Answer:
1020 km
Explanation:
A complete rotation of the wheel equals a distance of 1 circumference.
The circumference is
where <em>d</em> is the diameter of the wheel.
300,000 rotations =
In kilometers, this is = 1017876/1000 km = 1020 km

<h3>Further explanation </h3>In Newton's law, it is stated that if the resultant force acting on an object of magnitude is zero, it can be formulated :
then the object tends to defend itself from its state. So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called<em> inertia </em>
The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.
In objects with mass m that move translatively, the object will maintain its linear velocity
When we are in a vehicle that moves forward, then we will still maintain a state of forwarding motion. If our vehicle stops suddenly, then we keep moving forward so we will be pushed forward. From this point, the use of a safety belt serves to hold back our movements so that there are no fatal accidents or collisions.

The De broglie wavelength of a thermal neutron at room temperature 300K = 1.5 × A°
<h3>How is the De broglie wavelength of a thermal neutron at room temperature calculated?</h3>
Temperature, T = 300K
Momentum, p = mv
Therefore v = p/m
Energy, E= 1/2 m( p/m) ²
Boltzman Energy= 3/2 KT
3/2KT = 1/2 m(p/m)²
Therefore p =
According to De broglie hypothesis, P = h ÷ λ
Therefore, λ = h ÷
= 6.6× ÷
= 0.15 ×
Therefore the De broglie wavelength of a thermal neutron at room temperature 300K = 1.5 × A°
