Answer:
The ratio of kinetic energies of 5 kg object to 20 kg object is 1:1.
Explanation:
Kinetic energy is defined as energy possessed by an object due to its motion.It is calculated by:
Kinetic energy of the 5 kg object.
Mass of object,m = 5 kg
Velocity of an object = v
Kinetic energy of the 20 kg object.
Mass of object,m' = 20 kg
Velocity of an object = v'
The ratio of the kinetic energy of the 5 kilogram object to the kinetic energy of the 20-kilogram object:
Given that, v = 2v'
The ratio of kinetic energies of 5 kg object to 20 kg object is 1:1.

The line width is calculated as 121.6nm
Data;
- Wave length = 393.3nm
- T1 = 3000k
- T2 = 12,000K
<h3>Rydberg's Formula</h3>
This is used to calculate the wavelength of an electron when it moves from one state to another.
For Lyman series, n = 1
The energy difference in the two state transitioning are
= ∞
The formula is given thus;
R = Rydberg's constant
Z = atomic number
Since the excited electron dropped from the 1st state to the ground state, the finest line of Lyman series would be

Answer:
The ax versus t graph stays in the range of 2.5 to 3 m/s2 for the first 2 seconds or so, and then it drops quickly to just below 0 m/s2. This corresponds well with the slope of the vx graph: relatively constant positive slope for the first 2.5 seconds, and then zero (and even negative) slope afterwards.
