Answer:
The correct answer is C
Explanation:
In this exercise you are asked to analyze the following situation: for a fixed observer, the two balloons are launched at the same time.
If the observer is mobile moving towards the positive side of axis ax we have several
possibilities when starting the movement
* the observer is to the left of the two balloons
* the observer is between the two balloons
* the observer is to the right of the two baloomls
The time it takes for the signal to arrive to know which ball goes first is
v = d / t
t = d / v
If the signal goes at the speed of light, the speed is a constant and the time will depend only on the distance, so we see that the trigger changes depending on the relative position between a given ball and the observer.
Consequently, it will be seen which comes out first, depending on the relative position with the observer.
The correct answer is C
Answer:
r = 1.56 m
Explanation:
B = μ₀I/2πr
r = μ₀I/2πB
I = 9.00 / 52.0 = 0.173 A
μ₀ = 4πe-7 T•m/A
r = 4πe-7(0.173)/2π(2.22e-8)
r = 2e-7(0.173)/(2.22e-8)
r = 1.5592... ≈ 1.56 m
Heat = m x c x Δθ
2000 = 2 x c x 5
Specific heat c = 200 J / Kg / C
The answer in this question is trellis in which define in this statement as the stream pattern which develops on lands underlain by the tilted or folded, alternating hard and soft and sedimentary strata is trellis. Trellis in architecture is an archintectural structure that is usually made from an open framework or lattice of interwoven or intersecting pieces of wood, bamboo or metal.
