Answer: When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
 
        
             
        
        
        
Given Information:  
Elapsed time = t = 6 seconds
Required Information: 
Distance = d = ?
Answer:
Distance = d = 2.058 km
Explanation:
We know that the speed of sound in the air is given by
v = 343 m/s
The relation between distance, speed and time is given by
distance = speed*time
substituting the given values yields,
distance = 343*6
distance = 2058 m
There are 1000 meters in 1 km so
d = 2058/1000
d = 2.058 km
Therefore, the storm is about 2.058 km away when elapse time between the lightning and the thunderclap is 6 seconds.
 
        
             
        
        
        
Answer:
0.906 N
Explanation:
Formula for magnetic force acting on current carrying cable:

Where I = 345A is the current in the wire, B =  is the magnetic magnitude generated by Earth. L = 46.9 m is the cable length.
 is the magnetic magnitude generated by Earth. L = 46.9 m is the cable length.  is the angle between vector B and cable direction.
 is the angle between vector B and cable direction.
