d) -168,750 J
9 answers
1) c 76cm southwest
2) c 66.4 m
2) c 66.4 m
🍀 is correct on the first two. The other two are:
3) 60 kWh
4) -506,250 J
3) 60 kWh
4) -506,250 J
25) 35,900 km
26) 0.0167
27) the same amount of time
28) 22.3 AU
26) 0.0167
27) the same amount of time
28) 22.3 AU
so im just gonna give yall the answers
