Answer:
b. craters, river valleys feeding into surface lakes of very cold liquids
Explanation:
- Jovian moons are the four largest satellites like the moon of the Jupiter ie the Lo, Europa, Ganymede, Callisto and were first seen by the galileo. They are amiugly the largest moons with radii larger than the dwarf planet.
- Lo has more than 400 active volcanoes and dotted more than 100 mountains and has an extremely thin atmosphere made up of sulfur dioxide. The Europa has deep oceans of liquid water, and the layer of ice, and are characteristic of the tidal heating.
- <u>While the surface of Callisto is heavily cratered and has salty liquid water.</u>
Answer:
R = 98304.75 m = 98.3 km
Explanation:
The density of an object is given as the ratio between the mass of that object and the volume occupied by that object.
Density = Mass/Volume
Now, it is given that the density of Earth has become:
Density = 1 x 10⁹ kg/m³
Mass = Mass of Earth (Constant) = 5.97 x 10²⁴ kg
Volume = 4/3πR³ (Volume of Sphere)
R = Radius of Earth = ?
Therefore,
1 x 10⁹ kg/m³ = (5.97 x 10²⁴ kg)/[4/3πR³]
4/3πR³ = (5.97 x 10²⁴ kg)/(1 x 10⁹ kg/m³)
R³ = (3/4)(5.97 x 10¹⁵ m³)/π
R = ∛[0.95 x 10¹⁵ m³]
<u>R = 98304.75 m = 98.3 km</u>
Saying english so we can help u
Answer:
The correct option is;
Biochemist → Archivist → Civil Engineer → Engineering Technician
Explanation:
1) Biochemist require the completion of a science degree or applied science degree, while biochemist usually hold a PhD to perform research independently, while entry level positions in the profession require a masters or bachelors degree
The PhDs usually require about 5 years to complete, after obtaining the masters degree
2) The general educational requirement to become an archivist is a master's degree in the fields of library science, history, public administration, political science, or archival science, which requires the completion of a bachelors degree followed by the completion of the masters degree which is thus 4 to 6 years
3) Civil engineer title is awarded to holders of a bachelors degree in Civil Engineering which gives the strong mathematical and science background required in the profession usually. The Civil Engineering program duration is five years
4) The engineering technician consist of 8.2% with masters degree, 42.0% have bachelors degree, while it is also possible to become an engineering technician with a GED or a high school degree
Therefore, the usual duration of study to become an engineering technician is two years of an associate degree program.
Answer:
a. mechanical; require a medium to travel through
Explanation:
Longitudinal, transverse and surface waves are types of mechanical waves. For example, within the longitudinal waves are the sound waves, which needs a medium to propagate like the air. This is why sound does not travel in a vacuum.
And an example of a transverse wave is the waves that form in the water when a rock is thrown (ripples), these waves need a medium (the water) to propagate.
On the other hand, electromagnetic waves such as light waves do not need a medium to propagate, this is why we can see the light of distant stars because their light travels through the vacuum until it reaches us.
So, the answer is:
Transverse, surface, and longitudinal waves are all mechanical waves because they require a medium to travel through .
