Answer:
(of the moon) have a progressively smaller part of its visible surface illuminated, so that it appears to decrease in size.
Explanation:
The types of chemical reactions are as follows:
- Combination reactions
- Decomposition reactions
- Double decomposition
- Thermal dissociation
- Redox reactions
<h3>What the are the types of reactions?</h3>
Chemical reactions are changes in which new substances are formed.
The types of chemical reactions are as follows:
- Combination reactions - these are reactions in which two or more substances combine to form a single compound
- Decomposition reactions - these are reactions in which a larger compound splits into smaller substances
- Displacement reactions - these are reactions in which one element or radical replaces another in a compound
- Double decomposition - these are reactions in which two substances exchange their radicals to form new compounds.
- Thermal dissociation - these reactions involves heating compounds to split them into smaller substances.
- Redox reactions - these are reactions in which oxidation and reduction reactions occur simultaneously.
In conclusion, chemical reactions produce new substances.

Answer:
angular range is ( 0.681 rad , 0.35 rad )
Explanation:
given data
wavelength λ = 380 nm = 380 × 
m
wavelength λ = 700 nm = 700 × m
to find out
angular range of the first-order
solution
we will apply here slit experiment equation that is
d sinθ = m λ ...........1
here m is 1 for single slit and d is = 
so put here value in equation 1 for 380 nm
we get
d sinθ = m λ
sinθ = 1 × 380 ×
θ = 0.35 rad
and for 700 nm
we get
d sinθ = m λ
sinθ = 1 × 700 ×
θ = 0.681 rad
so angular range is ( 0.681 rad , 0.35 rad )
Answer:
The required work done by the resistive force = -22.3 kJ
Explanation:
We understand that the amount of work done for a force F and displacements is provided as the product of force multiplied by displacement, which can be represented as W = F.S
Now, when the cyclist travels east and returns west, the force and displacement directions will be opposite and they make an angle 180 degrees apart.
∴
W = -2 × 7.00 × 1590
W = -22260 J
W = -22.3 kJ
