Answer:
m = 12.05 kg
Explanation:
Spring constant in K, N/m
K = 200/10* 100
K = 2000 N/m
Angular Frequency = sqrt (Spring constant / (Mass )
ω = 2 π f
ω = 2π* 2.05 Hz = 12.8805 rad/s
ω^2 = Spring constant / Mass
Mass= Spring constant / ω^2
ω^2 = 165.907 rad^2/s^2
m = 2000 (N/m)/165.907 (rad^2/s^2)
m = 12.05 kg
The three types of stress that act on Earth's rocks are compression, tension and shear. Among all the options that are given in the question, the correct option is option "D". These kind of stress action creates the rocks to break in a natural way. The earth's rocks sometimes collide with one another, pull apart from each other and sometimes slide against each other. Whenever two rocks collide with each other, they create a compression force. When the two rocks of the earth tries to pull away from each other, it creates a tension force. The sliding of two earth's rocks creates a shearing force.
Answer:
or a roller coaster loop, if it were perfectly circular, we would have a minimum speed of vmin=√gR at the top of the loop where g=9.8m/s2 and R is the radius of the 'circle'. However, most roller coaster loops are actually not circular but more elliptical.
Explanation:
Answer:It shows the size of the range of the moisture contents at which the soil remains plastic. In general, the plasticity index depends only on the amount of clay present. It indicates the fineness of the soil and its capacity to change shape without altering its volume.
