You can describe the _______________ of an object by saying it is moving in a straight line or is curved around another object.

You can also describe where an object is by its _______________ in relation to another object. The second object acts as a _______________ point. When an object changes position, you know it has motion. Motion can also be described by finding an object's _______________, or how fast or slow it moves in a certain amount of time. In addition, you can describe the object's speed AND direction together. This is called _______________.

Answer:

You can describe the<u> motion </u>of an object by saying it is moving in a straight line or is curved around another object. You can also describe where an object is by its <u> position </u> in relation to another object. The second object acts as a<u> reference</u> point. When an object changes position, you know it has motion. Motion can also be described by finding an object's <u>speed  </u>or how fast or slow it moves in a certain amount of time. In addition, you can describe the object's speed AND direction together. This is called <u>velocity</u>

Explanation:

In the given answer-

<u>Motion</u> is defined as - the change in the movement or position of any object  or body.

<u>Position</u> is said to be a place or somewhere or a location where any object or body is particularly placed/located or put on.

<u>Reference poin</u>t is a fixed point with regards to which any object or body changes its position. It is also called reference origin.

<u>Speed</u> is defined as the rate of any object covering certain distances. It is a scaler quantity (quantity which depends upon only magnitude).

<u>Velocity</u> is defined as the rate of speed per unit time. It is a vector quantity (quantity depending upon both magnitude and direction ).

If the acceleration is constant, and the starting velocity is zero, the relationship between the acceleration of a falling body (a), the time it takes to fall (t), and instantaneous velocity when it hits the ground (v) is:

the general equation of acceleration is:

vf = vi + at

assuming the initial velocity (vi) is zero, the equation becomes:

vf = at 

v = at

How are both chemistry and physics related to geoscience?
Yanka [14]

Answer:

Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical and chemical constitution of the Earth and its atmosphere. Earth science can be considered to be a branch of planetary science, but with a much older history. Earth science encompasses four main branches of study, the lithosphere, the hydrosphere, the atmosphere, and the biosphere, each of which is further broken down into more specialized fields.

There are both reductionist and holistic approaches to Earth sciences. It is also the study of Earth and its neighbors in space. Some Earth scientists use their knowledge of the planet to locate and develop energy and mineral resources. Others study the impact of human activity on Earth's environment, and design methods to protect the planet. Some use their knowledge about earth processes such as volcanoes, earthquakes, and hurricanes to plan communities that will not expose people to these dangerous events.

The Earth sciences can include the study of geology, the lithosphere, and the large-scale structure of the Earth's interior, as well as the atmosphere, hydrosphere, and biosphere. Typically, Earth scientists use tools from geology, chronology, physics, chemistry, geography, biology, and mathematics to build a quantitative understanding of how the Earth works and evolves. Earth science affects our everyday lives. For example, meteorologists study the weather and watch for dangerous storms. Hydrologists study water and warn of floods. Seismologists study earthquakes and try to understand where they will strike. Geologists study rocks and help to locate useful minerals. Earth scientists often work in the field—perhaps climbing mountains, exploring the seabed, crawling through caves, or wading in swamps. They measure and collect samples (such as rocks or river water), then they record their findings on charts and maps.

Hercules X-1 is a pulsating X-ray source. The X-rays from this source sometimes completely disappear for 6 hours every 1.7 days
Brut [27]

Answer:

06 Hours

Explanation:

As per the details given in the question it self, the neutron star X-1 is revolving around its companion star. The orbital period is 1.7 years which means it will complete the revolution in 1.7 years. During the movement in the orbit we will be able to detect the x-rays except for the time when it goes behind the companion star and eclipsed by it as seen from Earth.

Since the x-rays disappear completely for around 6 hours. This clearly means that eclipse period is 06 hours.

An 8-bit ADC has a digital resolution of %.
Mekhanik [1.2K]

Answer:

0.39 %

Explanation:

We have given 8 bit ADC and we have to find the resolution of the ADC

The resolution of the ADC is given by resolution=\frac{1}{2^n-1} where n is the number of bit

Here in question we have given 8 bit ADC so n = 8

So resolution is given by resolution=\frac{1}{2^n-1}=\frac{1}{2^8-1}=\frac{1}{255}=0.003921 =0.39%

Distinguish between refraction and diffraction
Anastaziya [24]

Refraction is the change in direction of waves that occurs when waves travel from one medium to another. It is always accompanied by a wavelength and speed of change. Diffraction is the bending of waves around obstacles and openings.
