56 rpm = 56 rotations per 60 secs. ω = 2π/T (from http://blade3891.tripod.com/id9.html)
ω is the angular velocity.
T is the period. This is the number of seconds it takes to complete one rotation. Since it takes 60 seconds to complete 56 rotations, it takes 60/56 seconds to complete one rotation.
T = 60/56.
so ω = 2π/(60/56) = roughly 5.86 radians per second
What else can I help you with?
Does a particle moving along a line that passes through the origin has zero angular momentum about that origin?
No, the particle's angular momentum depends on both its linear momentum and its distance from the origin. If the particle is moving along a line passing through the origin, its angular momentum will not necessarily be zero unless its linear momentum is also zero.
If a particle moves in a straight line is its angular momentum zero with respect to any arbitary acis?
Yes, for a particle moving in a straight line, its angular momentum is zero with respect to any arbitrary axis. This is because angular momentum is defined as the cross product of the position vector and momentum vector of the particle, and since they lie along the same line for straight-line motion, the cross product will result in zero.
What will be the ratio of the distance covered t the displacement of a particle moved along a semi-circle of radius r?
The ratio of the distance covered to the displacement of a particle moved along a semi-circle of radius r is π. This is because the distance covered around the semi-circle is the circumference (2πr), while the displacement is the diameter of the circle (2r). The ratio is therefore (2πr) / (2r) = π.
What is the direction of angular momentum?
Angular momentum of a rotating particle is defined as the moment of the linear momentum of the particle about that axis.It is perpendicular to the plane of rotation and parallel to the axis of rotation.
What is the expression for the l2 operator in spherical coordinates and how does it affect the quantum state of a particle in a spherically symmetric potential?
The expression for the (l2) operator in spherical coordinates is ( -hbar2 left( frac1sintheta fracpartialpartialtheta left( sintheta fracpartialpartialtheta right) frac1sin2theta fracpartial2partialphi2 right) ). This operator measures the square of the angular momentum of a particle in a spherically symmetric potential. It quantifies the total angular momentum of the particle and its projection along a specific axis. The eigenvalues of the (l2) operator correspond to the possible values of the total angular momentum quantum number (l), which in turn affects the quantum state of the particle in the potential.

How do you increase the angular velocity of a rotating object?
Angular velocity just means how fast it's rotating. If youaa want more angular velocity, just rotate it faster or decrease the radius (move it closer to the center of rotation). Just like force = rate of change of momentum, you have torque= rate of change of angular moment Or We can increase the angular velocity of a rotating particle by applying a tangential force(i.e. accelaration) on the particle. Since the velocity of the particle is tangential with the circle along which it is moving, the tangential accelaration will not change the diriction of the velocity(as angle is 0),but will cause a change in magnitude. Thus angular velocity will increase.
If a particle moves in a straight line is its angular momentum zero with respect to any arbitary acis?
Yes, for a particle moving in a straight line, its angular momentum is zero with respect to any arbitrary axis.

What is a radian?
In the better-known degrees, a full circle is divided into 360 degrees. Radian is another angular measurement, where a full circle is dividied into (2 x pi) units called radians. In other words, the arc along a circle of radius 1. The radian is the "natural" unit of angular measurements; several calculations are simpler when angles are in radians, especially in advanced math topics.
What is the difference betweentangential velocity or angular velocity?
angular velocity s the rotational analague of linear velocity...direction of linear velocity s along tangent to the circle while that of angulr velocity s along the axis of rotation.the direction of angular v can be find by right hand rule which state that if the axis of rotation s held n right hand with fingers curled round the direction of rotation then the thumb will mark the direction of angular velocity.... the magnitude of angular velocity that s the angular speed is represented by the length of the line along the axis of rotation...its units are rad/sec,degrees/sec or revolution/sec while that of linear velocity s m/sec...
What is spin up and spin down in quantum physics?
In quantum physics, "spin up" and "spin down" refer to the two possible orientations of an elementary particle's intrinsic angular momentum, or spin. These terms are used to describe the projection of the particle's spin along a specified axis. The spin can be thought of as the particle's intrinsic magnetic moment.
What does right ascension measure?
Angular distance eastward along the equator.
Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
Yes, suppose a body is rotating anti-clockwise, then its angular velocity and angular momentum, at any moment are along axis of rotation in upward direction. And when body is rotating clockwise, its angular velocity and angular momentum are along axis of rotation in downward direction. This is regardless of the fact whether angular velocity of the body is increasing or decreasing.
What is the difference between radial and angular nodes in the context of atomic orbitals?
Radial nodes are regions in an atomic orbital where the probability of finding an electron is zero along the radius from the nucleus, while angular nodes are regions where the probability of finding an electron is zero along specific angular directions. Radial nodes are spherical in shape, while angular nodes are planar or conical.
