Answer:
O A. PQ = SU
Step-by-step explanation:
When two triangles are congruent then by CPCTC,
their corresponding parts ( angles and sides ) must be congruent.
In triangles PQR and STU,
Side PQ, QR and RP are corresponding to the sides ST, TU and US respectively,
Also, angles P, Q and R are corresponding to angles S, T and U respectively.
Here, Δ PQR ≅ Δ STU,
Thus, by the above property,
PQ ≅ ST, QR ≅ TU and RP ≅ US,
∠P ≅ ∠T, ∠Q ≅ ∠T and ∠R ≅ ∠U

Answer:
heat the air
Step-by-step explanation:
Lightning is just a high-intensity amount of electricity. Picture zapping something with electricity: it doesn't get cold, it gets hot.
That's because when a current is passed through something, it has more energy, so the molecules start to vibrate faster and move around much faster than they were before, which causes friction and a buildup of heat.
If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
Wouldn’t it be 60? 60 has both 12 and 15 as factors and is less than 100. 12 x 5 = 60 and 15 x 4 = 60.
