Adoption process of the SI system by all the worlds nations is called Metrication or metrification.
Metrication or metrification is defined as conversion to the metric system of units of measurement. Earlier, many traditional and local systems were used for conversion but since last 2 centuries, most of the countries have adopted the SI system that is widely used as system of measurement.
This would be a geocentric model.
It was proposed due to religion before the Renaissance in Italy, and was later replaced with the current heliocentric model.
Work,
in thermodynamics, is the amount of energy that is transferred from one system
to another system without transfer of entropy. It is equal to the external
pressure multiplied by the change in volume of the system. It is expressed as
follows:<span>
W = PdV
Integrating and assuming that P is not affected
by changes in V or it is constant, then we will have:
W = P (V2 - V1)
Substituting the given values:
P = 1.0 atm = 101325 Pa
(V2 - V1) = 0.50 L =
W = 101325 N/m^3 ( 0.50) (1/1000) m^3
W = 50.66 N-m or 50.66 J

So, in the expansion process about 50.66 J of work is being done.

The correct answer is B. The safety only prevents you from pulling the trigger, but does not stop the pin from striking the primer. For example, if you drop the firearm, the pin may hit the primer and fire the firearm. It is always responsible to keep the firearm pointed in a safe direction so that if this happens, no consequences come out of it.
Answer:
If the object is placed between Focus and centre of Curvature, the image forms beyond centre of curvature. If the object is placed at principal focus the image forms at infinity . If the object is placed between the pole and the principal focus, the image forms behind the mirror.
