(I)
firstly , we will find maximum and minimum y-value
we can see that
maximum value is 5
minimum value is -5
so, we can find amplitude
![A=\frac{5-(-5)}{2}](https://tex.z-dn.net/?f=%20A%3D%5Cfrac%7B5-%28-5%29%7D%7B2%7D%20%20)
..........Answer
(II)
we know that
wave length is the length of one wave
we can see that from B to F , there is one wave
and we are given it's length as 20cm
so, wavelength is 20cm......Answer
(III)
we know that
![velocity=wavelength*frquency](https://tex.z-dn.net/?f=%20velocity%3Dwavelength%2Afrquency%20)
we are given
frequency =100hz
wavelength =20cm
now, we can find velocity
![velocity=20*100cm/sec](https://tex.z-dn.net/?f=%20velocity%3D20%2A100cm%2Fsec%20)

Answer:
the value of a plus three
Step-by-step explanation:
It's not possible nothing but 1 times 5 is the only thing that multiplies to 5 and 1+5 doesn't equal 4
To solve this problem, all we have to do is to convert
ounce into grams. We know that:
1 ounce = 28.3495 gram
Therefore converting this into gram:
weight = 8 ounce * (28.3495 gram / 1 ounce)
<span>weight in grams = 226.796 grams</span>
