## How do you find the mass of displaced water?

The mass of the displaced fluid can be expressed in terms of the density and its volume, m = ρV. The fluid displaced has a weight W = mg, where g is acceleration due to gravity. Therefore, the weight of the displaced fluid can be expressed as W = ρVg.

## How do you think the mass of the boat will relate to the amount of displaced liquid?

(Note: The mass of the displaced liquid is equal to the volume of the liquid multiplied by its density.) 10. Analyze: In the first part of this activity, you discovered that when a boat is placed in water, the volume of displaced water is equal to the mass of the boat.

## How do you find the volume of water displaced by an object?

Instead, the volume of the rod equals the amount that the water went up in the graduated cylinder (the amount displaced). To find the amount of water displaced, students should subtract the initial level of the water (60 mL) from the final level of the water.

## Can you use mass and volume to predict whether an object will sink or float in water?

Can mass alone be used to accurately predict whether an object will sink or float? -No, you need both mass and volume to determine its desity to see if it can float. -No, you need both mass and volume to find its density to see if it can float.

## Does a higher density float or sink?

Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.

## Does volume alone determine whether an object will sink or float explain?

Volume is not alone when determining whether an object will float or sink. An example would be object 3 with 4.0 grams and 5.0 mL. Calculate: The densityof an object is its mass per unit of volume. Dense objects feel very heavy for their size, while objects with low density feel very light for their size.

## What is the difference between the mass of an object and its volume?

Mass measures the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg). Volume measures the amount of space that a substance or an object takes up.

## What are the 3 types of buoyancy?

The three types of buoyancy are positive buoyancy, negative buoyancy, and neutral buoyancy. Positive buoyancy is when the immersed object is lighter than the fluid displaced and this is the reason why the object floats.

## What is true of the mass and volume of floating objects?

What is true of the mass and volume of all the floating objects? The volume was more than the mass of each object. Dense objects feel very heavy for their size, while objects with low density feel very light for their size. To calculate an object’s density, divide its mass by its volume.

## How do you calculate true mass?

So we have m minus m times density air divided by density aluminum equals m prime and then factor out the m here and then divide both sides by this bracket and you get the true mass is the apparent mass divided by 1 minus density of air divided by density of aluminum.

## Why do objects float?

An object floats when the weight force on the object is balanced by the upward push of the water on the object. Many objects that are hollow (and so generally contain air) float because the hollow sections increase the volume of the object (and so the upwards push) for very little increase in weight force down.

## Does Saturn float on water?

Saturn could float in water because it is mostly made of gas. Saturn spins on its axis very fast. A day on Saturn is 10 hours and 14 minutes. The Ringed Planet is so far away from the Sun that it receives much less sunlight than we do here on Earth.

## What is the heaviest planet?

Fifth in line from the Sun, Jupiter is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined.

## What is the smallest star in the universe?

The smallest known star right now is OGLE-TR-122b, a red dwarf star that’s part of a binary stellar system. This red dwarf the smallest star to ever have its radius accurately measured; 0.12 solar radii.

## What star is the coldest?

It is true as a Penn State University astronomer using NASA’s Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescopes has discovered a “brown dwarf” star that appears to be the coldest of its kind. The star has been named WISE J085510. 83-071442.5.

## What type of visible star is coolest?

A red dwarf is the smallest and coolest kind of star on the main sequence. Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighborhood of the Sun, but because of their low luminosity, individual red dwarfs cannot be easily observed.

## Which is hotter red star or blue star?

Humans at 300 Kelvin degrees emit in the infrared. Then a blue star is HOTTER than a RED star. The temperature of a blue star is 40000 Kelvin degrees, the temperature of a red star is 3500 Kelvin.

## What is the name of the coolest star?

According to a new study, a star discovered 75 light-years away is no warmer than a freshly brewed cup of coffee. Dubbed CFBDSIR 1458 10b, the star is what’s called a brown dwarf.

## Why is red light hotter than blue?

Red light has a longer wavelength than blue light; this means, blue light has a higher frequency than red light. Since there is more energy in higher frequencies, theoretically, blue light is warmer than red light. Since there is more energy in higher frequencies, theoretically, blue light is warmer than red light.
