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.

the answer for 0.429m to mm is 429
Answer:
The instrument is thermometer
<h3>a. The impulse</h3>
The impulse is 100.0 Ns
The impulse I = Ft where
- F =average force = 50.0 N and
- t = time = 2.0 s
Substituting these values into the equation, we have
I = Ft
I = 50.0 N × 2.0 s
I = 100.0 Ns
The impulse is 100.0 Ns
<h3>b. Change in momentum</h3>
The change in momentum is 100 kgm/s
Since change in momentum Δp = I where I = impulse.
Since I = 100.0 Ns,
Substituting this into the equation, we have
Δp = I
= 100.0 Ns
= 100 kgm/s
The change in momentum is 100 kgm/s
<h3>c. Mass's change in velocity</h3>
The change in velocity is 25.0 m/s
Since change in momentum Δp = mΔv where
- m = mass = 4.0 kg and
- Δv = change in velocity.
Making Δv subject of the formula, we have
Δv = Δp/m
Substituting the values of the variables into the equation, we have
Δv = Δp/m
Δv = 100.0 kgm/s/4.0 kg
Δv = 25.0 m/s
The change in velocity is 25.0 m/s

Explanation:
Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance. Speed is how fast something is going at a particular moment. Average speed measures the average rate of speed over the extent of a trip.
