A student studies how an object's mass and speed are related to its kinetic energy. The table shows the results for one part of the investigation.
? Kinetic energy (J)
1 100
2200
3 300
Which two terms are most likely to be used to label the data in the first
column?
A. Mass
O
B. (m/s)
C. (kg)
O
D. Speed

A and D.

Explanation:

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
