How can you use the density of an object to predict whether it will sink or float?

Answers

Answer:

Explanation:

If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.

Closed series circuit

A closed series circuit is characterized with having a smooth and running path in which electric current flows .In this type of circuit there is no breakage found and is the same as the example provided above.

The open circuit usually has one or more forms of breakage which hinders the smooth flow of electric current and makes it less functional.

effort distance [e.d.]=1.5m

load [l]=500N

effort[E]=?

we have

load ×load distance =effort ×effort distance

500N×0.5=effort ×1.5

effort =250/1.5=166.67N

Answer:

1. The Speed is 390

2. The Frequency is 425 Hz

3. The Wavelength is 1.3

Explanation:

1. To find the speed of a wave you have to do the formula of speed.

Speed = Wavelength x Wave Frequency.

Speed = 1.5 * 260

= 390

2.

Formula

F= [tex]\frac{1}{T}\\[/tex]

F = 340 / 0.8

= 425

3.

Formula

Wavelength = speed / frequency

Wavelength = 440 / 344   (rounded to nearest tenth if necessary)

= 1.3

Answer:1. The Speed is 390

2. The Frequency is 425 Hz

3. The Wavelength is 1.3

Explanation:

1. To find the speed of a wave you have to do the formula of speed.

Speed = Wavelength x Wave Frequency.

Speed = 1.5 * 260

Which characteristics is common to the four outer planets in out solar system ?
A. Low Mass
B. Gaseous Composition
C. High density
D. Fast Revolution

Answers

Gaseous Composition is a common characteristic of the four outer planets in our solar system. So the correct answer is B. Gaseous Composition.

What are outer planets?

The four outer planets in our solar system are Jupiter, Saturn, Uranus, and Neptune, and they are often referred to as gas giants because they are composed primarily of hydrogen and helium gas. These planets have relatively low densities compared to the inner, rocky planets such as Earth, which have high densities due to their solid composition.

A. Low Mass is not a common characteristic of the four outer planets as Jupiter, the largest of the four, has a mass more than twice that of all the other planets in our solar system combined.

B. Gaseous Composition is a common characteristic of the four outer planets in our solar system.

C. High Density is not a common characteristic of the four outer planets as they have relatively low densities compared to the inner, rocky planets.

D. Fast Revolution is not a common characteristic of the four outer planets as Uranus and Neptune have longer revolution periods than Jupiter and Saturn.

Therefore, the correct answer is B. Gaseous Composition.
