Is the wave length measured from the crest to the trough true or false?
It is False.
Work is measured in joulestrue or false?
True.
Is it true that the temperature of an object is a measure of the average kinetic energy of the molecules in the objects?
FALSE (APEX)
When an object moves work has occurred true or false?
false
Work is measured in joules True or false?
true
A cylinder is a polyhedron?
A hexagonal cylinder is an impossible object. If you meant a hexagonal prism then it is a polyhedron.
When using a glass graduated cylinder partially filled with water always read the mark closest to the bottom of the meniscus true or false?
True
What is a measuring cylinder used to for?
A graduated cylinder is used to measure the volume of a liquid and occasionally a solid (it can be inverted and used to measure gas as well!) The cylinder is made of glass (usually Pyrex) or plastic and has measured lines with volume values noted on the lines (a.k.a. graduations.) Simply fill the cylinder with a liquid until it reaches the volume you require. When measuring the liquid level you will notice that electrostatic forces and gravity alter the shape of the liquid's surface to a crescent shape. This is called a "meniscus." In most cases the shape will look like a smile, you must make the measurement so the bottom portion of the smile shape is lined up with the graduation mark on the cylinder. Occasionally the meniscus will be close to flat or inverted like a frown, such is the case with liquid mercury. In such scenarios, the uppermost portion of the frown shape should be used for accurate measurement. To measure the volume of a small solid object of irregular shape, you can measure out a certain volume of a liquid (like water) in the cylinder, and then carefully place the solid objects in the cylinder, making sure they are completely submerged and contain no air bubbles. The water is displaced to a new reading on the graduated cylinder and the difference between the original and the final readings is the volume that the solid object occupies. Measuring the volume of a gas is more complicated to set up and explain. In general the graduated cylinder is filled with liquid and inverted in a large container filled with water. The gas reaction evolves gas through a tube, directly under the inverted cylinder, and rises to the top (the base of the inverted cylinder). The amount of gas produced will displace the water downward as it fills the top of the cylinder and can be measured using the graduations when the gas has ceased. This will give you the volume that the gas occupies. If the gas is soluble in the liquid, some may remain dissolved and give a false-low volume reading.
Is heat is measured in degrees Celsius?
Temperature is measured in celcius.Heat is measured in joules.
True or false- The volume of a gas cannot be measured?
false
When reading the volume of a liquid in the graduated cylinder or you must read from the bottom of the?
You must read from the bottom of the meniscus. In a narrow, graduated glass cylinder, water has a slightly domed surface, with the centre being higher than the side, so giving a false reading if the centre height is taken.
True or false an object that revolves around another object does not move?
false
The character Denise graduated from college on The Cosby Show?

Balanced forces acting on an object cause the object to accelerate True or false?
false
Is wave length is measured from crest to the trough?
False, it is measured from crest to crest.
The volume of a gas cannot be measured?
FALSE
