Answer: C. illuminance of a surface.
a) Incandescence: The phenomenon of light emission by a body as a result of high temperature.
B. Luminous flux : It is the quantity of the energy of the light emitted per second in all directions.
C. Illuminance of a surface :describes the quantity of light emitted by a light source or received at a surface.
D. luminous intensity : the quantity of visible light that a point source radiates in a given direction.
Releasing any species into an environment it's not adapted to, or native to is dangerous because the species lacks the necessary adaptations to survive in the environment.
In the example of the frog, releasing it into a grassland would be a bad idea because the frog needs not only a "moist" area to thrive but it needs places to hide and plenty of insects to feed off of. Also, for reproduction it would need a pond, or some kind of water source!
I hope this is helpful!
The animal that is hunted and consumed is considered the prey
Answer:
2.7 x 10¹¹ m
Explanation:
Given,
time = 15 minutes
1 min = 60 s
15 min = 15 x 60 = 900 s
Distance of Curiosity from earth
D = Speed x time
Speed of light = 3 x 10⁸ m/s
D = 3 x 10⁸ x 900
D = 2.7 x 10¹¹ m
Distance of curiosity from earth is equal to 2.7 x 10¹¹ m
Answer:
field B = µ₀c I / 2πr
The field in the xy plane due to the fact that the two wires are perpendicular to the plane Bx and By are everywhere 0 on the plane.
a) Midway between, the Bz components cancel, so <0, 0, 0> T
b) Bz = µ₀ x I / 2πa + µ₀ x I / 2π(3a) = (µ₀ x I / 2π)(1/a + 1/3a)
Bz = (µ₀ x I / 2πr)(3/3a + 1/3a) = (µ₀x I / 2πr)(4 / 3a) = 2µ₀ x I / 3πa
c) By symmetry, Bz = -2µ₀ x I / 3πa (that is, down into the plane)
