Because "velocity" means the speed and direction of the motion.
In circular motion, or motion on any curved path, the direction is constantly changing. So even if the speed isn't changing, the <em>velocity</em> is.
The correct answer is: <span>The water and ions lost through perspiration must be replaced during recovery so the body can replenish fluid and stored energy
This is the relation of perspiration to recovery after exercise. That is why it is important to replenish the body with water to avoid dehydration. </span>
Answer: kinetic energy
Explanation: Kinetic energy has motion which is a moving object
Answer:
e=0.374V
Explanation:
the induced voltage is the work done per unit of charge. Hence we have
![\epsilon=\frac{W}{q}=\frac{FL}{q}=\frac{qvBLsin\theta}{q}](https://tex.z-dn.net/?f=%5Cepsilon%3D%5Cfrac%7BW%7D%7Bq%7D%3D%5Cfrac%7BFL%7D%7Bq%7D%3D%5Cfrac%7BqvBLsin%5Ctheta%7D%7Bq%7D)
however, the angle between the piece of conductor and the field is 0°. Hence
![\epsilon=vBL=(4.0\frac{m}{s})(1.7T)(0.055m)=0.374V](https://tex.z-dn.net/?f=%5Cepsilon%3DvBL%3D%284.0%5Cfrac%7Bm%7D%7Bs%7D%29%281.7T%29%280.055m%29%3D0.374V)
THE INDUCED VOLTAGE IS 0.374V

Answer:
an example of when friction is a hindrance, is if someone with shorts is sliding down a slide. their skin rubbing on the slide will cause friction and will slow them down. another example is if you're dragging a large wooden box across the floor. the wood and the floor interacting cause friction and will make it more difficult to push the box.
