Thats kind of a weird question. i believe its B, though.
i hope this helps
Its b.functional paragraph because writers use this for interest presents and special effects
<span>A baseball is thrown vertically upward and feels no air resistance. As it is rising </span>its momentum is not conserved, but its mechanical energy is conserved.
a)
Amplitude of wave is given as maximum displacement from mean position
So here amplitude is 1.25 cm
b)
Wavelength is the length of the wave that it travels in one time period
From graph we can say the wavelength is given as 3cm
PART C)
Time period of wave is the time after which it repeats its shape
Speed of the wave = 21 cm/s
time period = wavelength / speed
Now frequency is
PART D)
Time period = \frac{1}{f}[/tex]
Answer:
Explanation:
This is a displacement vector since it is defined in terms of distance (meters, to be exact). The way you find the y-component is
which says that you multiply the magnitude of the vector (its length) by the sin of the direction (the angle):
and get
12.1 m
