Vernier Caliper
It is counted in the list of quality measuring instruments, which are used to measure small parameters with high accuracy. It has got two different jaws to measure outside and inside dimensions of an object. It can be a scale, dial or digital type Vernier calliper
By conducting exhaustive, high-intensity online research for about 15 seconds, I found a source that says the speed of sound in copper is 4600 m/s. (You could easily have completed the same research project in about 1/3 of the time it took you to type and post the question here.)
Time it takes = (distance) / (speed)
Time = (25,000 meters) / (4600 m/s)
Time = (25 / 4.6) km-sec/km
<em>Time = 5.43 seconds </em>
Ice, which is the solid state of water, the liquid
Answer:
Electric field will be
Explanation:
We have given diameter of the copper d = 2.05 mm
So radius
We know that area
Current is given as i = 4.7 A
So current density
Resistivity is given
We know that electric field is given by
