Which of the following is NOT a reason why two different sources
may have different beta values?
A. The market proxy that was used for calculation may have been
the S&P500 instead of the Nasdaq
B. 2 years of data may have been used to calculate beta instead
of 5 years.
C. Weekly returns may have been used instead of monthly
returns
D. Beta is a measure of risk.
A plane mirror is placed 20° above the horizontal on
the corner of a room and another plane mirror is placed at the
vertical wall. Determine the angle of reflection made by the mirror
on the wall.
In the car there is a circular tray that can rotate in
horizontal plane above the seat. Let the car start moving in
straight direction with acceleration of 0.5 m/s^2 relative to the
ground. The tray on the seat starts to rotate simultaneously with
the angular velocity ω = 2πt. At this moment, a mass of m = 0.01 kg
the spider starts moving in the radial direction outward from the
center of the tray with V = 0.1 m...
An inclined plane is sliding, and accelerating, on a horizontal
frictionless surface. There is a block at rest on the sloping
surface, held in place by static friction through the horizontal
acceleration of the system. The coefficient of static friction
between the block and the inclined plane is 0.615. The slope of the
incline plane is 40.5 degrees with respect to the horizontal.
What is minimum acceleration of the inclined plane for the square
block not to slide? What is...
An inclined plane is sliding, and accelerating, on a horizontal

surface, held in place by a static friction through the horizontal
acceleration of the system. the coefficient of static friction
between the block and the inclined plane is 0.615. the slope of the

a) What is the minumum acceleration of the inclined plane for
the square block not to...
A block is placed on a plane inclined at 35 degrees
relative to the horizontal. If the bloc k slides down the plane
with an acceleration of magnitude g/3, determine the coefficient of
the kinetic friction between the block and plane.
Describe the reason why the scientific method is the basis for
scientific discovery and the role that it plays in creating sound
and reliable theories.

which is the reason why the equation is reached: dU = FcosΘds to
describe the work done by a force.
Include descriptive schemes.
Write when the work is positive, negative or null depending on
the angle between the force component and the displacement.
What is the unit of measurement of labor (U) in the
international system and in the imperial system?
What is the reason for the seasons? Explain fully why different
hemispheres experience opposite temperatures at some times of the
year and similar temperatures at others. Identify the months when
these events occur.
