Here is the correct question
A constant electric field E = 100 N/C pointing along the positive x-axis is present throughout a region of space that includes the plane bounded by the y and z axes and the lines y = 50 cm and z = 50 cm. The electric flux through the plane's surface, in N ⋅ m 2/C, is
Answer:
25 Nm²/C
Explanation:
given that
The constant electrical field E = 100 N/C
the field lines y and z = 50 cm and 50 cm respectively
= 0.5 m and 0.5 m
For constant electric field, the flux = electric field x area through which field lines are passing
i.e Flux = (100 ×0.5 × 0.5) Nm²/C
= 25 Nm²/C
Therefore; The electric flux through the plane's surface, in Nm²/C is = 25 Nm²/C
Answer:
162.8 K
Explanation:
initial current = io
final current, i = io/8
Let the potential difference is V.
coefficient of resistivity, α = 43 x 10^-3 /K
Let the resistance is R and the final resistance is Ro.
The resistance varies with temperature
R = Ro ( 1 + α ΔT)
V/i = V/io (1 + α ΔT )
8 = 1 + 43 x 10^-3 x ΔT
7 = 43 x 10^-3 x ΔT
ΔT = 162.8 K
Thus, the rise in temperature is 162.8 K.
Answer:
When you are running the most important force that you should understand is friction. Friction is a force that opposes movement between two objects, but for runners friction makes you faster. Friction gives you a better and more efficient way to use your energy into speed.
Answer:
When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
Explanation:
The system can respond to internal and external influences and make adjustments to keep your body within a degree or two of your normal. The hypothalamus and your autonomic nervous system work with your skin, sweat glands, muscles and even your blood vessels to keep your temperature normal. As in other mammals, thermoregulation is an important aspect of human homeostasis. Most body heat is generated in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. Some nuts like peanuts, almonds, cashews, pistachios, and dates are also beneficial in winter. These nuts speed up your metabolism and increase your body temperature, eventually making you feel hot.
The "D) People perceive objects as a whole" statement best describes an abductive reasoning. The abductive reasoning often has incomplete information as the base of its reasoning and the conclusion for this type of reasoning is not absolute. There will always be additional pieces of evidence and factors that could change the conclusion of this reasoning. Therefore<span> D statement is the most suitable answer.</span>
