In magnets the molecules are uniquely arranged so that their electrons spin in the same direction. This arrangement of atoms creates two poles in a magnet, a North-seeking pole and a South-seeking pole. The magnetic force in a magnet flows from the North pole to the South pole.so if there both south or both north the atoms can’t flow through causing them to stop flowing
Good luck
Let F be the force acting on the bowling ball.
Work done by force= change in KE
Let F be the force acting on the bowling ball
Work done by force = change in KE
F .d = 0.5 m V^2 + 0.5 x I x w^2
F d = 0.5 m ( 1+l) V^2
Solve accordingly to get the answer.
The problem ask to calculate the bullet's flight time and the bullet's speed as it left the barrel. So base on the problem, the answer would be that the flight time is 0.076 seconds and the speed of the bullet is 657.9 m/s. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications.
Explanation:
Precision represents that how close the different measurements of the sample one take are to one another.
- One can increase the precision in lab by paying attention to each and every detail.
- Usage of the equipment properly and also increasing the sample size.
-
Ensuring that the equipment is calibrated properly. They should be clean and functioning. Using equipment which is not functioning correctly can cause results to swing wildly and also bits of the debris stuck to the equipment can influence the measurements of the mass and the volume.
- Each measurement must be taken multiple times, especially if experiments in which combining of the substances in specific amounts is involved.
Time = distance / speed
T = 125/ 5
T = 25 meters per second
