What are the two ways to determine the negative leg of an LED?

Physics

There are three main ways to find which end is positive and negative on LED.  First there is occasionally on the base of the LED<span> a flat part which you would use to identify that as the negative end. Second way is to look at the length of the ends occasionally they will both be the same size, but most of the time the negative end will be shorter. And finally, LED the electrodes of the negative one is the larger of the two. </span>

The net force is 180 and the mass is 1.793 what is the acceleration
nata0808 [166]

Answer:

100.390407

Explanation:

To find acceleration, you would use the formula a=f/m (acceleration equals force divided by mass) and then once you enter those numbers in the formula, a=180/1.793. Then you divide 180 divided by 1.793 which gets you an answer of 100.390407.

You're driving a vehicle of mass 1350 kg and you need to make a turn on a flat road. The radius of curvature of the turn is 71 m
sergey [27]

Answer:

v=12.65\ m.s^{-1}

Explanation:

Given:

  • mass of vehicle, m=1350\ kg
  • radius of curvature, r=71\ m
  • coefficient of friction, \mu=0.23

<u>During the turn to prevent the skidding of the vehicle its centripetal force must be equal to the opposite balancing frictional force:</u>

m.\frac{v^2}{r} =\mu.N

where:

\mu= coefficient of friction

N= normal reaction force due to weight of the car

v= velocity of the car

1350\times \frac{v^2}{71} =0.23\times (1350\times 9.8)

v=12.65\ m.s^{-1} is the maximum velocity at which the vehicle can turn without skidding.
