It is whiplash I hope this is right
Answer: The rock cycle involves the transition of rocks from igneous to sedimentary and metamorphic
The older rock would underlie the younger, recently formed rocks
Explanation:
It has been noted by geologists that most of the oldest rocks on earth are metamorphic, this is because they have been buried to such a depth that temperature and pressure changes them.
These metamorphic rocks could be have been igneous or sedimentary, depending on their mode of formation (solidification of magma or denudation)
Metamorphic rocks can melt partially and find its way to the surface as magma, forming igneous rocks when they cool and solidify.
These igneous rocks can get exposed throught weathering, get eroded away and get deposited on another rock (either igneous, sedimentary or metamorphic) while cementation and compaction makes sure it hardens and consolidates properly
The law of superposition implies that younger rocks overlie the older ones, because they have been formed sequentially
Answer:
B = (4.76 × 10⁻⁷) T
Explanation:
From Biot Savart's law, the magnetic field formula is given as
B = (μ₀I)/(2πr)
B = magnetic field = ?
I = current = 238 mA = 0.238 A
μ₀ = magnetic constant = (4π × 10⁻⁷) H/m
r = 10 cm = 0.1 m
B = [4π × 10⁻⁷ × 0.238)/(2π×0.1)]
B = (4.76 × 10⁻⁷) T
The direction of the magnetic field is in the clockwise direction wrapped around the current-carrying wire.
Hope this Helps!!!
