As we move from left to right the metalic properties decreases and non-metalic property increases hence reactivity of the elements decreases.
What happen to reactivity of Metal as they move from left to right ?It happens because there are more valence shells and less attraction between valence electrons and the nucleus. Consequently, the propensity to take electrons from other atoms declines. Atoms become more electronegative as they move through a period.
The ability to lose electrons increases generally with atom size. The capacity to lose electrons increases with increasing shielding. The most active metal is to the left and down because metallic character grows down the table and diminishes across it.

What is an electric power plant?A power generation plant is a structure created to create electricity from another source of energy, such as heat energy (thermal energy) produced from coal and other fossil fuels.
Efficiency. The steam's high and low temperatures can be used to determine this: ec = Th - T c /Th =1 Tc /Th
The engine will operate most effectively when both the low and high temperatures are exceptionally high. The temperature and pressure of the environment, however, are restricted in how much the steam can expand and how low the lower temperature can be because the electric power plant is normally located on the Earth's surface.

what is the heat current through the insulation, assuming it may be treated as a flat slab with an area of 1.40 m2 ?
In order to keep the temperature in the kitchen constant, 196 W of electric power must be supplied to the heating element, which is treated as a flat slab with an area of 1.40 m2.
How to calculate electric-power input to the heating element is required to maintain this temperature?Given to us,
Area of the flat slab, A = 1.40 m²,
The thickness of the fiberglass, d = 4 cm = 0.04 m,
Inside surface of the fiberglass [tex]T_{h}[/tex], = 175°C = 175°C + 273.15 = 448.15 K,
Outside surface of the fiberglass[tex]T_{i}[/tex], = 35°C = 35°C + 273.15 = 308.15 K,
Thermal conductivity of fiberglass, K = 0.040 W/(mK),
a.)
Conduction is the process by which heat energy is been transferred due to the collisions between atoms and molecules in solids. The heat transfer in conduction is written as,
Q/t = KA([tex]T_{h}[/tex] - [tex]T_{i}[/tex])/ d
Q/t = 0.040 × 1.40(448 .15 - 308 .15)/0.04
Q/t = 196 W
Therefore, the heat current through the insulation, treating it as a flat slab with an area of 1.40 m² is 196 W.
b.)
As the electric-power input to the heating element required to maintain the temperature in the kitchen is 196 W, because as the fiberglass is constantly losing heat, therefore to maintain the temperature we need to continuously provide that amount of heat to the kitchen for which the same amount of work will be required.
Thus, the electric-power input to the heating element required to maintain the temperature in the kitchen is 196 W.
Hence, the heat current through the insulation, treating it as a flat slab with an area of 1.40 m² is 196 W and the electric power input to the heating element required to maintain the temperature in the kitchen is also 196 W.
The complete question is : An electric kitchen range has a total wall area of 1.40 m2 and is insulated with a layer of fiberglass 4.0 cm thick. The inside surface of the fiberglass has a temperature of 175 ∘C and its outside surface is at 35 ∘C. The fiberglass has a thermal conductivity of 0.040 W/(m⋅K).What is the heat current through the insulation, assuming it may be treated as a flat slab with an area of 1.40 m2?What electric-power input to the heating element is required to maintain this temperature?

Explanation:
at what distance from a 27 mw point source of electromagnetic waves is the electric field amplitude 0.090 v/m ?
The distance from the point source is 8,100m
What is distance?
Distance is a measurement of the distance apart two objects or points are, either numerically or occasionally qualitatively. Distance can be a physical length in physics or to an estimate based on other factors in everyday language (e.g. "two counties over"). The term is also frequently used metaphorically to denote a measurement of the degree of separation between two similar objects (including such statistical distance between probabilistic or edit distance between strings of text). This is because spatial cognition is indeed a rich source of conceptual metaphors in human thought. he concept of a metric space is used in mathematics to formalise the majority of these notions of distance, both literal and figurative.
The electric field intensity at a distance from a point source depends on the inverse square of the distance from the source. Therefore, the distance from the point source can be calculated using the following equation:
Distance (d) = (1/ (E/E0))2 x 27m
Where E is the electric field intensity (0.090 V/m) and E0 is the electric field intensity at a distance of 27m (27mW).
Therefore, the distance from the point source is:
d = (1/ (0.090/27))2 x 27m = 8,100m

The axis might be internal or exterior, fixed or not. But the moment of inertia (I), which is always expressed in relation to that axis, is calculated by adding the results of multiplying each particle's mass by the square of its distance from the axis in a particular body.

m[Vrf+Vgf+Vbf ]=m[Vri+Vgi+Vbi] ……………………………………..Vectorial
Along the x-axis (horizontal),
m[Vrfx+Vgfx+Vbfx ]=m[Vrix+Vgix+Vbix]
[Vrfx+Vgfx+Vbfx ]=[Vrix+Vgix+Vbix]
0+ 5+ Vbfx = 0-5+5
Vbfx = - 5m/s-------------------(1)
Along the y-axis (vertically),
m[Vrfy+Vgfy+Vbfy ]=m[Vriy+Vgiy+Vbiy]
[Vrfy+Vgfy+Vbfy ]=[Vriy+Vgiy+Vbiy]
-5+0+ Vbfy = 0+0+0
Vbfy = 5m/s ……………………(2)
q= tan^-1(Vbfy/Vbfx) = tan^-1(-5/5) = 45°
