What is the density of a grape?
The density of a grape can vary depending on the specific type and size of the grape. On average, the density of a grape is around 0.79-1.04 g/cm³. To calculate the density of a grape, you would measure its mass using a scale and then divide that by its volume, which can be determined by measuring its displacement in a graduated cylinder filled with water.
What term defined as the size of the association between two variables independent of the sample size?
There is no such term. The regression (or correlation) coefficient changes as the sample size increases - towards its "true" value. There is no measure of association that is independent of sample size.
What is meant by optical density equals 1?
It means that the speed of light in that medium is the same as in vacuum. This is ALMOST the case for stuff like "air". If you measure closely enough, it is only true for vacuum, all other materials have an optical density > 1.
True or false a balance can be used to measure volume?
True. A balance IS used to measure the volume of things.
Coefficient of variation is a measure of relative variation. True or False?
True
Can scientists use the measure of density to tell if something will float. False True?
True. Scientists can use the measure of density to determine if an object will float or sink in a fluid. If the density of an object is less than that of the fluid, it will float; if the density is greater, it will sink.
What is a way to determine the density of air?
Get all the air out of it, and weight it. This is the true weight of just the vacuum chamber.
How can graphing be helped used to help measure density?
Graphing is used in measuring density. It plots the temperature and density as read, and gives the true density at standard conditions.
True or false Density is the weight per volume of a substance?
False. Density is actually the mass per unit volume of a substance, not weight.
Is it true that when the weight of an object is less than the density of water that object the object will float?
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
All objects near the Earth's surface regardless of size and weight have the same force of gravity acting on them True or false?
True. All objects near the Earth's surface experience the same acceleration due to gravity, approximately 9.81 m/s^2, regardless of their size or weight. This is a fundamental principle of physics known as the equivalence principle.
What is the density of a textbook?
The easiest way to find the mass is to weigh it (not absolutely strictly true but OK). Then measure its height width and breadth. Multiply these together to get the volume. The density is the mass/volume. Try to keep in consisten units. Do all the measurements in cm and get the mass in grams and the density will be in g/cm3
Is this true does density is weight per unit volume?
Density can be defined that way, but it is more common to use another kind of density: mass per unit volume.
True or False muscular endurance decreases muscular strength bone density muscle size and muscle density?
False it increases them!!!!
The density of the substance is the same for all samples of the substance true or false?
Any sample size of a particular substance will have the same density.
Is it true that if you roll out your lungs they can measure to the size of a tennis court?
Yes, they can measure to the size of a tennis court.No, it is not. It is only about the size of a small hotel bathroom floor, not including the tub.
