Answer:
The speed, as they crash together, is the same than before the crash, but with opposite directions. In this context, we recur to the collision theory in physics, which says that the amount of movement of each particle before the collision is the same than after the collision, due to the conservation of the amount of movement, which can be described like this: . This expression means that in a isolated environment (which is present in a neutron's collision), the total amount of movement doesn't change.
Therefore, <em>the speed of neutrons is the same before and after the collision</em>. Specifically the number of this speed depends on the experiment.
Answer:
hello your question is incomplete attached below is the missing part
answer : short period oscillations frequency = 0.063 rad / sec
phugoid oscillations natural frequency ( ) = 4.27 rad/sec
Explanation:
first we have to state the general form of the equation
=
where :
comparing the general form with the given equation
= 18.2329
hence the short period oscillation frequency ( ) = 0.063 rad/sec
phugoid oscillations natural frequency ( ) = 4.27 rad/sec
Explanation:
a) Acceleration due to gravity
Here we need to find acceleration due to gravity of Sun,
G = 6.67259 x 10⁻¹¹ N m²/kg²
Mass of sun, M = 1.989 × 10³⁰ kg
Radius of sun, r = 6.957 x 10⁸ m
Substituting,
Acceleration due to gravity on the surface of the Sun = 274.21 m/s²
b) Acceleration due to gravity in earth = 9.81 m/s²
Ratio of gravity = 274.21/9.81 = 27.95
Weight = mg
Factor of increase in weight = 27.95
