Because 'acceleration' does NOT mean 'speeding up'.
It means ANY change in motion ... speeding up, slowing down,
or changing DIRECTION.
When traveling a roundabout, or any curved path, the direction
is constantly changing even if the speed is constant, so there is
constant acceleration going on.
Explanation:
Motion is when an object changes position over time. The object in motion is usually in front of a reference point-an object that appears to stay in one place. The rate at which an object moves is called speed. Speed depends on both time and distance. The velocity of an object is how fast it is going in one direction
How do you know if an object has changed position?
changes position requires a point of reference. An object changes position if it moves relative to a reference point. To visualize this, picture yourself competing in a 100-m dash. You begin just behind the start line
Answer:it gets converted to light energy
Explanation:hope this helps
To solve this problem it is necessary to apply the continuity equations for which it is defined that the proportion of Area in the initial section is equal to the final section. In other words,
Where,
Cross sectional area at each section
Velocities of fluid at each section
The total area of the branch is eighteen times of area of smaller artery. The average cross-sectional area of each artery is 
Therefore the Cross-sectional area at the end is
Applying the previous equation we have then
The ratio of the velocities then is
Therefore the factor by which the velocity of blood will reduce when it enters the smaller arteries is 0.1349
Within a single medium, the product of (wavelength) x (frequency)
is always the same number, for all waves. (It's the wave-speed.)
This means that longer wavelengths must have lower frequencies,
and shorter wavelengths must have higher frequencies, in order for
the product to always come out to be the same.
