heck up only the correct statement in the following.A body has a constant velocity and still it can have a varying speedA body has a constant speed but it can have a varying velocity.A body having constant speed cannot have any acceleration.None of these.

( ii ) A body whose speed is constant(a) Must be accelerated(b) Might be accelerated(c) Has a constant velocity(d) Cannot be accelerated.

When the velocity of a body is variable, then :Its speed may be constantIts acceleration may be constantIts average acceleration may be constantAll of the above

If an object has a constant acceleration, the velocity of the object must:*be zerobe constantcontinually change by the same amount each secondcontinually change by varying amounts each second

It is impossible for an object to have:constant speed and constant velocityconstant speed and changing velocitychanging speed and constant velocitychanging speed and changing velocity

Which of the following situations is true and possible?a. If the velocity of a body is zero, then the acceleration can be non-zerob. A body moving at a constant velocity can have accelerationc. The magnitude of distance and displacement are equal in a circular motiond. All of the above
