The second hand on a clock has a length of .30m. What distance does the tip of the second hand sweep through in one minute and 30 seconds?
a.) 2.8m
b.) .45m
c.) 1.8m
d.) 5.0m
Please explain and show all work

Answer #1
The second hand completes one revolution in 60 seconds. From
this we find the angular speed of the second hand and use that to
find the angular displacement. Use the angular displacement and
radius, which is the length of the second hand, to find the
distance travelled as shown below

(a) Find parametric equations that describe the circular path of
the tip of a 15-inch second hand of a clock that completes one
revolution in 60 seconds. (Assume that (x,y) denotes the position
of the object relative to the origin at the center of the
circle)
(b) Use the arc length formula to compute the distance traveled
by the tip of the second hand during the first 24 seconds of its
revolution.

If two wires carry current next to each other, they will exert a
force on each other. The force is caused by magnetic fields. One
current creates a magnetic field, and this field exerts a force on
the other current. The magnitude of the field created by a long,
straight current-carrying wire is given by Equation 1 below;
B= (μ0i)/(2πr)
where i is the current and r is the distance from the wire. The
magnitude of the force exerted on...

Objectives:
1. To introduce pointer
variables and their relationship with arrays
2. To introduce the
dereferencing operator
3. To introduce the
concept of dynamic memory allocation
A distinction must always be made between a memory location’s
address and the data stored at that location. In this lab, we will
look at addresses of variables and at special variables, called
pointers, which hold these addresses.
The address of a variable is given by...
