If a body is rotating is it necessarily bejng acted upon by an external torque?
No. Just as no force is required to keep a moving body moving in a straight lineat constant speed, no torque is required to keep a rotating body rotating at aconstant speed. External torque is present only if the body's rate of rotation ischanging.
If a body is rotating is it necessarily being acted upon by an external torque?
No, a rotating body can maintain its rotation without an external torque if it has an initial angular momentum or is in space with no external forces. However, if the body experiences a change in its rotation speed or direction, then an external torque is likely acting upon it.
When there is no torque acting on a rotating body which quantities will change?
When there is no torque acting on a rotating body, the angular velocity will remain constant according to the principle of angular momentum conservation. However, if there are any external forces or friction present, they may cause the linear velocity of the body to change.
What is the condition for a body to be in equilibrium?
For a body to be in equilibrium, the net force acting on it must be zero, meaning that the forces in all directions are balanced. Additionally, the net torque (or rotational force) acting on the body must also be zero, ensuring that it is not rotating.
In what direction should a force be applied to produce maximum torque?
In a perpendicular direction to the rotating body.

In orbital motion the Angular Momentum of the system is?
In orbital motion, the angular momentum of the system is constant if there is no external torque acting on the system. This is a result of the conservation of angular momentum, where the product of the rotating body's moment of inertia and angular velocity remains constant unless acted upon by an external torque.

Carbonhydrates are acted on by?
Carbohydrates are acted on by enzymes in the body to convert them to sugar so the body can use them as fuel.
In what direction should a force be applied to produce maximum torque?
In a perpendicular direction to the rotating body.
What is torque and state the conditions of rotational equilibrium?
Torque is analogous to force. As Force produces a change in the state of linear motion of a body, Torque produces a change in the state of rotational motion of a body. The unit is newton meter (Nm) and the symbol is tau (τ) For rotational equilibrium, the algebraic sum of the torques acting on a body must be zero. ie. Στ=0
What is the fastest rotating body in the solar system?
The fastest rotating body in the solar system is the star, Regulus. It has an equatorial rotational velocity of about 288 km/s.
How was Eleonora Duse different from Sarah Bernhardt?
SB acted with her body.. ED acted with her soul !
If a body is acted by a constant force the body will have uniform?
"acceleration"
What is necessary for an object to be in complete rotational and translational equilibrium?
When the vector sum of all the forces acting on a body of mass is zero, the body has zero acceleration (that is, the body's centre of mass moves with constant velocity).In a similar fashion, if the net torque on a body is zero, the body has zero angular acceleration (that is, the body's angular velocity remains constant). This is the condition for rotational equilibrium.
