If you were to take a trip around the surface of one of the planets,

1 answer:

7 0

The time taken to take a trip around a planet depends on its size. Since Venus has almost the same size as the earth, it would take you about the same amount of time to take a trip round Venus as a trip around the Earth.

The solar system is composed of the planets; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.

All these planets move round the sun in their orbits. The planets vary in size.

However, Venus(7,926 miles) has almost the same size as the earth(7,521 miles).

The period of Venus is 243 earth days while the period of the earth is 365 earth days.

Hence, it would take you about the same amount of time to take a trip round Venus as a trip around the Earth.

Match the following family of elements to its group.

docker41 [41]

Explanation:

To solve this problem, we simply use the periodic table of elements which groups elements based on their atomic numbers.

The atomic number of an element is the number of protons it contains. The protons are the positively charged particles within an atom.

The vertical arrangement of elements on the periodic table is the group.
The horizontal arrangement of elements is the period.

Now;

Noble gases belongs to group 18

Alkali earth metals belongs to group 2

Halogens belongs to group 17

Alkali metals belongs to group 1

Transition metals belongs to group 3-12

An earthquake on the ocean floor produced a giant wave called a tsunami. The tsunami traveled through the ocean and hit a remote

Svetlanka [38]

Answer:

Yes

Explanation:

What cause an earthquake is when the earth plates shift and if theirs a drop in the tentonic plates a ripple effect like when you drop something in water will occur. The plates shift down the water in which the plate shift down the water will go in that direction due to gravity, but instead of equalizing the water will pick up some speed and velocity and begin to form a wave now. When an tsunami happens you know it coming cause the water moves back cause the water is picking up to much speed and due to cohesion its moves along with the move water and builds up. Creating a massive tidal wave known as tsunamis.

Sodium metal is sometimes used as a cooling agent in heat exchange units because of its relatively high molar heat capacity of 2

IgorC [24]

Answer:

The specific heat of sodium is 1,23J/g°C

Explanation:

Using the atomic weight of sodium (23g/mol) and the atomic weight definition, we have that each mole of the substance has 23 grams of sodium.

starting from this, we use the atomic weight of sodium to convert the units from J / mol ° C to J / g ° C

$28,2 \frac{J}{mol C} x \frac{1mol}{23g} = 1,23 J/g C$

Describe the double circulation system of the human body

Alika [10]

Answer:

we have two loops in our body in which blood circulates. One is oxygenated, meaning oxygen rich, and the other is deoxygenated, which means it has little to no oxygen, but a lot of carbon dioxide.
