Answer:
bueno lo siguiente es que yo no sé inglés
Given: Mass m = 290 Kg; Height h = 7 m
Required: Work = ?
Formula: Work = Force x distance but, Force F = mg
W= fd
W = mgh
W= (290 Kg)(9.8 m/s²)(7 m)
W = 19,894 Kg.m²/s²
W = 19,894 J

Answer:
No they are not the same.
Explanation:
S=d/t Speed equals distance divided by time. Leah's wave took 10 seconds, and the distance was 6 meters.
6/10=.6
Betty's wave took 10 seconds, but the distance was 60 meters this time.
60/10=6
We know that 6 and .6 are not the same numbers, so we can see that the waves aren't the same.
I hope this helps!!
