Answer:
Explanation:
f = Frequency = 75 Hz
B = Magnetic field =
d = Diameter of cell =
t = Time taken
= Angular frequency
The expression of emf is
Emf is maximum when and N = number of turns = 1
The maximum emf that can be generated around the perimeter of a cell in this field is
Answer:
C
Explanation:
When a ball rolls down a hill, Potential Energy Conversion takes place to Kinetic Energy.
Answer:
17.85°
Explanation:
To find the angle to the normal in which the light travels in the aqueous fluid you use the Snell's law:
n1: index of refraction of Sophia's cornea = 1.387
n2: index of refraction of aqueous fluid = 1.36
θ1: angle to normal in the first medium = 17.5°
θ2: angle to normal in the second medium
You solve the equation (1) for θ2, next, you replace the values of the rest of the variables:
hence, the angle to normal in the aqueous medium is 17.85°
The layer of soil that contains the most organic material is called the a horizon.
Your answer will be A.
