<u>Answer:</u>

<u><em>Rolling friction</em></u><em> occurs when a object rolls overs a surface.</em>

<u>Explanation:</u>

Friction is the resisting force which occurs during contact of two objects leading to preventing its motion. The loss due to friction is released in the form of heat energy.

When two objects come in contact with each other for any kind of motion, the electromagnetic attraction of the charges exhibited by the two objects leads to resisting the motion of the object with the release of heat energy.

In this case, when a object is rolling over a surface, the roughness of the surface will contribute to the friction between the surface and the rolling object leading to variation of the speed of the rolling object. This kind of friction experienced by a rolling object is termed as rolling friction.

A student drops an egg from the roof of their house onto a trampoline. The egg feels a change in momentum of 2.2 kg^ * m/s in 1.

geniusboy [140]

Answer:

F = m a = m v / t where v is the change in velocity in time t

F = p / t since m v is equal to p

F = 2.2 (kg m / s) / 1.1 s = 2 kg-m / s^2 = 2 N

Or you can use the impulse equation

Baryon number is +1 on the left side of the equation, 0 on the

right side. Baryon number is not conserved.

<h3>How do you determine whether a baryon number is conserved?</h3>

According to the law of conservation of baryon number, the sum of the baryon numbers of all incoming particles equals the sum of the baryon numbers of all particles produced by the reaction. Energy, and so on, are conserved even if the incoming proton has sufficient energy and charge.

<h3>What is Baryon Number</h3>

In particle physics, the baryon number denotes which particles are baryons and which particles are not. Each baryon has a baryon number of 1, and each antibaryon has a baryon number of -1. Other non-baryonic particles have a baryon number of 0. Since there are exotic hadrons like pentaquarks and tetraquarks, there is a general definition of baryon number as:

B=1/3( $n_{q} -n_q^{-} }$ )

where $n_{q}$ represents the number of quarks and nq represents the number of antiquarks.
