Answer:
Please see below as the answer is self- explanatory.
Explanation:
- Any time that an object changes direction (from leftward to rightwward, or from upward to downward) the velocity must be zero just for one instant, when is on the verge of changing the direction.
- This is needed because velocity changes as a continuous function of time, so it needs to cross the t-axis when passing from positive to negative or vice versa.
- However, the claim that in the moment that velocity is zero, the acceleration is also zero, is false.
- Due to acceleration is the rate of change of velocity, and velocity is a vector, this means at any time there is a change of direction, there is an acceleration that is non-zero.
- For example, when an object that has been thrown upward, reaches to its maximum height, just one instant before starting to fall, the velocity becomes zero, but the acceleration (which causes the object to fall) is non-zero, due to it's the acceleration due to gravity.
Answer:
A yard is shorter than a meter.
Explanation:
>>>1 yard is 0.914 m, so a yard is shorter than a meter.
>>>1 mile is 1.609 km, so a mile is longer than a kilometer
>>>1 foot is 30.48cm, so a foot longer than a centimeter
>>> 1 inch is 2.54cm, so an inch is longer than a centimeter
From the above relationships, only a yard is shorter than a meter is true. Others are wrong.
The tendency of an object to resist change in its motion is known as inertia
I think the answer is reflection but I might be wrong
