Answer:
Spring constant, K = 415.9 N/m
Explanation:
The period of vibration of a spring, T, is given by:
T = 2√m/K
Where m = mass of the body in kg, K = spring constant or force constant or elastic constant or stiffness in Nm-1
Making K the subject of the expression,
K = m(2)2/(T)2
K = 4m()2/(T)2
Where m = 0.38kg, = 3.14285714286, T = 0.19s
K = 4 x 0.38 (3.14285714286)2 / (0.19)2
K = 4 x 0.38 x 9.87755102043 / 0.0361
K = 15.0138775511 / 0.0361
K = 415.9 Nm-1
Ice wedging, pressure release, plant root growth, and abrasion can all cause mechanical weathering. in the cracks and pores of rocks, the force of its expansion is strong enough to split the rocks apart. ... This release of pressure causes the rock to expand. As the rock expands, cracks form in it, leading to exfoliation.
African Americans are stronger as a result.
African Americans are more hopeful of the future.
African Americans are better off than other black people around the world.
