They are helium nuclei, which consist of two protons and two neutrons. The net spin on an alpha particle is zero. They result from large, perilous atoms via a process called alpha decay.
<h3>What is
helium nuclei?</h3>
- The nucleus of the helium atom also understood as the α-particle, includes two protons and two neutrons, encompassed by two electrons.
- Alpha particles are helium nuclei with two protons and two neutrons attached. The development of their high mass and an electrical charge is their inability to infiltrate as deep as other particles such as protons and electrons.
- Particle beams contain α (alpha)-particles, β (beta)-particles, neutron beams, etc. α-particles are helium middles consisting of two protons and two neutrons that have lived removed at high speed, while β-particles are electrons removed from a nucleus. Particle shafts also include neutron beams and proton beams.

Answer:
1/8 x C
Explanation:
The capacitance of parallel plate capacitor
= ε₀ A /d where A is area of plate and d is distance between plate.
for capacitor 1
C = ε₀ A /d
For capacitor 2
radius = R/2
Area = A / 4
Capacitance
= ε₀ (A/4) x ( 1 / 2d )
= ( 1 / 8) x (ε₀ A /d)
= 1/8 x C
I think the answer would be letter B.
"An object at rest will remain at rest unless acted on by an outside force" is the one statement among the following choices given in the question that provides an example of a scientific theory. The correct option among the two options that are given in the question is the first option or option "a". I hope the answer helped you.
Answer:
The angle of bend = 20°
Explanation:
Since the question describes that the angle marking is similar to the metre stick marking.
The length of the object when it begins at 0 meters on the meter rule
= 1.2 m
The length of the meter stick when it begins at 0.2 m on the meter rule
= 1.0 m
The difference in length of the object based on the markings
= 1.2 - 1.0 = 0.2 m
If the green marking is on 223°, i.e. θ₂ = 223°
and the straight marking is on 253°, i.e. θ₁ = 253°
The angle of bend = θ₁ - θ₂
The angle of bend = 253° - 223°
The angle of bend = 20°
