Answer:
<h2>The answer is </h2><h2>A. slows heat flow.</h2>
Explanation:
An insulator is a material that impedes the movement of heat or electric current from flowing.
Theoretically good heat insulators stops the movement of heat, while practically this insulation can only be slowed down.
Hence from the options listed the correct answer practically is
<h2> A. slows heat flow.</h2>
Answer:
inhibitor
Explanation:
Inhibitors slow down chemical reactions. Inhibitors slow down or stop the activity of an enzyme.
The visible<span> light </span>spectrum<span> is a fractional </span>part of the electromagnetic spectrum, which is visible<span> due to our eyes, which are light receptors. </span>Invisible spectrum<span> are things like UV </span>spectrum<span> which falls outside the human </span>visible<span> range.</span>
So,
Solids - definite shape, definite volume Liquids - no definite shape, definite volume
<span>The formulas are,
v1d1² = v2d2² ........ (1)
h = (v2²-v1²)/2g ...... (2)
Given that,
v1 = 1.71 m/s
we assume that the stream has decreased by a factor
d2 =0.805d1
then,
v1d1² = v2 (0.805d1)²
cancelled both side d1² then we get,
v1 = v2 (0.805)²
v1 = v2 (0.648025)
Sub v1 = 1.71,
1.71 = v2 (0.648025)
v2 = 1.71/0.648025
v2 = 2.638787083831642
v2 = 2.64 m/s
The vertical distance formula,
h = (v2²-v1²)/2g
We know that value of gravity constant is 9.8 m/s²
h = {(2.64)² - (1.71)²)/2(9.8)
h = {(6.9696) - (2.9241)}/19.6
h = (4.0455)/19.6
h = 0.2064030612244898
h = 0.21 cm
Therefore, the vertical distance h = 0.21 cm.</span>
