Abiotic factors are factors that include non-living parts of the environment which could be significant or essential to living organisms. Water is a non-living environment and it helps in giving life to plants and other organisms. Thus deemed abiotic.

<h3>What is wave?</h3>
Wave is a periodic <u>disturbance</u> that moves away from a source which carries <u>energy</u> with it. Waves can be typified according to the <u>direction</u> of motion of the vibrating particles with respect to the direction in which the waves travel and according to <u>medium</u> .
<u>Longitudinal</u> waves vibrate perpendicularly to the direction in which the waves travel. This wave exhibits up and down motion. Longitudinal waves vibrate <u>perpendicular</u> or back and forth to the direction in which the waves travel.
<u>Electromagnetic</u> waves are combination of transverse and longitudinal waves. These move in a circular pattern as the waves pass by.
<u>Mechanical</u> waves need solid, liquid and gas medium to propagate or travel. Transverse, mechanical and surface waves are examples of mechanical waves.
Electromagnetic waves do not need <u>medium</u> to propagate. Radio waves, ultraviolet, infrared, and gamma rays are examples of <u>electromagnetic</u> waves. The nature of waves can be described through its terms, quantities and <u>propagation</u>.
The <u>crust</u> and trough refer to the highest point and lowest point of a wave pattern, respectively. The <u>magnitude</u> of a transverse wave is the maximum displacement of a particle of the medium on either side of its normal position when the wave passes. The frequency of periodic waves is the number of waves that pass a particular point for every one second while the <u>Amplitude</u> is the distance between adjacent crests or troughs.
The period is the time required for one complete wave to pass a particular point. The <u>speed</u> of the wave refers to the distance the wave travels per unit time. It is related to the frequency of the wave and wavelength through the following equation: wave speed= frequency x wavelength.

200 J of energy is wasted by the hair dryer.
Steps
- The hairdryer is provided with 1500 J of electrical energy per second
- Of this 1500 J, 1300 J of energy is actually used and converted to useful thermal energy per second
- The remaining energy, 1500 - 1300 = 200 J is dissipated
Dissipated energy
- The energy that is not efficiently transported or changed is wasted energy.
- We cannot create or destroy energy.
- An employable type of energy is created through transformation.
- Only a portion of energy that is changed or transferred can be done so in a way that is helpful.
Thus, 200 J of energy is wasted by the hair dryer.

Could be a graduated cylinder. Hope this helps :)
The pressure in the glomerulus that tends to favour filtration is known as the glomerular capillary pressure.
<span>
Glomerular capillary pressure is the main force in producing glomerular filtration and it is a fluid pressure exerted by blood within glomerular capillaries. It depends on hear contraction and resistance to blood flow by afferent and efferent arterioles in the kidney.</span>
