HELP ME PLES
PERIOD, FREQUENCY OR AMPLITUDE
1. Doesn't change period
2. More of this means more energy
3. Increases as a pendulum swings back and forth faster
4. Measured in cycles per second
5. Measured in meters or centimeters
6. This is decreases with smaller swing
7. If the frequency increases, this decreases
8. Measured in Hertz
9. Measured in seconds
10. if it swings back and forth slower, this decrease
11. As it dampens, this decreases
Answer:
The jar of chermical contains 66g of Zinc.
Step-by-step explanation:
The ratio of Zinc to Copper is 3 : 13
A jar of the chemical contains 286g of copper.
Let the mass of the Zinc be xg.
13/3 = 286/x
x = 3A286/13= 66g
So the jar of chemical contains 66g of Zinc.
1) <span>Pairs A(2, 5), B(6, 5), and C(6, 1)
point D
Dx=Cx-(Bx-Ax)=(6-(6-2))=2
Dy=Cy=1
</span>the coordinates of vertex D is (2,1)
2) Pairs <span>A(2, 3), B(7, 3), and C(7, -2)
</span>point D
Dx=Cx-(Bx-Ax)=(7-(7-2))=2
Dy=Cy=-2
the coordinates of vertex D is (2,-2)
3) Pairs <span>A(-5, -1), B(1, -1), and C(1, -5)
</span>point D
Dx=Cx-(Bx-Ax)=(1-(1+5))=-5
Dy=Cy=-5
the coordinates of vertex D is (-5,-5)
4) Pairs <span>A(-1, 4), B(7, 4), and C(7, -1)
</span>point D
Dx=Cx-(Bx-Ax)=(7-(7+1))=-1
Dy=Cy=-1
the coordinates of vertex D is (-1,-1)
