Which type of microscope can magnify objects up to a million times?
an electron microscope can magnify something up to 500,000 times
Do protons and Electrons have about the same mass?
No. Protons have about 1836 times the mass of an electron.
Which has a greater mass an electron or a proton?
In kilograms, an electron's mass is ~9 x 10^(-31). A proton's mass is ~1.7 x 10^(-27). The mass of the proton is more than 1000 times of an electron.
Why does a high pitched sound come when the TV is put on?
The spot that draws the picture on the TV screen sweeps across the screen 15,750 times every second. At the same time, it's sweeping from top to bottom of the screen 60 times every second. In that way, it draws the picture as a stack of horizontal lines on the screen. The spot is the front end of a beam of electrons that shoot at the screen from the rear of the picture tube. It gets steered around by electromagnetic coils around the neck of the picture tube. The coils are driven by voltages produced in the electronics of the TV set. The high-pitched sound you hear is the 15.75 KHz alternating voltage that sweeps the beam side to side across the screen.
What is 1800 times the mass of an electron?
hydrogen
Where are the Easter eggs hidden on Howrse?
they fly across your screen at random times at random places. you have to click them
What do you do if switch-in MMO comes up with a black screen?
You click in the middle a million times and click around the screen and the normal blue screen to allow you to customize, buy coins, or go to your house should appear. Hope I helped!
How many times can an electron microscope magnify?
what magnification is electron microscope capable of
How many times lighter is an electron than a proton?
The mass of an electron is approximately 1⁄1836 of a proton. Thus as hydrogen is made of one proton and one electron, hydrogen is 1837 times heavier than an electron.
How do black capped chickadees fly?
The Black-Capped Chickadee is a tiny round bird. The Black-Capped Chickadee likes to fly in groups and can many times be seen flying across open fields.
Which type of microscope can magnify objects up to a million times?
an electron microscope can magnify something up to 500,000 times
How dark can a mine be?
It's always dark, but there is always a tiny bit of light. The screen cannot be completely black, but at times, it seems like it.
How small is a electron?
An electron is 1836 times smaller then a proton.The mass of an electron is 9,10938291(40)×10−31 kg.
Do a neutron and an electron have approximately the same mass?
No, a neutron is about 1836 times the mass of an electron
Do protons and Electrons have about the same mass?
No. Protons have about 1836 times the mass of an electron.
How does a television control the electron beam that is continuslly scanned across and down the screen?
it uses four electromagnets, two for up and down and two for right ang left. these electromagnets increase and decrease power between them to move the electron beam around. depending on which electromagnet has how much power the electron beam will move towards it at that amount, upper magnet for how high the right magnet for right left for left down for down, i thing they all have to be on at all times to balance the beam with the the magnet opposeing its direction. the electromagnet is around a circle ferrite core in front of the electrongun. the electromagnets change their power ratio between each other thouands of times a second i think
