S.I. System is same for all countries, so if any Scientist uses it, then another Scientist from any place around the world can figure it out, that what is he saying, how exactly is the magnitude of the object. That's why it is a Consistent system

Hope this helps!

The SI system or System Internationale is measuring system used around the world with the exception of some previous dominions of the United Kingdoms.

The units used to meaure fields, like distance is measured in meters (m), translate to all languages with shortcase symbols and the actual unit word having no variency.

For example :
The unit for luminous intensity in English is candela (cd)
In French the words for luminous intensity is "Intensité lumineuse," however the unit is still candela (cd)

SI units are also used as the main components of derived units such as Newtons (N), Omhs (Ω)

if i roll pieces of allium foil in a ball what property of aluminium foil changes as a result of my action

MArishka [77]

Answer:

Malleability

Explanation:

The ability to roll aluminum foil in a ball is the property of metal called malleability.

Metallic bonds in metals makes it possible for them to take different shape without losing internal cohesion.
Metals are malleable and they posses a wide range of physical properties.
A malleable metal can be beaten into sheets and molded into many shapes.

Niobium metal becomes a superconductor when cooled below 9 K. Its superconductivity is destroyed when the surface magnetic field

morpeh [17]

To develop the problem it is necessary to apply the concepts related to Magnetic Field.

The magnetic field is defined as

$B = \frac{\mu_0 I}{2\pi r}$

Where,

$\mu_0 =$ Permeability constant in free space

r = Radius

I = Current

Our values are given as,

B = 0.1T

d = 4.5mm

r = 2.25mm

If the maximum current that the wire can carry is I, then

$B = \frac{\mu_0 2I}{4\pi r}$

$I = \frac{Br}{2\frac{\mu_0}{4\pi}}$

$I = \frac{(0.1T)(2.25*10^{-3}m)}{2(1*10^{-7}N/A^2)}}$

$I = 1125A$

Therefore the maximum current is 1125A

If a car is traveling 100 km/h west and comes to a stop in 3 min, what is the car's acceleration? Need procedure.

zmey [24]

Answer:

a = 0.154 [m/s^2]

Explanation:

To solve this problem we must use the following formula of kinematics.

$v_{f}= v_{i}-(a*t)\\$

where:

Vf = final velocity = 0

Vi = initial velocity = 100 [km/h]

t = time = 3 [min] = 180 [s]

Now we need to convert the velocity from [km/h] to [m/s]

$100[\frac{km}{h} ]*1000[\frac{m}{1km} ]*1[\frac{h}{3600s} ]=27.77[\frac{m}{s} ]$

0 = 27.77 - (a*180)

a = 0.154 [m/s^2]

Note: the negative sign of the equation shows, that the car slows down until it stops

Which three characteristics of an object are represented by a motion map?

Reptile [31]

Answer:

Last option: position, acceleration, velocity

Explanation:

Motion maps are generally used in Kinematics to visualize the object's position (normally with pictures of the object) at different times, and its state of motion with vectors indicating its velocity and its acceleration at those times.
