The first two are always the reactants the products come after so they are last
        
             
        
        
        
Answer:
0.25 m
Explanation:
Electromagnetic waves consist of oscillations of the electric and the magnetic field, oscillating in a plane perpendicular to the direction of motion the wave.
All electromagnetic waves travel in a vacuum always at the same speed, the speed of light, whose value is:
 
Microwave is an example of electromagnetic waves.
The relationship between wavelength and frequency for an electromagnetic wave is:

where
 is the wavelength
 is the wavelength
 is the speed of light
  is the speed of light
f is the frequency
For the microwave in this problem,

So its wavelength is

 
        
             
        
        
        
A lighted candle produces heat however not as much heat as a heater or the sun would.
        
             
        
        
        
For A 53 g ice cube at −30◦C is dropped into a container of water at 0◦C, the amount of water that freezes onto the ice?  is mathematically given as
x = 9.93 g
<h3>What is the amount of water that freezes onto the ice?</h3>
Where
Energy received = energy given out
Generally, the amount of water is mathematically given as
(53)(0.5)(30) = (80)(x)
Therefore
x = (49)(0.5)(16)/(80)
x = 9.93 g
In conclusion, the mass of water
x = 9.93 g
