Answer:
Explanation:A driver slowing down to stop at a light is accelerating. ... acceleration is opposite to the motion, the speed of the object decreases. The car slows down. Slowing down is also called negative acceleration.
I think it is A <span>High levels of muscular fitness can improve your self-image and improve or prevent chronic diseases such as diabetes, osteoporosis, and cardiovascular disease.</span>
Power is calculated by dividing the work done with the time interval of the motion. Work, on the other hand, is force times the distance traveled. Therefore, we can calculate as follows:
60.0 mi/h = 26.82 m/s
The car accelerates at:
<span>v2 = v1 + at </span>
<span>a = [v2 - v1] / t </span>
<span>a = 1.49m/s² </span>
<span>The distance it travels at this acceleration in 15.0 s is: </span>
<span>d = [v1 + v2] t / 2 </span>
<span>d = (0 + 22.4m/s)15.0s / 2 </span>
<span>d = 168m </span>
<span>P = m (a)(d) / t </span>
<span>= (1300kg) (1.49m/s²) (168m) / 15.0s </span>
<span>= 22,700 W</span>
Answer:
Electric dipole
Explanation:
the dipole axis makes an angle with the electric field. depending on direction (clockwise/aniclockwise) you get the torque
