Answer:
a) F = 2.7 10⁻¹⁴ N
, b) a = 2.97 10¹⁶ m / s² c) θ = 14º
Explanation:
The magnetic force on the electron is given by the expression
F = q v x B
Which can be written in the form of magnitude and the angle found by the rule of the right hand
F = q v B sin θ
where θ is the angle between the velocity and the magnetic field
a) the maximum magnitude of the force occurs when the velocity and the field are perpendicular, therefore, without 90 = 1
F = e v B
F = 1.6 10⁻¹⁹ 2.40 10⁶ 7.10 10⁻²
F = 2.73 10⁻¹⁴ N
F = 2.7 10⁻¹⁴ N
b) Let's use Newton's second law
F = m a
a = F / m
a = 2.7 10⁻¹⁴ / 9.1 10⁻³¹
a = 2.97 10¹⁶ m / s²
The actual acceleration (a1) is a quarter of this maximum
a1 = ¼ a
a1 = 7.4 10¹⁵ m / s²
With this acceleration I calculate the force that is executed on the electron
F = ma
e v b sin θ= ma
sin θ = ma / (e v B)
sin θ = 9.1 10⁻³¹ 7.4 10¹⁵ / (1.6 10⁻¹⁹ 2.40 10⁶ 7.10 10⁻²)
sin θ = 6.734 10⁻¹⁵ / 27.26 10⁻¹⁵
sin θ = 0.2470
θ = 14.3º
Nuclear energy is energy that is stored in the core of a certain type of atom. Atoms are the smallest units of matter and they make up everything in our universe. Energy is what causes the core of an atom to stay together and inside the core, there is vast amounts of energy.
Answer:
12.5N
Explanation:
Data;
W = 50N
Fh = 15N
μ = 0.4
Fv= ?
The second attachment is showing the resolution of the vectors.
The normal force acting on the box (N) = W - Fv
The frictional force ( ⃗f) = Fh
Frictional force ⃗f = μN = μ(W - Fv)
μW - μFv = Fh
Fv = W - (Fh/μ)
Fv = 50 - (15/0.4) = 50 - 37.5
Fv = 12.5N
The smallest vertical force which moves the box is 12.5N
C. Solvent
A solvent is a substance that can be dissolved. A solute is a substance dissolve in a solvent. Saturated is something where it holds as much of a substance as it can. Precipitate means it's evaporated.
