Answer:
velocity = 29925×10⁶ m/s
Explanation:
Given data:
Frequency = 35 MHz
Wavelength = 855 m
Velocity = ?
Solution:
MHz to Hz
35×10⁶ Hz
Formula:
<em>velocity = Wavelength × Frequency</em>
velocity = 855 m × 35×10⁶ Hz
velocity = 29925×10⁶ m/s
Hz = s⁻¹
The model represents Photosynthesis. Light, carbon dioxide, and water are the reactants. The products will be Sugar and Oxygen. Photosynthesis releases oxygen and glucose. Which is the energy that living things need to survive.
CaCl2 has a stronger ionic bond than KCl because Ca+2 is smaller than K+ in size.
<h3>What is the working of ionic bonds ?</h3>
A stable link formed by the complete transfer of the valence electron is known as an ionic bond. This kind of interaction results in the formation of positive ions, also known as cations, and negative ions, also known as anions.
- This kind of interaction is exemplified by the ionic bond in sodium chloride, a salt. The sodium valence electron is transferred to the outer electron shell of chloride. Ionic molecules form the basis of ionic compounds.
- The three types of bonds that frequently develop are covalent bonds between nonmetals, ionic bonds between metals and nonmetals, and metallic connections between metals.

Q(heat)= MC delta T
M=mass
c= specific heat capacity
delta T= change in temperature
M=density x volume which is = 1700ml x 1.0g/ml =1700g
change in temperature= 373k-295k=78 K
specific heat capacity for water is 4.186 j/g
heat is therefore= 1700g x 4.186j/g x 78k=555063.6j or 555.0636Kj
Atoms is the correct answer
