How do I know if my photo tube is bad?

How do I know if my photo tube is bad? HOW TO IDENTIFY WHEN YOUR TV PICTURE TUBE IS BAD. Look for blurry areas on the TV screen when it’s on. These may appear as circular bluish-green spots or as a large spot. This is a warning that a magnetic disturbance has affected the picture […]

What motion is illustrated by a ball thrown horizontally?

What motion is illustrated by a ball thrown horizontally? Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola. What are the standard assumptions we make for horizontally launched projectiles? Assumptions […]

What are the three main physical properties of sound waves?

What are the three main physical properties of sound waves? Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. […]

What is a disadvantage of using nuclear power?

What is a disadvantage of using nuclear power? Disadvantages of Nuclear Power The further implementations of nuclear power are limited because although nuclear energy does not produce CO2 the way fossil fuels do, there is still a toxic byproduct produced from uranium-fueled nuclear cycles: radioactive fission waste.
