The period of a pendulum is given by the equation
t = 21
which of the following domains provide a real-
value period?
og 0
o g = 0
og> 0
o 920
done
where l is the length of the string suspending the
pendulum in meters, and g is the acceleration due
to gravity in m/s2

Step-by-step explanation:

Among the options, the most reasonable is g > 0, because the movement of a pendulum depends on gravity, it's the reason of the movement actually, because the gravity is the acceleration of such oscillation.

Moreover, without gravity there weren't any pendulum movement, remember that acceleration refers to the change of velocity, which is what happens in all oscillations of a pendulum. If you think about it, you will realize that a pendulum stops in extreme points, then goes back, this movement tend to be periodical, because the gravity is approximately constant basically.

Therefore the right answer is g > 0.

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
