Cube A has more thermal energy than cube B.
Explanation:
It is obvious that cube A has gained more thermal energy compared to cube B. 
From the description of the experiment, both cubes had the same temperature which is 50°C. Temperature is the degree of hotness or coldness of a body. 
Thermal energy is a form of energy expressed as heat in a body. 
Cube A has a higher volume because it has gained more thermal energy than Cube B. 
Thermal energy increases the rate of vibration of atoms in the crystal lattice of the solid. The more the thermal energy, the more the vibration. This is  why Cube A has expanded so much and changed volume.

Answer:
Options: 1, 3, 5, 7, 8
Explanation:
In steady state at the point when the current at each point in the circuit is  
consistent (doesn't change with time).  
-  In numerous viable circuits, the steady state is accomplished in a brief period of time.
- 
In the steady state, the charge (or current) streaming into any point in the circuit needs to equivalent the charge (or current) streaming out which is  Kirchhoff's Node or Current law.
 
        
             
        
        
        
11,000 m = 11 km
11 km/s over 380,000km
380,000 / 11 = 34545.4 seconds
34545.4 / 60 = 575.7 minutes
        
             
        
        
        
Answer:
C. Beats
Explanation:
When waves are interfering with each other, the sound is louder in some places and softer in others. As a result, we hear pulses or beats in the sound.
 
        
             
        
        
        
Answer: North of west
 North of west
Explanation:
Given
40,000-ton luxury line traveling 20 knots towards west and 
60,000 ton freighter traveling towards North with 10 knots
suppose v is the common velocity after collision 
conserving momentum in west direction

suppose the final velocity makes \theta angle with x axis 

Conserving Momentum in North direction


divide 1 and 2


so search in the area  North of west to find the ship
 North of west to find the ship
