Answer:
0.333 i1
Explanation:
from figure
iB = i2
i1 = iA
i1 = iA = iB+iC = i2+iC
all resistances are equal o R
i1 = E/[R + 2R||R + R] = E/[8R/3] = 3E/8R
since if v is constant then i is inversely proportional to R
iB/iC = R/2R = 1/2
iC = 2iB = 2i2
and i1 = iB+iC = iB+2iB => i1 = 3iB = 3i2
thus i2 = i1/3
or
the equivalent resistance is
Req = [R || (R+R) ] + ( R + R)
Req = 2R/3 + 2R = 8R/3 ohm
current i1 = E / Req = E / ( 8R/3) = 3E/8R
i1 is divided in two parts as i2 = ib and ic
i1 is divided in i2 and ic in ratio 1 :2
Twice the current will flow through RC as will flow through RB and R2. So the current flowing in R1 and RA is divided by 3,
so i2 is 0.33*i1
i2 = [ 1 / (1+2) ] * i1 = 1/3 * i1
i2 = i1 / 3 = 0.333 i1
Answer:
Because a person may be pulled in the direction of the moving train. Thereby causing accident
Explanation:
According to Daniel Bernoulli's theorem, he was widely known as a Mathematician. He stated that due to the higher velocity of a moving train, there is higher kinetic energy in terms of volume around it, while the air pressure between the person and the train becomes lower.
As a result, a person near a moving train may be pulled in the direction of the moving train. Thereby causing accidents that may lead to death.
Answer:
A closed system.
Explanation:
The three major types of system are: open, closed and isolated. Open system interacts with its surroundings with respect to its particles and energy. A closed system interacts with its surroundings with respect to energy but not its particles. While an isolated system does not interact with its surroundings in any way.
Therefore, after the jar is sealed, it is an example of a closed system. This is because the emitted gas could not escape into the surroundings, but thermal energy was emitted into its surroundings after the chemical reaction has taken place.
