Answer:
Part a)
Part b)
Explanation:
Part a)
change in the energy due to decay of photon is given as
here we know that
now we have
Part b)
While electron return to its ground state it will emit a photon of energy 2/3rd of the total energy
so we have
now to find the wavelength we have
Answer: Category 6 cable
Explanation:
Category 6 cable also called Cat 6 is a standard form of twisted cable pair that is used in Ethernet as well as in other physical network layers that is compatible with the category 5/5e and Cat 3 standard backwards.
Cat 6 has a 500MHZ with better alien crosstalk feature which permits 10 GBASE - 1 to be run at 100 meters maximum which is the same distance at which other Ethernet variants are run.
Cat 6 cable is used in cabling infrastructure such as 10BASE-T (Ethernet) 100BASE-TX (fast ethernet) etc.
The average velocity of the jet during the diversion is 518.75 m/s.
<h3>
Displacement of the pilot</h3>
The displacement of the pilot from the starting position is calculated as follows;
d² = 20² + 60² - 2(20)(60) x cos(θ)
where;
- θ is the angle between 20 km and 60 km leg of triangle formed from the motion.
θ = (90 - 38) + (90 - 55) = 87⁰
d² = 20² + 60² - 2(20)(60) x cos(87)
d² = 3874.39
d = 62.25 km
<h3>Average velocity of the pilot</h3>
V = total displacement/total time
where;
- time = 2mins = 0.033 hour
V = (62.25 km)/(0.033 hr)
V = 1,867.5 km/hr = 518.75 m/s
Thus, the average velocity of the jet during the diversion is 518.75 m/s.

Answer:
<em>The y component of his displacement is 11.22 meters</em>
Explanation:
<u>Components of the displacement</u>
The displacement is a vector because it has a magnitude and a direction. Let's suppose a displacement has a magnitude r and a direction θ, measured with respect to the positive x-direction. The horizontal component of the displacement is calculated by:
The vertical component is calculated by:
The hiker has a displacement with magnitude r = 20.51 m at an angle of 33.16 degrees. Substituting in the above equation:
The y component of his displacement is 11.22 meters
