alisha [4.7K]

Answer:

Momentum

Explanation:

Heisenberg uncertainty principle says it is <em>uncertain to find the momentum and position of a particle at the same time. there must be some uncertainty.</em>

\Delta X.\Delta P\geq \hbar.

It means decreasing the position value will increase the momentum value while decreasing the momentum value will increase the position value.

I hope it works for you

Thank you.

Two bicycle tires are set rolling with the same initial speed of 4.00 m/s along a long, straight road, and the distance each tra
77julia77 [94]

Answer:

The coefficient of rolling friction for the tire under low pressure is 0.0342.

Explanation:

Two bicycle tires are set rolling with the same initial speed of 4.00 m/s

Final speed of both the bicycle, speed is reduced by half is measured, v = 2 m/s.

Here,

u_kmg = ma\\\\a=\mu g

Using third equation of motion as :

v^2-u^2=2as\\\\v^2-u^2=2\mu gs\\\\\mu =\dfrac{v^2-u^2}{2gs}\\\\\mu =\dfrac{4^2-2^2}{2\times 9.8\times 17.9}\\\\\mu=0.0342

So, the coefficient of rolling friction for the tire under low pressure is 0.0342.
