Answer:
A u = 0.36c B u = 0.961c
Explanation:
In special relativity the transformation of velocities is carried out using the Lorentz equations, if the movement in the x direction remains
u ’= (u-v) / (1- uv / c²)
Where u’ is the speed with respect to the mobile system, in this case the initial nucleus of uranium, u the speed with respect to the fixed system (the observer in the laboratory) and v the speed of the mobile system with respect to the laboratory
The data give is u ’= 0.43c and the initial core velocity v = 0.94c
Let's clear the speed with respect to the observer (u)
u’ (1- u v / c²) = u -v
u + u ’uv / c² = v - u’
u (1 + u ’v / c²) = v - u’
u = (v-u ’) / (1+ u’ v / c²)
Let's calculate
u = (0.94 c - 0.43c) / (1+ 0.43c 0.94 c / c²)
u = 0.51c / (1 + 0.4042)
u = 0.36c
We repeat the calculation for the other piece
In this case u ’= - 0.35c
We calculate
u = (0.94c + 0.35c) / (1 - 0.35c 0.94c / c²)
u = 1.29c / (1- 0.329)
u = 0.961c

The correct option would be A. solar.
We also use solar energy to produce electricity.
Have A Nice Day ❤

Verrrrrry interesting !
Acceleration = (change in speed) / (time for the change)
The car's acceleration is (60 mph) / (3.8 sec) = (60/3.8) mile/hr-sec .
Final speed = (original speed) + (acceleration · time)
= (30 mi/hr) + (60/3.8 mi/hr-sec)·(6 sec)
= (30)mi/hr + (360 / 3.8)mi/hr
= 124.7 mph .
B is false.
not all carbon atoms have 6 neutrons. Carbon 13 for example has 7 neutrons
Acceleration is equal to velocity final minus velocity initial divided by time. 6m/s minus 4m/s divided by 5 seconds is 0.4m/s^2.
