<h2>
The answer got is reasonable.</h2>
Explanation:
We have equation of motion v² = u² + 2as
Initial velocity, u = 300 m/s
Acceleration, a = ?
Final velocity, v = 400 m/s
Displacement,s = 4 km = 4000 m
Substituting
v² = u² + 2as
400² = 300² + 2 x a x 4000
a = 8.75 m/s² = 8.8 m/s²
The acceleration is 8.8 m/s²
The answer got is reasonable.
Answer:
Explanation:
time= distance/speed
20km/ 15km/h
= 1 1/3 hours (4/3 in mixed fraction)
With a partner, describe interactions in this scene, tracing the movement of materials or energy through all four of Earth's spheres if possible. Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere.
Answer:
emission of photon is of maximum wavelength when electron transition is from n = 8 to n = 5
Explanation:
Longest wavelength for the transition means the energy difference in two levels must me minimum
So here we know that the energy of electron in a given level is
now if z = 1 for hydrogen
then Energy of electron for n = 2
Energy of electron for n = 5
Energy of electron for n = 8
Now for least energy difference we can say
So emission of photon is of maximum wavelength when electron transition is from n = 8 to n = 5
