Explanation:
The area of the circular loop is given by:
The magnetic flux is given by:
is parallel to and is constant in magnitude and direction therefore:
Part A)
initially the flux is
after the interval
the flux is
now, the EMF is defined as:
,
if we consider very small then we can re-write it as:
then:
Part B)
When looked down from above, the current flows counter clockwise, according to the right hand rule, if you place your thumb upwards (the direction of the magnetic field) and close your fingers, then the current will flow in the direction of your fingers.
The correct answer for this question is this one: "b. increased prices." <span>The small increase in global oil production coupled with an increased demand for those resources leads to increase in prices.
</span>
Here are the following choices.
<span>a.
lack of modern energy sources
b.
increased prices
c.
decreased competition
d.
decreased prices</span>
Taking the vertical component of the displacement
1.1 - 0.2 = 0.9 mile
The horizontal component of the displacement
-0.3 mile
The magnitude of the displacement is
√[ (0.9)² + (-0.3) ] = 0.95 mile
The direction is
θ = tan-1 (-0.3/0.9)
θ = 161.57 degrees.
Answer:
Explanation:
First last of thermodynamics, just discusses the changes that a system is undergoing and the processes involved in it. It explains conservation of energy for a system undergoing changes or processes.
Second law of thermodynamics helps in defining the process and also the direction of the processes. It tells about the possibility of a process or the restriction of a process. It states that the entropy of a system always increases.
For this to occur the energy contained by a body has to diminish without converting to work or internal energy. So imagine a machine which works with less than efficiency, this means there are losses but they don’t show up anywhere. But the energy is obtained from a higher energy source to lower.
The easy way to do this is with an imaginary device that extracts zero-point energy to heat a quantity of gas. Energy is being created, so the first law is violated, and the entropy of the system is increasing as the gas heats up.
First law is violated since the energy conversion don't apply but the direction of work is applied so second law is satisfied.
Answer:
Charge enter a 0.100 mm length of the axon is
Explanation:
Electric field E at a point due to a point charge is given by
where is the constant =
is the magnitude of point charge and is the distance from the point charge
Charges entering one meter of axon is
Charges entering 0.100 mm of axon is
substituting the value of in above equation, we get charge enter a 0.100 mm length of the axon is
