What else can I help you with?
If you twang a ruler far away from the table will the sound be higher or lower?
When you twang a ruler close to the table there is less vibration so the sound is higher, when you twang it farther away there is more vibration so the sound is lower.Do double check just test for yourself.
What prediction did the students use to test their hypothesis?
The students used the prediction that if they gave plants different amounts of water, then the plants receiving more water would grow taller and healthier compared to the plants receiving less water.
What property does sinking and floating test?
The sinking and floating test helps determine the density and buoyancy of an object. Objects that are denser than the surrounding liquid will sink, while objects that are less dense will float.
How would you know if something would float on water?
Compare the density of the object in question to the density of water. If its density is less than water, it will float. For example, oak floats because its density is 0.7 g/cm³ and the density of water is 1 g/cm.If the density of an object is greater than water, it will sink.
What does it mean if an egg floats in water and how can this be used to determine its freshness?
If an egg floats in water, it means that it is not fresh. This is because as eggs age, air enters the egg through the porous shell, causing it to become less dense and float. Fresh eggs sink to the bottom of the water because they have less air inside. This simple test can be used to determine the freshness of an egg before cracking it open.
Can you demonstrate the higher or lower pitch test for me?
To demonstrate the higher or lower pitch test, listen to two sounds and determine which one is higher or lower in pitch.
Why does water heat up quicker in smaller test tube than bigger?
Water heats up quicker in a smaller test tube than in a bigger one primarily due to the surface area-to-volume ratio. In smaller test tubes, the ratio is higher, allowing more of the water's surface to be exposed to the heat source, leading to more efficient heat transfer. Additionally, less water in a smaller test tube means there is less mass to heat, which results in a faster increase in temperature.
How does a persons metabolism affect a THC drug test?
The higher the metabolism the less likely of a chance they won't find thc. I'd also recommend drinking about a gallon of water every day 3-4 days before the drug test. The more water the less likely they'll find thc. If you quit weed 4 days before the test and drink 4 gallons of water, you'll have a 90% chance of passing the drug test without the metabolism even factored in.
What does it mean if your urine test comes back abnormal?
Means you have more or less water in your body darker urine means less water and less vitams and minerals
How do you test the porosity of a soil?
To test the porosity of a soil, you can conduct a simple experiment called the water infiltration test. Dig a hole in the soil, pour a measured amount of water into the hole, and then measure the time it takes for the water to infiltrate into the soil. The faster the water infiltrates, the higher the porosity of the soil.
How do you test for brine?
To test for brine, you can use a simple conductivity test, as brine (a solution of salt in water) conducts electricity due to the presence of dissolved ions. Alternatively, you can perform a taste test, though this is less scientific, or use a hydrometer to measure the density of the solution; higher densities indicate higher salt concentrations. Another method involves adding silver nitrate, which will produce a white precipitate (silver chloride) if chloride ions are present, confirming the presence of brine.
Which will produce a higher initial rate of carbon dioxide production in a test tube 5ml of corn syrup 10ml of yeast and 5ml of water or 10ml of corn syrup 10ml of yeast and 0ml of water?
The test tube with 10ml of corn syrup, 10ml of yeast, and 0ml of water will likely produce a higher initial rate of carbon dioxide production. This is because the increased concentration of corn syrup provides more sugars for the yeast to ferment, leading to greater CO2 output. The absence of water in this scenario may limit fermentation efficiency, but the higher sugar content compensates for it. In contrast, the first mixture, while having water, has less fermentable substrate available.
What is the simple physical test to show that a sample of water is pure?
A scientific test you do on water similar to a chemical test
How does ct scan pitch works?
The new CT scanners move the patient while the picture is being made. The pitch is a ratio of the speed of movement to the rotation of the machine around the patient. (the rotation of the machine is inside the cover and only seen thru the small openings). A higher pitch gives a faster scan but the images may be less detailed. A lower pitch gives a more detailed image but takes longer to acquire. This is all figured by the technologist to acquire the best image for the test being performed.
What is the the format for writing the hypothesis?
it's what you believe the result of the test/experiment will be. e.g. oil is less dense than water.
What happens when you blow over the mouth of a test tube which is half filled with water?
Blowing over the mouth of the test tube will create a decrease in air pressure inside the tube. This decrease in pressure will cause the water in the test tube to rise up due to the higher pressure outside the tube. Ultimately, the water level in the test tube will rise as a result of the change in pressure.
What happens when oil is poured in to u- bend test tube of water?
When oil is poured into a u-tube test tube of water, the oil will separate from the water due to their difference in density. The oil, being less dense, will float on top of the water, creating two distinct layers. This is because oil is hydrophobic and does not mix with water.
