The amount of work done by the force of gravity on the ball is 4.41 Joules.

<u>Given the following data:</u>

  • Mass of ball = 0.180 kg.
  • Displacement = 2.5 meters.

<u>Scientific data:</u>

  • Acceleration due to gravity = 9.8 m/s^2.

To calculate the amount of work done by the force of gravity on the ball:

<h3>How to calculate work done.</h3>

In Science, work done is calculated by multiplying force and the height or displacement experienced by an object.

Mathematically, work done is given by the formula:

Work\;done = force \times displacement = mgh

Substituting the given parameters into the formula, we have;

Work\;done = 0.180 \times 9.8 \times 2.5

Work done = 4.41 Joules.

Which best describes a major characteristic of both volcanoes and earthquakes? they are centered at the poles?
Arturiano [62]
<span>A major characteristic of both volcanoes and earthquakes is that they are located in the same geographic area. Most earthquakes are along the edges of tectonic plates. This is where most volcanoes are too. Most earthquakes directly beneath a volcano are caused by the movement of magma.</span>

Usimov [2.4K]

Answer:

L= 12 light years

Explanation:

for length dilation we use the formula

L=L_0\sqrt{1-\frac{v^2}{c^2} }

now calculating Lo

Lo = 12.5×365×24×3600×3×10^8

= 1.183×10^17 m

now putting the values of v and Lo in the above equation we get

L=1.183\times10^{17}\sqrt{1-\frac{0.28c^2}{c^2} }

= 1.136×10^17 m

L=  = \frac{1.136\times10^{17}}{365\times24\times3600\times3\times10^8}m

so L= 12 light years

DIA [1.3K]

Answer:

The charges on the plates,

Explanation:

A capacitor is an electronic device that can be used for storing of charges. A parallel plate capacitor consists of two plates of equal area separated by a dielectric constant. The energy stored in the capacitor is in the form of potential energy which comes into play during the discharging process of the capacitor.

The energy stored depends majorly on the voltage, area of the plates, distance between the plates and the nature of the dielectric constant of the material between the plates. But it does not depend on the charges on the plates.

"State the process that divides one nucleus into two genetically identical nuclei"
kompoz [17]

Answer:

<em>Mitosis</em>

Explanation:

Mitosis: Mitosis is a cell or nuclear division following the duplicate of the chromosomes, whereby each daughter cell or nucleus has exactly the same chromosomes content as the parent. In other words, mitosis is a cell division in which daughter cells have the same number of chromosomes as the parent cell.

Mitosis takes place during organism's growth, development, and asexual reproduction. in plants mitosis takes place in the terminal bud of the shoot at the tip of the roots and shoots. In animal mitosis occur at growth centres which are everywhere.

Mitosis produce diploid number, in order word, the number of chromosomes in each somatic cell of an organism is called the diploid number (2n)

Example of mitosis is the multiplication of the skin covering a child's body during growth
