lawyer [7]3 years ago
3 0

The ampere (symbol: A) is the SI base unit of electric current equal to one coulomb per second.

The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 times 10–7 newton per meter of length.

Electric current is the time rate of change or displacement of electric charge.

One ampere represents the rate of 1 coulomb of charge per second.

The ampere is defined first (it is a base unit, along with the meter, the second, and the kilogram), without reference to the quantity of charge.

The unit of charge, the coulomb, is defined to be the amount of charge displaced by a one ampere current in the time of one second.

This is your answer friend. Hope it helps you.

1. Compare and contrast the SI and the English systems of measurement.
yulyashka [42]

Answer:The SI system is based on the number 10 as well as multiples and products of 10. This makes it much easier to use, and so it has been the accepted system in scientific and technical applications. The English system is more complicated as relationships between units of the same quantity aren't uniform.

Elenna [48]

Answer:

775 grams of ice

Explanation:

Heat loss by patient = heat gained by ice

Heat loss by patient = mass×specific heat capacity×(initial temperature - final temperature) = 62×4200×(40-39) = 260,400J

Heat gained by ice = mass × specific latent heat of fusion of ice = m×336000 = 336000m J

336000m = 260,400

m = 260400/336000 = 0.775kg = 0.775×1000 grams = 775 grams of ice

A boat traveled at a constant speed for 5 hours, covering a total distance of 132.3 kilometers. how fast was it going?
Llana [10]
Velocity = distance (m) /time (s)

convert kilometers to metres (132300), substitute into formula.

convert hours to seconds (18000), substitute into formula. it becomes,

132300 divided by 18000 = 7.35 M/S 

always answer questions in the units given in the question.

to get m/s into km/h, multiply by 3.6, therefore it equals 24.46 km/h

If a liquid has a refractive index of 1.5323, than the speed of light through that liquid is _______ x 108 m/s. Type your numeri
wariber [46]

Answer:

The speed of the light through that liquid is v=1.95\times 10^8\ m/s.

Explanation:

Given that,

The refractive index of the liquid, \mu=1.5323

We need to find the speed of light through that liquid. Let the speed of light in liquid is v. The relation between the refractive index and the speed of light in the medium. So,

\mu=\dfrac{c}{v}

v=\dfrac{c}{\mu}

v=\dfrac{3\times 10^8\ m/s}{1.5323}

v=1.95\times 10^8\ m/s

So, the speed of the light through that liquid is v=1.95\times 10^8\ m/s. Hence, this is the required solution.
