I believe the correct answer is a.) conduction <span />
Neither energy nor matter can enter and exit an isolated system.
Explanation:
There are three types of systems which refers to universe. They are
1. Open System : In an open system, both energy and matter have external interactions. Example:- boiling water in an open pan.
2. Closed system : In a closed system, only energy has interaction with surroundings. Example:- boiling water with a lid on the pan.
3. Isolated system : In an isolated system, neither energy-nor matter has external interactions with surroundings. Example : a thermos flask does not exchange energy and matter.
Hence, the correct option is (a) " neither energy nor matter ".
Answer:
v = λf = (4 m)(3 Hz) = 12 m/s
Explanation:
Answer:
Total magnification is the amount of magnification that can be achieved when all the optics involved in the magnification by the apparatus being used is taken into account.
Explanation:
Total magnification is the amount of magnification that can be achieved when all the optics involved in the magnification by the apparatus being used is taken into account. For example when an object is viewed under a microscope with just ocular and objective lenses, the object is magnified to it maximum magnification using both the ocular lens and objective lens and the total magnification can be calculated by multiplying the power of the objective lens and the power of the eye piece.
Total magnification = power of objective lens x power of eyepiece
Speed =distance/time
3.25=3.00/time
3.25xt=3.00
t=3/3.25
s=0.9s
