The flow of Direct current (DC) is constant and flows in one direction. Most digital electronics make use of DC. Alternating current (AC) periodically flows in reverse and is mostly used to deliver power to houses, buildings and the like. With that alone, you can already rule out A, C and D.
The answer would then be B. constant, periodically reversing.
Answer:
the tension produce by the bird in the wire is 610.3 N.
Explanation:
given information:
mass of the bird, m = 1 kg
distance of two telephone pole, L = 50 m
wire sag, y = 0.2
the tension of the wire can be calculate by the following equation
tan θ = y/(L/2)
= 0.2/(50/2)
= 0.2/25
thus
θ = arc tan (0.2/25)
= 0.46°
according to Newton's first law
ΣF = 0, vertical direction
T sin θ + T sin θ - mg = 0
2 T sin θ = m g
T = mg/2 sinθ
= 1 x 9.8/(2 sin 0.46)
= 610.3 N

brainliest plz
The direction the telescope may be heading ummm honestly I don’t know the answer to that
Answer: It leads to a front. A front is.., I don't know how to explain it, so I'll add a picture. Fronts are made out of clouds and usually bring rain. So the answer is C: The formation of clouds and rain.
