Answer:D
Explanation:
Because u have to make observation then ask a question
Explanation:
Substances become neutral at the number 7 because at this point, the acid and Base are equal and becomes neutralized
Answer:
The required force is 55.38 N.
Explanation:
First we have to find the spring constant K;
k =
=
= 553.846 N/m
As,
F= -K
or, F= - 553.846 × 0.10
or, F= -55.3846 N
Hence,
= - 
∴
= 55.38 N
The required force to stretch it by this amount is 55.38 N.

Explanation:
Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.
<u>The conditions required for total internal reflection (TIR) to occur are:</u>
1)the light must be travelling from a more dense medium into a less dense medium (ie glass to air)
2)the angle of incidence must be greater than the critical angle.

Answer:
The current in the second loop will stay constant
Explanation:
Since the induced emf in the second coil, ε due to the changing current i₁ in the first wire loop ε = -Mdi₁/dt where M = mutual inductance of the coils and di₁/dt = rate of change of current in the first coil = + 1 A/s (positive since it is clockwise)
Now ε = i₂R where i₂ = current in second wire loop and R = resistance of second wire loop.
So, i₂R = -Mdi₁/dt
i₂ = -Mdi₁/dt/R
Since di₁/dt = + 1 A/s,
i₂ = -Mdi₁/dt/R
i₂ = -M × + 1 A/s/R
i₂ = -M/R
Since M and R are constant, this implies that i₂ = constant
<u>So, the current in the second wire loop will stay constant.</u>
