables over traditional copper cable systems.

Answer:
Which equation represents the reaction of a weak acid with water? the equation is : HCl + H2O H3O+ + Cl- HCO3– + H2O H2CO3 + OH– H2O H + + OH- HCOOH + H2O H3O+ + HCOO
Explanation:
hope it helps : )
Answer:
Hey mate, here is your answer. Hope it helps you.
HCOOH + H2O ↔ H3O+ + HCOO-
Explanation:-
A strong acid is one which completely dissociates into its corresponding ions in aqueous medium.
In contrast, a weak will only partially dissociate such that there is an equilibrium between the dissociated ions and the undissociated acid.
In the given examples:
HCl, HCO3- and H2CO3 are all strong acids. However, HCOOH i.e. formic acid is a weak acid which dissociates in water to form H3O+ and formate ion, HCOO-
HCOOH + H2O ↔ H3O+ + HCOO-

the specific heat of the resulting Nacl solutions is 4.06j/gc
calculate the heat of neutralisation of hcl and naoh in kj/mol nacl products
Answer:
62.12kJ/mol
Explanation:
The neutralization reaction of HCl and NaOH is:
HCl + NaOH → NaCl + H₂O + HEAT
You can find the released heat of the reaction and heat of neutralization (Released heat per mole of reaction) using the formula:
Q = C×m×ΔT
Where Q is heat, C specific heat of the solution (4.06J/gºC), m its mass and ΔT change in temperature (27.5ºC-20.0ºC = 7.5ºC).
The mass of the solution can be finded with the volume of the solution (50.0mL of HCl solution + 50.0mL of NaOH solution = 100.0mL) and its density (1.02g/mL), thus:
100.0mL × (1.02g / mL) = 102g of solution.
Replacing, heat produced in the reaction was:
Q = C×m×ΔT
Q = 4.06J/gºC×102g×7.5ºC
Q = 3106J = 3.106kJ of heat are released.
There are 50.0mL ×1M = 50.0mmoles = 0.0500 moles of HCl and NaOH that are reacting releasing 3.106kJ of heat. That means heat of neutralization is:
3.106kJ / 0.0500mol of reaction =
