The strength of the electromagnet will be increased with increase in the voltage of the battery and increase in the number of turns of the coil.
Answer: Option C
<u>Explanation:
</u>
An electromagnet is generated by passing current through a magnetic material. As per Faraday’s law, magnetic field will be maintained till there is presence of electric flux in the circuit. Thus, like a solenoid, the number of turns of the copper wire on the iron nail will be directly proportional to the strength of the electromagnet.
This is because each turn of the copper wire will act a small region of electromagnet which when added up will lead to increase in the strength of the electromagnet. Similarly, the electromagnet's strength will also increase when the current flowing in the solenoid is increased.
As the current flow in a circuit is proportional to the battery's voltage used, the increase in the voltage will lead to increase in the flow of current in the solenoid structure. Thus, the increase in voltage as well as the coil's turn number leads to increase in the electromagnet's strength.
Ptotal=Ptotal —> m1v1+m2v2=m1v1’+m2v2’ —> (1kg)(2m/s)+(1kg)(0m/s)=(1kg)(-1m/s)+(1kg)(v2’) —> v2’=3m/s
answer: v=3m/s
Answer:
A. The upward pressure gradient force is balanced by gravity.
Explanation:
A. is correct because the pressure difference is actually generated by gravity. As in the following formula for the pressure at different points:
where 
are the pressure at 2 points, ρ is the density of the fluid, g is the gravitational constant, and h is the height difference.
B is incorrect because friction in air is too small to make an effect.
C is incorrect because the Coriolis force is horizontal, not vertical.
D is incorrect because a difference of 500 hPa = 50000 Pa, this is half of the atmospheric pressure.
E is incorrect because temperature cannot generate force.
Answer:
minimizes
Explanation:
The center of gravity method consists of an algorithm for the location of an installation considering existing ones. This is a very simple technique and is usually used to determine the location of intermediate warehouses and distribution points taking into account the distances that separate them and the contribution (in terms of utility, production or capacity) of each installation.
This location method takes into account three transport factors:
Ci: Transportation cost per unit
Vi: Volume transported from unit i
di: Distance traveled in the transport of the unit i
The primary objective of this method is to find the best location of a given installation of a company with respect to the other elements that make it up, to guarantee the minimum possible time and the minimum Total Transportation Cost.
