The one that is not a name given for the four outer planets terrestrial planets. The correct option is 3.
What are Terrestrial planets?The planets Mercury, Venus, Earth, and Mars are referred to as terrestrial because their surfaces are compact and rocky, similar to Earth's terra firma. The terrestrial planets are the solar system's four innermost planets.
A terrestrial planet, telluric planet, or rocky planet is one that is primarily composed of silicate rocks or metals.
Mercury, Venus, Earth, and Mars are the inner planets in the Solar System that are closest to the Sun and are classified as terrestrial planets by the International Astronomical Union.
Astronomers who use the geophysical definition of a planet may consider two or three planetary-mass satellites, including the Earth's Moon, Io, and occasionally Europa, as terrestrial planets, along with the rocky protoplanet-asteroids Pallas and Vesta.
Thus, the correct option is 3.

5. A guava with a mass of 0.200 kg has a weight of
A. 0.200 N
B. 1.96 N
C. 4.50 N
D. 10.0 N
A guava with a mass of 0.200 kg has a weight of 1.96N
HOW TO CALCULATE WEIGHT:
The weight of an object is its mass with respect to gravity. That is, the weight of an object, which is a force measured in Newton (N) can be calculated as follows:F = mass (m) × acceleration due to gravity (a)
The mass of the guava in this question is given as 0.200kg, hence, the weight is calculated as follows:F = 0.200g × 9.8m/s²
F = 1.96N
Hence, a guava with a mass of 0.200 kg has a weight of 1.96N.

An atom with the electron configuration 2-8-8-2 has an incomplete
Answer:
3rd principal energy level
Explanation:
Principle energy that explains the energy of the electrons and positions of electrons of a particular atom. There are four energy levels fist to fourth that are made of sublevels and that is made up of s, p, d and f orbitals.
First principal energy level - 2
Second principal energy level - 8
Third principal energy level - 18
Fourth principal energy level - 32
3rd energy level has 9 orbitals, which has 18 electrons
2 in the s orbital,
6 in the three p orbitals, and
10 in the five d orbitals.
So, here there are only 8 electrons in the third principal energy level.

7. 70283.2g
8. 137.16metres
9. 4.968miles
10. 3.105miles
Explanation:
1. 1000mg = 1g
345.7 mg = 345.7/1000
= 0.3457g
2. 1kL = 1000000mL
0.00765 kL = 0.00765 × 1000000
= 7650mL
3. 1 day = 86400s
2.5 days = 2.5 × 86400
= 216000 seconds
4. 1 week = 10080minutes
1.000weeks is equivalent to 1 week, hence there are 10080minutes in 1.000week.
5. 1minute = 60seconds
40.0minutes = 40 × 60

1 oz = 28.34 g
2480oz = 2480 × 28.34
= 70283.2g
8. 1 foot = 12 inches
450 feet = 450 × 12
= 5400inches
1 inch = 0.0254metres
5400 inches = 5400 × 0.0254
137.16metres
9. 1 metre = 0.000621 mile
8000 metres = 8000 × 0.000621
= 4.968miles
10. 1 kilometers = 1000 metres
5km = 5 × 1000

= 3.105miles
You are using a calorimeter to calculate the specific heat capacity of a metallic ore. The calorimeter contains 0.50 kilograms of water at room temperature (22 °C). We heat the ore in boiling water and then drop the metal into the calorimeter and wait for the water and metal to reach the same temperature. The mass of the ore is 3.5 kilograms. We find that the water has increased in temperature to 24.3 °C. Recall that the specific heat of water is 4.18 J/g–°C. Calculate the specific heat capacity of the ore.
In the calorimeter, the heat received is the same as the heat released
Q abs = Q release
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
Q released by a metallic ore and absorbed by water at calorimeter
Q ore = Q water
Q waterm = 0.5 kg = 500 g
c = 4.18 J/g–°C.
Δt = 24.3 - 22 = 2.3
[tex]\tt Q=m.c.\Delta t\\\\Q=500\times 4.18\times 2.3=4807~J[/tex]
the specific heat capacity of the ore.Q ore = Q water = 4807 J
m ore = 3.5 kg = 3500 g
Δt = 100 - 24.3 = 75.7

A scientist is examining a mixture of nitrogen, hydrogen, and ammonia. The individual pressures that are exerted by nitrogen and hydrogen are 0.26 atm and 0.28 atm, respectively. If the total pressure is 0.90 atm, what is the partial pressure of ammonia? Use P subscript T equals P subscript 1 plus P subscript 2 plus P subscript 3 plus ellipses plus P subscript n.. 0.27 atm 0.36 atm 0.54 atm 0.90 atm
Answer: 0.36 atm
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
[tex]p_{total}=p_1+p_2+p_3[/tex]
Given : [tex]p_{total}[/tex] = total pressure of gases = 0.90 atm
[tex]p_{N_2}[/tex]= partial pressure of nitrogen = 0.26 atm
[tex]p_{H_2}[/tex] = partial pressure of hydrogen = 0.28 atm
[tex]p_{NH_3}[/tex]= partial pressure of ammonia = ?
putting in the values we get:
[tex]0.90=0.26 +0.28+p_{NH_3}[/tex]
[tex]p_{NH_3}=0.36atm[/tex]
Thus the partial pressure of ammonia is 0.36 atm
Answer:
B) 0.36 atm

Scientific notation is a way to express numbers in a form that makes numbers that are too small or too large more convenient to write. It is commonly used in mathematics, engineering, and science, as it can help simplify arithmetic operations. In scientific notation, numbers are written as a base, b, referred to as the significant, multiplied by 10 raised to an integer exponent, n, which is referred to as the order of magnitude:

The charged particles in the beams that Thomson studied came from atoms. As these particles moved away from their original atoms, they formed a visible beam. The current model of the atom includes protons, neutrons, and electrons. What is the best use of an atomic model to explain the charge of the particles in Thomson's beams? An atom's negative particles are surrounded by positive matter, so the positive particles are easier to remove. An atom's positive particles are surrounded by negative matter, so the negative particles are easier to remove. An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove. An atom's larger positive particles are at a distance from the central negative particles, so the positive particles are easier to remove.
Answer:An atom's positive particles are surrounded by negative matter, so the negative particles are easier to remove.
Explanation:
From our knowledge of the atom, we know that the nucleus lies at the center of the atom. The nucleus is positively charged because it contains the positive particles in the atom
The negative matter (electrons) surround the positive matter (protons) hence it is easier to remove the negative particles compared to the positive particles.

What is the mass of an object with a density of 5.7 g/cm^3 and a volume of 48
cm^3? *
Answer:
273.6 g
Explanation:
mass =(density)(volume)
mass=(5.7g/cm^3 )(48 cm^3)
cancel out your cm^3 and your are left with grams
multiply (5.7g)(48)=273.6 g
The mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.
What is density?Density is defined as the degree to which a material is packed together.
It is also defined as a mass per unit volume of the substance.
Its SI unit is kilogram per cubic meter or gram per meter.
Density can be expressed as
Density = mass / volume
Mass = density x volume
As given, Density = 5.7 g/cm³
Volume = 48 cm³
So, Mass = 5.7 g/cm³ x 48 cm³
= 273.6 grams
Thus, the mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.
