Charged particles q1=− 4.80 nC and q2=+ 4.80 nC are separated by distance 3.00 mm , forming an electric dipole. The charges are
Dafna1 [17]

Answer:

Electric field, E = 936.19 N/C

Explanation:

It is given that,

Charge 1, q_1=-4.8\ nC=-4.8\times 10^{-9}\ C

Charge 2, q_2=+4.8\ nC=+4.8\times 10^{-9}\ C

Distance between them, d = 3 mm = 0.003 m

Torque, \tau=8\times 10^{-9}\ N-m

Angle between electric field and line connecting the charge, \theta=36.4^{\circ}

We need to find the torque exerted on the dipole. The torque experienced by the dipole in the electric field is given by :

\tau=pE\ sin\theta

p is the dipole moment, p=qd

\tau=qdE\ sin\theta

E=\dfrac{\tau}{qd\ sin\theta}

E=\dfrac{8\times 10^{-9}}{4.8\times 10^{-9}\times 0.003\ sin(36.4)}

E = 936.19 N/C

So, the magnitude of electric field on the dipole is 936.19 N/C. Hence, this is the required solution.

does the pair of equilibria produced by a saddle-node bifurcation have to consist of one that is stable and one that is unstable
Amiraneli [1.4K]

This bifurcation is called a saddle-node bifurcation. In it, a pair of hyperbolic equilibria, one stable and one unstable, coalesce at the bifurcation point, annihilate each other and disappear.

<h3>What is a bifurcation equilibria?</h3>
  • The mathematical study of changes in a family of curves' qualitative or topological structure, such as the integral curves of a family of vector fields or the solutions to a family of differential equations, is known as bifurcation theory.
  • A bifurcation happens when a tiny, gradual change in a system's parameter values (the bifurcation parameters) results in an abrupt, "qualitative," or topological change in the system's behavior.
  • This term is most frequently used to refer to the mathematical study of dynamical systems.
  • Both continuous systems (represented by ordinary, delay, or partial differential equations) and discrete systems can experience bifurcations (described by maps).

A sail boat moves north for a distance of 10 km when blown by a wind 30° east of south with the force of 5.00×10^4 N. how much w
erma4kov [3.2K]
<h3><u>Answer;</u></h3>

a) 5.00 x 10^8 J

<h3><u>Explanation;</u></h3>

The work done to move the sailboat is calculated through the equation;

W = F x d

where F is force and d is the distance.

Substituting the known values from the given above,

                             W = (5.00 x 10⁴ N)(10 km)(1000 m/ 1km)

                                 = 5.00 x 10⁸ J

Thus, the work done is <u>5.00 x 10⁸Joules</u>
