The first P1 power connector to the motherboard have that
was used with the original ATX contained a 20-pin P1 connector.
The 20-pin ATX style connector or the Molex 39-29-9202 is
the industry standard ATX power-supply–to–motherboard main connector. It is utilized
in the SFX form factor or any other ATX-based variations and was first used in
the ATX form factor power supply.
The ATX standard recommends the colors for the wires that
are listed in Table 3.3, however, they could vary from manufacturer to
manufacturer since they are not required for compliance to the specification. The
pins are arranged looking at the back of the connector (from the wire and not
terminal side) as shown in the table since it shows that its orientation if the
connector plugged in was back-probed.
Answer:
K = 1.29eV
Explanation:
In order to calculate the kinetic energy of the proton you first take into account the uncertainty principle, which is given by:
(1)
Δx : uncertainty of position = 2.0pm = 2.0*10^-12m
Δp: uncertainty of momentum = ?
h: Planck's constant = 6.626*10^-34 J.s
You calculate the minimum possible value of Δp from the equation (1):
The minimum kinetic energy is calculated by using the following formula:
(2)
m: mass of the proton = 1.67*10^{-27}kg
in eV you have:
The kinetic energy of the proton is 1.29eV
These substances are called insulators. We also have a class of substance called a semi-conductor. They share many properties with insulators. You can sometimes see them on telephone poles.
Answer:
2.778m/s
Explanation:
25meters/9seconds=2.778m/s
Answer: You could tell if you made an error in your calculations by repeating the steps.
Speed of light is the fastest/maximum in vacuum which is equal to 3 × 10^8 m/s, therefore speed of light through any material equal to 4 × 10^8 m/s is physically and theoretically impossible and therefore incorrect.
