Which of the following is most accurate statement about both light and sound waves ? A. Light and sound waves cannot travel through water.
B. Both light and sound waves travel to Earth from the Sun.
C. Light and sound waves both travel at the same speed.
D. The speed of waves can change depending on the medium.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

ingenuity says that the answer is 2.7 m.

98.4 m

explanation:

let s = distance up the plane  

then by conservation of energy  

1/2m(18.3)^2 = mg s sin(10)  

(18.3)^2 = 2g s sin(10)  

s = (18.3)^2/2gsin(10)  

= 98.39564526  

= 98.4 m
