<u>Answer</u>
Chemical energy in to thermal energy
<u>Explanation</u>
When acetylene fuel is burning in presence of oxygen, we have chemical process taking place. The torch is used to heat metal to its kindling temperature in oxy-fuel cutting. The steam of gas is then trained on the metal burning it into a metal oxide that flows out of the spout.
So the energy transformation represents this process is <em>Chemical energy into thermal energy </em>
The volume of rain that fells in the field is simply given by the area of the field, which is
multiplied by the height of rain that fell, which is
Therefore, the volume is
Answer:
0 1 2 3 4 . because the particle moved with a constant acceleration
Answer:
Explanation:
Speed of car =22.5miles/hr
U=22.5miles/hour
Applied brake and come to rest
Final velocity, =0
t, =2sec
Given that,
Speed=distance /time
Then,
Distance, =speed, ×time
Converting mile/hour to m/s
Given that
Use: 1 mile= 1600 m, 1 h= 3600s
22.5miles/hour × 1600m/mile × 1hour/3600s
Therefore, 22.5mile/hour=10m/s
Using speed =10m/s
Distance =speed ×time
Distance=10×2
Distance, =20m
The distance travelled before coming to rest is 20m.
