Answer: the particles are more orderly in region 1
Explanation: region 1 is when the substance is a solid and as it is heated the particles move further apart and have more kinetic energy.
Answer:
The particles are more orderly in region 1.
Explanation:
Answer: 345600 J
Explanation: solution attached
KE= 1/2 mv²
4.80 seconds
The velocity of sound is obtained from;
V= 2d/t
Where;
V= velocity of sound = 329.2 ms-1
d= distance from the wall = 790.5 m
t= time = the unknown
t= 2d/V
t= 2 × 790.5/ 329.2
t= 4.80 seconds
5.7 kilometers is equal to 3.5418157957528034 miles
