Answer:
The energy of photon, ![E=8\times 10^{-15}\ J](https://tex.z-dn.net/?f=E%3D8%5Ctimes%2010%5E%7B-15%7D%5C%20J)
Explanation:
It is given that,
Voltage of anode, ![V=50\ kV=50\times 10^3\ V=5\times 10^4\ V](https://tex.z-dn.net/?f=V%3D50%5C%20kV%3D50%5Ctimes%2010%5E3%5C%20V%3D5%5Ctimes%2010%5E4%5C%20V)
We need to find the maximum energy of the photon of the x- ray radiation. The energy required to raise an electron through one volt is called electron volt.
![E=eV](https://tex.z-dn.net/?f=E%3DeV)
e is charge of electron
![E=1.6\times 10^{-19}\times 5\times 10^4](https://tex.z-dn.net/?f=E%3D1.6%5Ctimes%2010%5E%7B-19%7D%5Ctimes%205%5Ctimes%2010%5E4)
![E=8\times 10^{-15}\ J](https://tex.z-dn.net/?f=E%3D8%5Ctimes%2010%5E%7B-15%7D%5C%20J)
So, the maximum energy of the x- ray radiation is
. Hence, this is the required solution.
Answer:
714.285s
Explanation:
use relative velocity
8-4.5 = 3.5m/s
x = 2500m
2500/3.5 = 714.285s = 700s (with sig figs)
Speed is scalar, meaning it's only going to be like 74 mph, doesn't matter which direction. Velocity is a vector, meaning it has direction. You can go -74mph when talking about velocity, not speed.
According to the Law of Conservation of Energy, energy is neither created nor destroyed. It is only transferred through different forms of energy. For the following situations, the conversion of energy is as follows:
*Turning on a space heater = electrical energy⇒heat energy
*Dropping an apple core into the garbage = potential energy⇒kinetic energy
*Climbing up a rope ladder = kinetic energy⇒potential energy
*Starting a car = chemical energy⇒mechanical energy
<span>*Turning on a flashlight = chemical energy</span>⇒electrical energy
