If the sun were to burn out, it would take humans just over 8 minutes to realize because light from the sun takes just over 8 minutes to reach earth. Tommy was 3 years old when his dad showed him a particular star that was estimated to be 18 light years
away from earth. If the star burned out immediately after Tommy was showed it, how old would Tommy be before he realized the
star was gone?
A)
21 years old
B)
18 years old
9 years old
D)
6 years old

To protect all four receptacles on a branch circuit that surrounds a swimming pool, you would install which of the following configurations? a. gfci feed-through receptacle at the end of the load's circuit b. gfci-terminated receptacle at the beginning of the load's circuit c. gfci feed-through receptacle at the beginning of the load's circuit and the other receptacles connected to the load side of that receptacle d. gfci-terminated receptacle at each end of the load's circuit

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
