How long do lead aprons last?
How long do lead aprons last? 10 years How often should lead aprons be checked? Lead aprons should be checked fluoroscopically at least on an annual basis for their shielding integrity. Rejecting an apron depends on the location, area size and number of flaws. It is best to keep the number of flaws to a […]
What is the biggest type of cloud?
What is the biggest type of cloud? Cirrus clouds What are the 5 main types of clouds? Ten Basic Clouds Cirrus (Ci), Cirrocumulus (Cc), and Cirrostratus (Cs) are high level clouds. Altocumulus (Ac), Altostratus (As), and Nimbostratus (Ns) are mid-level clouds They are composed primarily of water droplets. Cumulus (Cu), Stratocumulus (Sc), Stratus (St), and […]
What is the difference between a clutch and a torque converter?
What is the difference between a clutch and a torque converter? The way a torque converter operates compared to a clutch is very different. The main difference is that torque converters idle before they engage and they start to engage at around 1,700 RPM. While clutches engage earlier, they have a slip range at about […]
What is energy of activation for the enzymes?
What is energy of activation for the enzymes? Lesson Summary The activation energy is the energy required to start a reaction. Enzymes are proteins that bind to a molecule, or substrate, to modify it and lower the energy required to make it react. Why is it important that enzymes lower the activation energy? Enzymes are […]
Are water slides dangerous?
Are water slides dangerous? Water slides are the number one cause of injuries at water parks. So, follow ride directions. Rules like “feet first” are there for a reason―to keep riders safe. Can you fall out of a water slide? It’s the water running down the slide, creating an almost frictionless surface, that makes this […]
How do you calculate the area of a Venturi meter?
Which graph is used to show change in a given variable?
Which graph is used to show change in a given variable? line graph What are variables in a chart? Variables control charts are used to evaluate variation in a process where the measurement is a variable–i.e. the variable can be measured on a continuous scale (e.g. height, weight, length, concentration). Which graph would be best […]
What element is shiny ductile and conducts heat well?
What element is shiny ductile and conducts heat well? Metals What type of elements are poor conductors of heat and electricity? Nonmetals are poor conductors of heat and electricity, because electrons are not free to move. Nonmetals are found to the right of the stair-step line, except for hydrogen which is in group 1. Group […]
