A chemical process with an e-factor of 1 creates less waste than an e-factor of 25 is True.
<h3>What do you mean by E-factor?</h3>
The actual amount of waste produced during the process—which is referred to as anything other than the targeted product—is known as the E factor. It considers the chemical yield as well as reagents, solvent losses, all process aids, and, in theory, fuel (although this is often difficult to quantify). There is one exception: I often did not include water in the E factor calculation. For instance, only the inorganic salts and organic chemicals present in an aqueous waste stream are taken into account; the water itself is left out. In many instances, the inclusion of water used in the process might result in very high E factors, which can make it challenging to compare processes in a meaningful way.

The upward force of the chain on the diamond would be the tension in the chain, and this tension would have to support the weight of the 45g that hangs from the chain.
mass = 45 g = 45/1000 kg = 0.045kg
Weight = mg = 0.045 * 10 ≈ 0.45N, g ≈ 10 m/s²
<span>So the upward force is ≈ </span><span>0.45N. </span>
Answer:
Wind - the perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction. Sound wave - a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
Sound wave travels faster in the air when it is with the wind. ... In contrast, when sound wave travels against the wind, that is, when it travels in the opposite direction with the wind, the speed of sound will be reduced by the wind speed, resulting in a lower speed in the upper region.

Answer:
(I). The angle of refraction on glass surface is 20.12°
(II). The critical angle of glass-water surface is 61.0°.
Explanation:
Given that,
Refractive index of glass = 1.56
Angle = 32.5
(I). We need to calculate the angle of refraction on glass surface
Using Snell's law
Put the value into the formula
(II). We need to calculate the critical angle of glass-water surface
Using formula of critical angle
Hence, (I). The angle of refraction on glass surface is 20.12°
(II). The critical angle of glass-water surface is 61.0°.
