Answer:
The height is the same
Explanation:
Because they were at the same height but they fell at different velocities
In series circuit, Req = R₁ + R₂ + R₃ + ···
In parallel circuit,
<h3>Q7.</h3>
total resistance in the upper branch = R₂ + R₃ = R₂ + 2
R₂ + 2 = 12
R₂ = 10Ω
<h3>Q8.</h3>
Req = 1.7Ω
Answer:
There are 5847.95 lines per cm for the grating.
Explanation:
Given that,
Wavelength of mercury line,
Angle in the third order spectrum,
Using the grating equation, we get :
Here, m = 3
Let there are N lines for the grating. So,
So, there are 5847.95 lines per cm for the grating.
