An electron moving horizontally to the right with speed v enters a region where a uniform magnetic field exists pointing into th
koban [17]

Answer:

W = 0

Explanation:

When an electron moves perpendicular to a uniform B-field. If the field is in a vacuum, the magnetic field B is the dominant factor determining the motion. Since the magnetic force F is perpendicular to the direction of travel, an electron follows a curved path in a magnetic field. The electron continues to follow this curved path until it forms a complete circle. Another way to look at this is that the magnetic force F is always perpendicular to velocity v, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected but not the speed.

W = F*d*Cos ∅ = F*d*Cos 90° = 0  where d is the displacement.

The pic shown can help to understand the explanation.

The capacitance of a capacitor depends on what?​
bonufazy [111]

Answer:

The capacitance of a capacitor depends on the charge and voltage of a system. It is also dependent, if present, on the dielectric as well.

General Formulas and Concepts:
<u>Gauss's Law</u>

Capacitance Formula: \displaystyle C = \frac{Q}{V}

  • <em>Q</em> denotes charge
  • <em>V</em> denotes voltage

Dielectric Capacitance Formula:  \displaystyle C = \kappa C_0

  • <em>C₀</em> denotes original capacitance
  • <em>κ</em> denotes the dialectic constant

Explanation:

A <u>capacitor</u> <em>stores</em> charge when run through an electrical current. The <u>capacitance</u> is <em>how much </em>charge a capacitor can hold.

We can define the relationship of capacitance by using the formula. Capacitance is <em>inversely proportional</em> to the potential energy, or <u>voltage</u>, of the system. Therefore, you will need to know what the <u>charge</u> Q of the system as well has voltage V in order to find the capacitance.

If there is a dielectric involved inside the capacitance, you also must incorporate the value of the <u>dielectric constant </u>into your capacitance. A dielectric is <em>directly proportional </em>to the capacitance; the bigger the dielectric constant, the bigger capacitance, as denoted in our equation.

a particle of mass 1.3kg is sliding down a frictionless slope inclined at 30 to the horizontal. the acceleration of the particle
OverLord2011 [107]

Answer:

4.9\ m/sec^2

Explanation:

The computation of acceleration of the particle down the slope is shown below:-

data provided in the question

Particle of mass = 1.3 kg i,e sliding down

Inclined = 30 to the horizontal

based on the above information

Force is given by

N = mg\ cos \theta ............ 1

and sliding force is given by

F = mg\ sin\alpha

a = g(sin\ 30^{\circ})

= 9.8\times \frac{1}{2} m/sec^2

= = 4.9\ m/sec^2

Hence, the acceleration of the particle down the slope is 4.9 m/sec^2
