The amount of energy needed is 2093 J
Explanation:
The amount of energy needed to increase the temperature of a substance by  is given by the equation
 is given by the equation

where
m is the mass of the substance
C is its specific heat capacity
 is the increase in temperature
 is the increase in temperature
For the water in this problem, we have
m = 50.0 g = 0.050 kg
 (specific heat capacity of water)
 (specific heat capacity of water)

Therefore, the amount of energy needed is

Answer:
dsin∅ = m×
λ
so, dsin∅red = 3(670nm)
also, dsin∅? =5λ?
however ,if they overlap then dsin∅red = dsin∅?
3(670nm) /5 =402nm
∴λ = 402nm

Explanation: Newton's first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion.
 
        
             
        
        
        
This is sort of simple.  2 grams of X can combine with 4 grams of Y to form XY.  Y is 2 times the amount of grams in X.  So if there are 11 grams of X there are 22 grams of Y to form XY.  Or you could take 11 divided by 2 is 5.5 and then multiply 4 by 5.5 to get 22.  If this is wrong please tell me I would be very happy to know.
