Answer:
Explanation:
From the given information, the LED is operating with a given wavelength of 850 nm or 0.85 μm.
Hence, the material dispersion is
Now, using the pulse spread formula:
Thus, the pulse spreading as a result of material dispersion is:
Answer:
Velocity will be
Explanation:
We have given mass of alpha particle m = 4 u
Charge on alpha particle
Charge on thorium particle
Diameter is given as d = 15 fm
So radius
Potential energy is given by
From energy conservation
Answer: Technician B is right.
Explanation:
Evacuation process is used in refrigeration systems to remove moisture, air and non-profit condensable gases in order to achieve maximum function of the system.
vacuum pump is used to draw the sealed AC system into a vacuum. Evacuation of a refrigerant system also helps to maintain pressure, this is so as pulling a vacuum on the system is simply removing matter (mostly air and nitrogen) from inside the system so that the pressure inside drops below atmospheric pressure.
so as this ant moves
5 cm every second you multiply 5 by 120 (60 per minute as there are 60 seconds in a minute)
this is 600 cm
or
6 meters
i thinkits an instrument called seismograph. not sure
