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>
Answer: It takes the stone 7seconds in air and 5seconds in water
Explanation: complete question: How long did the stone fall in air and how long did it fall in the water?
total distance = sum of velocity * time for both legs of the journey;
let the time taken in air be t
hence time taken in water is 12-t
127 = 16*t + 3(12-t)
127 = 16t + 36 - 3t
127 - 36 = 16t - 3t
91 = 13t
t = 91/13 = 7 seconds
Hence time taken in air = 7 seconds
time taken in water is 12 - 7 = 5 seconds
Answer:
35.55 ohm
Explanation:
C = 80 micro farad
F = 56 hertz
Reactance
Xc = 1 / (2 × pi × F × C)
Xc = 1 / ( 2 × 3.14 × 56 × 80 × 10^-6)
Xc = 35.55 ohm
Explanation:
The following measures can be taken to prevent or control high temperature caused by thermal pollution:
1. Heated water from the industries can treated before discharging directly to the water bodies.
2. Heated water from the industries can be treated by the installation of cooling ponds and cooling towers.
3. Industrial treated water can be recycled for domestic use or industrial heating.
4. Through artificial lakes: In this lake Industries can discharge their used or heated water at one end and water for cooling purposes may be withdrawn from the other end. The heat is eventually dissipated through evaporation.
True
Explanation:
In order to apply and experience the beauty of mathematics, a good comprehension of the discipline is required.
In fact, this is general to anything in life. To fully maximize any potential, one must be well groomed about what exactly that thing is.
Mathematics is a science that deals with the logic of shapes and numbers. There are different branches of this discipline with real world adoption.
The tenets of mathematics cuts across business, science, arts, e.t.c.
