No because there must be an even # if their is an even amount one of the forces isn’t being cancelled
Answer:
h = 3.1 cm
Explanation:
Given that,
The volume of a oil drop, V = 10 m
Radius, r = 10 m
We need to find the thickness of the film. The film is in the form of a cylinder whose volume is as follows :

So, the thickness of the film is equal to 3.1 cm.
Answer:
2.9 M
Explanation:
The concentration-time equation for a second order reaction is:
1/[A] = kt + 1/[A°]
Where,
A = concentration remaining at time, t
A° = initial concentration
k = rate constant
1/[A] = (1.80 x 10^-3) * (45.6) + 1/3.81
1/[A] = 0.345
= 1/0.345
= 2.9 M.
<h2>The emf produced is 7.2 V</h2>
Explanation:
When coil is placed in the magnetic field , the flux attached with it can be found by the relation . Flux Ф = the dot product of magnetic field and area of coil .
Thus Ф = B A cosθ
here B is magnetic field strength and A is the area of coil .
The angle θ is the angle between coil and field direction .
When coil rotates , the angle varies . By which the flux varies . The emf is produced in coil due to variation of flux . The relation for this is
The emf produced ξ = -
= B A sinθ 
Now in the given problem
5 = 0.38 x A x
I
Now if the magnetic field is 0.55 T and all the other terms are same , the emf produced
ξ = 0.55 x A x
Ii
dividing II by I , we have
=
= 1.45
or ξ = 7.2 V
a. linear pairs, when added together, the angles will make 180 degrees, or a straight line. In this case No, for when you combine the two angles, it is not a straight line
b. False. Vertical angles make two opposite angles that are congruent
c. True. When added together, angles 1 and 4 make a straight line
d. False. As stated for question b, the two opposite angles must be congruent
hope this helps
