Answer:As an object speeds up, the total energy increases / decreases / remains the same. As an object slows down, the total energy increases / decreases / remains the same.
Explanation:
Answer:
B) Periodic Motion
Explanation:
When a pendulum is friction-less, i.e there are no damping forces acting on it, its motion will be periodic, i.e it will bob up and down going from potential energy to kinetic energy and back. Thus, the motion of the pendulum can be best described by the term "period motion", hence choice B.
If however, forces do act on the pendulum, and if they acts as to damp the pendulum, it will oscillate less and less as time goes by, and eventually come to a stop (in the real world this damping force is usually air resistance ). And if the force acts in such a way that it increases the oscillations, the pendulum will swing higher and higher, and the system will go haywire! :)
Oil, grease and dry lubricants
Solution :
Given :
L = 1 in
d = 0.75 in
D = 1 in
Fillet radius, r = 0.063 in

We know that :





MPa
= 130 MPa
Therefore, the stress concentration factor is :

= 1.157922
Explanation:
P, Primary, or Compressional waves travel the fastest (~6 km/sec in the upper crust). They cause the matter to oscillate forward and backward, parallel to the motion of the seismic wavefront. P waves push (compress) and pull (dilate) the rock that they pass through.
