When an object is becomes warm its an example of exothermic reaction.
Answer:
Initial Velocity = 0 m/s
Final Velocity = 34.6 m/s
time = 3.5 s
Explanation:
The initial velocity must be zero since, the egg must be at rest initially, before dropping.
<u>Initial Velocity = 0 m/s</u>
Now, for time we use 2nd equation of motion:
h = Vi t + (1/2)gt²
where,
h = Height = 61 m
Vi = Initial Velocity = 0 m/s
g = 9.8 m/s²
t =time = ?
Therefore,
61 m = (0 m/s)(t) + (1/2)(9.8 m/s²)t²
t² = (61 m)(2)/(9.8 m/s²)
t = √(12.45 s²)
<u>t = 3.5 s</u>
Now, for final velocity we will use 1st equation of motion:
Vf = Vi + gt
Vf = 0 m/s + (9.8 m/s²)(3.5 s)
Vf = 34.6 m/s
Answer:
for C-Cl bond 
for O-O bond 
Explanation:
- We have the bond enegy for C-Cl,

- bond enegy for C-Cl,

<u>Now as we know the energy of electromagnetic waves is given by:</u>

here E = BE
<u>Then for C-Cl:</u>


Now wavelength:



<u>For O2:</u>


Now wavelength:
