An object of unknown mass m is hung from a vertical spring of unknown spring constant k, and the object is observed to be at rest when the spring has stretched by 17 cm . the object is then given a slight push upward and executes shm. determine period t of this oscillation

Period is 0.827s

Explanation:

Given distance x= 17cm = 0.17m

We recall that Force F = k× x= k × 0.17m

We recall that F = M × g = M × 9.8

Equating both equations:

kx = mg

=> k/m = g/x

= 9.8/0.17 = 57.647

We also recall that ω = √(k/m)= 2πf = 2π/T.

√(k/m) = 7.593

=> T = 2π/7.593

Period T = 0.827s

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
