A stone is thrown straight up. While the stone is rising: Group of answer choices its acceleration is upward and decreasing its acceleration is upward and constant its acceleration is upward and increasing its acceleration is zero None of the available answers are correct. its <u>acceleration </u><u>is zero</u>
<h3>What is
acceleration ?</h3>
The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force acting on an object determines the direction of its acceleration.
According to Newton's Second Law, the amount of an object's acceleration depends on two factors: the net balance of all external forces acting on the object; the magnitude of the acceleration is directly proportional to the net resulting force. For instance, when a vehicle begins at rest (zero velocity in an inertial frame of reference) and moves straight ahead at increasing speeds, it is accelerating in the direction of travel.

Answer:
Pluto is no longer considered a planet as a result of it's small size on the IAU scale.
Explanation:
Heat transfer is limited to conduction and radiation only in anomalous expansion of water simply because of the temperature at which the expansion occurs and density
<h3>What is anomalous expansion of water?</h3>
Anomalous expansion of water is a property of water in which water expands instead of contracting.
- Anomalous expansion of water makes water less dense.
- The major effect of this anomalous expansion it will still remain less dense and at the surface of water.
- Interestingly, this expansion occurs when it is cooled from 4°C to 0°C.
