<h2>Movement of Continents</h2>
Explanation:
- Alfred Wegener was a German astronomer who proposed the "continental drift" hypothesis in 1910.
- Alfred Wegener was not able to explain the movements of the continent in how and in which way they are moved.
- He failed in an attempt to explain with the use of tides made the theory undefinable fully.
- Also, the major problem with Wegener's theory of Continental Drift was that there was no proper explanation of a mechanism.
Answer:
R (120) = 940Ω
Explanation:
The variation in resistance with temperature is linear in metals
ΔR (T) = R₀ α ΔT
where α is the coefficient of variation of resistance with temperature, in this case α = -0,0005 / ºC
let's calculate
ΔR = 1000 (-0,0005) (120-0)
ΔR = -60
Ω
ΔR = R (120) + R (0) = -60
R (120) = -60 + R (0)
R (120) = -60 + 1000
R (120) = 940Ω
