if your wireless network or network speed through router can not reach broadband speed, then it is likely that it is the problem of router
it is recommended to replace a better router or use al band router to get better service, WiFi language

6.

First of all, your cost includes the transaction fees and taxes. At present, the network transaction fees of general securities companies will be lower. Telephone entrustment and counter entrustment are basically the same. At present, 0.2% is calculated according to the transaction amount

1. The transaction price of a stock is 10 yuan / share, and if you buy 1000 shares, the handling fee you need to pay is 1000 * 10 * 0.2% = 20 yuan; The next day, when the stock price rises and you sell it for 10.5 yuan, the handling charge you have to pay is 1000 * 10.5 * 0.2% = 21 yuan (also excluding stamp ty)

2. Stamp ty should be paid at the time of transaction, which is 0.1% at present, and the calculation method is the same as the handling charge. That is to say, the total amount you actually pay when you buy is 10030 yuan, while the total amount you actually get when you sell is 10500-31.5 = 10468.5 yuan, so your net income is 438.5 yuan. In addition, there are also some small costs, such as the transfer fee of 1 yuan per thousand shares in Shanghai

3. After all transaction costs are defined, the income of the transaction is calculated as follows: income = (income from selling - transaction costs and taxes paid by selling, etc.) - (principal purchased + transaction fees and taxes, etc.)

The so-called income and principal of buying and selling means the unit price of buying and selling multiplied by the number of shares bought and sold. Of course, when the company pays dividends, you have to add the actual income you get

extended information:

ordinary shareholders enjoy the following basic rights according to the proportion of shares they hold:

(1) the right to participate in company decision-making. Shareholders of common stock have the right to participate in the general meeting of shareholders, and have the right to propose, vote and vote. They can also entrust others to exercise their shareholders' rights on their behalf

(2) the right of profit distribution. Common shareholders have the right to receive dividends from the company's profit distribution. The dividend of common stock is not fixed, which is decided by the company's profit situation and its distribution policy. Only after the preferred shareholders get the fixed dividend can the common shareholders enjoy the right of dividend distribution

(3) stock option. If the company needs to expand and issue additional common shares, the existing common shareholders have the right to purchase a certain number of new issued shares at a specific price lower than the market price according to their shareholding proportion, so as to maintain their original proportion of ownership of the enterprise

(4) distribution right of surplus assets. When the company goes bankrupt or goes into liquidation, if the assets of the company remain after paying off debts, the remaining part will be distributed in the order of preferred shareholders first and common shareholders later

7. In what way?

8. Lorentz force
Lorentzforce

the force of magnetic field on moving point charge. When Dutch physicist H.A. Lorentz established the classical electron theory in 1895, it was put forward as a basic hypothesis, which has been confirmed by a large number of experiments. The formula of Lorentz force is f = q · v × B Where Q and V are the electric quantity and velocity of point charge respectively; B is the magnetic inction of the point charge. The Lorentz force is f = q vbsin θ， among θ It's the angle between V and B. The direction of Lorentz force is perpendicular to the plane formed by V and B according to the right-handed screw rule, and is the forward direction of the right-handed screw from V to B (if q is a negative charge, it is reversed). Since Lorentz force is always perpendicular to the direction of charge motion, it does not work on the charge, does not change the rate and kinetic energy of the moving charge, but only changes the direction of charge motion to deflect it
Lorentz force can be applied to both macroscopic and microscopic charged particles. The ampere force on the current element in the magnetic field is the macroscopic expression of Lorentz force on the moving charge. It is also the result of Lorentz force that the conctor loop moves in a constant magnetic field and changes its magnetic flux. Lorentz force is the non electrostatic force that generates the motional electromotive force
if the electric field E and the magnetic field B coexist, the force on the moving point charge is the sum of the electric field force and the magnetic field force, which is f = q (E + V) × B) The left formula is also called Lorentz force formula
Lorentz force formula, Maxwell equations and dielectric equations together form the basis of classical electrodynamics. In many scientific instruments and instrial equipment, such as β Lorentz force is widely used in spectrometer, mass spectrometer, particle accelerator, electron microscope, magnetic mirror device and Hall device< It is worth noting that since ampere force is the macroscopic expression of Lorentz force and Lorentz force does not work on moving charges, why can ampere force work on current carrying wires? In fact, Lorentz force plays the role of transferring energy. One part of Lorentz force hinders the movement of electric charge to do negative work, and the other part constitutes ampere force to do positive work on the current carrying wire. As a result, the energy is still provided by the power supply that maintains the current

9. Hello

Lorentz force refers to the magnetic force that charged particles are subjected to when they move in a magnetic field. There is only one formula to calculate the Lorentz force: F = q v b sin θ，θ Is the angle between the particle velocity V and the magnetic field B. If the velocity is perpendicular to the magnetic field, then f = QV B
to judge the direction of Lorentz force is to use the left hand rule, with the magnetic field passing through the palm, four fingers pointing in the direction of positive charge moving, negative charge moving in the opposite direction, and the thumb pointing in the direction of Lorentz force

I hope I can help you If my answer can help you, please give me praise, thank you!

10. The direction of the force is determined by the left-handed rule
F = bvq
b is the intensity of the magnetic field
V is the velocity of the particle
q is the charge of the particle
where one of B and V must take the effective value
