A. True
B. False

1. B 2. A. 3. A. 4. B 5.B

Explanation:

1) The statement is false, because the  acceleration (by definition) is the  rate  of change of velocity, which is a vector.

As a vector, it can change the magnitude, the direction, or both. As the speed is only the magnitudde, there can be an acceleration at constant speed, as in an uniform circular movement, where the acceleration produces a change in direction, not in the speed.

2) If the body is in motion (assuming that it is only translational motion) the position (displacement from the origin) must be change with time, so the statement is true.

3) This is true, as the acceleration, as we said above, is the rate of change of  the velocity vector.

4) The statement is false, as an object moving at constant speed along a straight line is in movement, and is not accelerated at all.

5) The statement is false, as a body can momentarily come to an stop (before changing direction, for instance), and be accelerated at the same time.

The best example is an object thrown up in the air: once released, the only force acting  on it is gravity, which  produces an acceleration in opposite direction to the initial speed, until it causes the object to stop, change direction, and finally fall freely.

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
