1. 24.6 = v₁ + 2.22 x 5.80
   v₁ = 11.7 m/s

2. volts

3. negative     positive

4. D = m/V
   V = 1.59 cm³

5. kPa or PSI

6. voltage, current, & resistance

7. V = IR

8. amps     I

9. V = IR
   multiply V = 3.0 volts

10. Vector diagram, ask for assistance

11. Vector diagram, ask for assistance if needed

12. can't answer for you

13. force of attraction between the Earth and any object
    pulling force down towards the Earth

14. A graph slope is 2.0 cm/s

15. 1. 54
    2. 8.27
    3. 7
    4. d = 9
    5. F = 3
    6. m = ½
    7. factor equation (x + 4)(x - 2) = 0 giving x = -4 & x = 2

16. In sound particles vibrate transmitting the energy, in light electromagnetic waves transmit energy. Sound hear with ears, Light see with eyes
    both are wave and both transmit energy.
