The density of lead is 11.3 g/cm3. what mass of lead is required to make a 1.00 cm3 fishing sinker?

Physics

Elza [17]2 years ago

The mass of lead required to make a 1.00 cm3 fishing sinker is 11.3g.

What is mass?

Mass is a metric used in physics to express inertia, a fundamental characteristic of all matter. A mass of matter's resistance to altering its direction or speed in response to the application of a force is what it essentially is. The change that an applied force produces is smaller the more mass a body has.

Given :

Density of lead = 11.3 g/cm3

Volume of  sinker  =  1.00 cm3

One of a substance's attributes is density, which is calculated by dividing the mass by the volume. Mathematically:

Density : Mass / volume

therefore after putting the values,

mass= 11.3g

Which step of the scientific method is the scientist using? "This paper details my results on how dolphins use sonar to navigate
Kazeer [188]

The step of the scientific method with the information "This paper details my results on how dolphins use sonar to navigate." is: D. Report Results​.

Science can be defined as a branch of intellectual and practical study that systematically observes a body of fact with respect to the structure and behavior of both living and non-living organisms in the natural world through experiments.

Some of the steps (activities or actions) that a scientist performs (carries out) while using a scientific method include the following:

  • Analyze data and draw conclusions.
  • Observation.
  • Experimentation.
  • Report results.

The results of an experiment provide the necessary data and information about the specimen which was used in the course of conducting an experiment.

Hence, a report result would convey these information to the user (reader) of scientific method proposed by a scientist.

In conclusion, a paper which details the results on how dolphins use sonar to navigate is considered a report of the results.

A 6.00 kg ball is dropped from a height of 12.0 m above one end of a uniform bar that pivots at its center. The bar has mass 5.0
Andre45 [30]

Answer:

The height of the other ball go after the collision is 2.304 m.

Explanation:

Given that,

Mass of ball = 6.00 kg

Height = 12.0 m

Mass of bar =5.00 kg

Length = 4.00 m

Suppose we need to calculate how high will the other ball go after the collision

We need to calculate the velocity of ball

Using formula of velocity

v=\sqrt{2gh}

v=\sqrt{2\times9.8\times12.0}

v=15.33\ m/s

We need to calculate the angular momentum

Using formula of angular momentum

l_{before}=mvr

Put the value into the formula

l_{before}=6.00\times15.33\times2.0

l_{before}=183.96\ kgm^2/s

We need to calculate the angular momentum

Using formula of angular momentum

l_{after}=I_{t}\omega

l_{after}=(\dfrac{ml^2}{12}+m_{1}r^2+m_{2}r^2)\omega

Put the value into the formula

l_{after}=(\dfrac{5\times4.00^2}{12}+6.00\times2.0^2+6.00\times2.0^2)\omega

183.96=54.66\omega

\omega=\dfrac{183.96}{54.66}

\omega=3.36\ rad/sec

After collision the ball leaves with velocity

We need to calculate the velocity after collision

Using formula of the velocity

v= r\omega

v=2.0\times3.36

v=6.72\ m/s

We need to calculate the height

Using formula of height

h=\dfrac{v^2}{2g}

Put the value into the formula

h=\dfrac{(6.72)^2}{2\times9.8}

h=2.304\ m

Hence, The height of the other ball go after the collision is 2.304 m.

If an X-ray tube is operating at a current of 30.0 mA:a) How many electrons are striking the target per second? b) If the potent
Zina [86]

Answer:

Explanation:

A. Q= It

30E-3A=q

Ne = q

30E-3/1.6*10-19= N

N= 1.8*10^16 electrons

B. Power= I x v

= 30*10^-3A x 100*10^3v

= 3000watts
