Answer:
Latent heat, along with birds, ride those rising columns of air. This brings up a third and the ultimate mechanism by which the Earth's heat escapes into space, which is electromagnetic radiation. Every object, including the Earth's surface, absorbs and radiates heat electromagnetically

I LITERALLY JUST COPIED AND PASTED THIS FROM GOOGLE..i dont understand anything from it since im not on this topic but hope this help a little....i got it from google ..not my own work 
 
        
             
        
        
        
Answer:
1.2826 x 10^-13 m 
Explanation:

Here, k be the kinetic energy and m be the mass
K = 50 KeV = 50 x 1.6 x 10^-16 J = 80 x 10^-16 J
m = 1.67 x 10^-27 kg 

λ = 1.2826 x 10^-13 m 
 
        
             
        
        
        
Answer:
nothing travels faster than light

You’ll always see lightning before you hear it, because typically lightning will be a mile away, two miles away.
 
        
             
        
        
        
Answer: amplitude
Explanation: This describes the maximum amount of the displacement of a particle from it rest position. Usually, it is measured in metres 
Since we are considering AM which is amplitude modulation, a technique used in electronic communication, most commonly for broadcasting information through a radio carrier wave. In amplitude modulation, the amplitude (signal strength) of the carrier wave is diversified in proportion to that of the message signal being broadcasted.
