C) During the radioactive decay, alpha particles are released. These positive particles are attracted to the negative plate in the electric field
Explanation:
In nuclear reactions, it should be known that the mass and atomic numbers are usually conserved.
²³⁸₉₂U → ²³⁴₉₀Th + ⁿₐX
This implies that:
238 = 234 + n
92 = 90 + a
When this is true, then the nuclear reaction is balanced. Both atomic and mass numbers can be said to be conserved.
Solving for n and a
n = 4
a = 2
Therefore
²³⁸₉₂U → ²³⁴₉₀Th + ⁴₂He
The particle resulting from the decay is an alpha particle. Alpha particles resembles a Helium atom.
Alpha particles are positively charged and they are attracted to the negative plate in the electric field.

Answer:
Since the waves must carry a great deal of visual as well as audio information, each channel requires a larger range of frequencies than simple radio transmission. TV channels utilize frequencies in the range of 54 to 88 MHz and 174 to 222 MHz. (The entire FM radio band lies between channels 88 MHz and 174 MHz.)
Answer:
Displacement from the starting position is 103.21m
Explanation:
If you draw these directions, it will create the two legs of a triangle.
Using this method, you can visualize why your displacement is what it is.
Using the pythagorean theorem
Plug in both values
c = 103.2085
c= 103.21
15 = a+(3-1)d
23 = a+(7-1)d
simultaneous eqs. solve for a and d
