A compound. For example, hydrogen and oxygen atoms form water.
The absorption spectrum would have all the wavelengths of the light source but would have black lines where the two red and one orange lines were in the emission spectrum
Answer:
When elements bond together or when bonds of compounds are broken and form a new substance
Explanation:
= Heat released to cold reservoir
= Heat released to hot reservoir
= maximum amount of work
= temperature of cold reservoir
= temperature of hot reservoir
we know that

eq-1
maximum work is given as
=
- 
using eq-1
=
- 
Answer:
355 m/s
Explanation:
Distance = 605 km
Initial speed =
= 284 m/s
Final velocity =
= 426 m/s
Average speed = ?
There is two method two find average speed. In first method, using 3rd equation of motion, we find acceleration.

Then using first equation of motion, we find time

Then using the formula of average velocity, we find average velocity

Second method is very simple


355 m/s
