Step-by-step explanation:
A) as you can see there is no current flowing in a bar magnet so (incorrect)
B) Lines of magnetic field is going in A-->B direction so it have starting and ending points.(incorrect)
C) Yes whenever a magnetic object is placed near the another magnetic object they either attract or repell so they have a force in a form of push and pull [correct]
D)No because magnetic field lines goes from North--> South so A is the South pole [ incorrect]
E) Yes it will point always towards North pole of the magnet [correct]
F) yes it depends upon the density of field lines[correct]
G)No the near the magnet is it becomes more stronger as compared to magnet kept far.(incorrect)
So option C E F are correct
Hope this helps
Have a great day
Answer:
5/8
Step-by-step explanation:
28x + 4 can be factorised because 28 is a multiple of 4
so it can become
4(7x+1)
35x + 5 can be also factorised because 35 is a multiple of 5
5(7x+1)
we can now rewrite the expression as
6/4(7x+1) * 5(7x+1)/12
we can “eliminate” the two 7x+1 and simplify 6 with 12
so it remains
1/4 * 5/2 = 5/8
<span>lim (x → π/2) (sinx)^(tanx)
= lim (x → π/2) e^[(tanx) ln (sinx)]
= e^ [lim (x → π/2) (tanx) ln (sinx)] ... (1)
lim (x → π/2) (tanx) ln (sinx)
= lim (x → π/2) [ln(sinx) / cotx]
Using L'Hospital'stheorem,
= lim (x → π/2) [- cotx / cosec^2 x]
= 0
Plugging in ( 1 ),
required limit = e^0 = 1
=>Answer is 1.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.

The answer is C. The rest of the answers make no sense and do not work.
Answer:
Option D is correct.
Step-by-step explanation:
Given that
A ray is a defined term we have to give the reason of the above statement.
A ray is a line or a part of a line that has one endpoint which we defined and other goes on infinitely in only one direction.
One of the example is a sun's ray of light in space. Light from the sun originates and travels from the sun, and its path extends infinitely.\
Hence, we say that "A ray is a defined term because it travels forever in one direction"
Option D is correct.
