An orange falls off of a display at a store and rolls 5 meters in 2.5 seconds. What is the average speed of the orange?
An orange falls off of a display at a store and rolls 5 meters in 2.5 seconds the average speed of the orange will be 2 meters per second.
What is speed?Speed if the rate of change of position of an object in a given time of interval or per unit time of interval and it is the ratio of distance traveled to the time taken and the unit will be meter per second.
The average speed of the orange will be if the orange falls off of a display at a store and rolls 5 meters in 2.5 seconds,
Speed = distance / time
Substituting the value,
speed =5 meters /2.5 seconds
speed = 2 meters per second.
Therefore, the average speed of the orange will be 2 meters per second if, the orange falls off of a display at a store and rolls 5 meters in 2.5 seconds.

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.

which of the following is not a name given for the four outer plantets
1. gas Giants
2. Jovian planets
3. Terrestrial planets
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.

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.
The heat required to raise the temperature of 12g of water from 16 C to 21 C is:
a) 60 J
b) 60 cal
c) 50 cal
d) 50 J
Answer:
The correct option is;
b) 60 cal
Explanation:
The mass of the given water, m = 12 g
The initial temperature of he given water = 16°C
The final temperature of the given water = 21°C
The specific heat capacity of water, c = 4.184 J/(g·°C) = 1 cal/(g·°C)
The amount of heat, ΔQ, required = Mass × Specific heat capacity × Change in temperature
ΔQ = 12 × 4.184 × (21 - 16) = 251.04 J
Similarly, we have;
ΔQ = 12 g × 1 cal/(g·°C) × (21 - 16)°C = 60 cal
The amount of heat required = 60 cal.

A large marble is dropped in a graduated cylinder with 45 mL of water in it. The water level increased to 61 mL. What is the volume of the marble?
Answer:
Volume of the marble is 16 ml.
Initial volume present in graduated cylinder=45 ml.
Final volume in graduated cylinder after marble is dropped=61 ml.
Volume of water displaced=volume displaced by marble.
Volume displaced by marble=final volume in cylinder-initial volume in cylinder
Volume displaced=61ml-45ml=16ml

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

figures.
Answer:
9.99L
Explanation:
you can see the answer at the pic
Answer:
The volume of aluminum is 9.99 cm³.
Explanation:
Given data:
Mass of aluminum = 26.98 g
Density of aluminum = 2.70 g/cm³
Volume of aluminum = ?
Solution:
Formula:
d = m/v
now we will put the values in formula.
2.70 g/cm³ = 26.98 g / v
v = 26.98 g / 2.70 g/cm³
v = 9.99 cm³
Thus, the volume of aluminum is 9.99 cm³.

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.

13) The scientist will have 6 grams of product as before but will have two grams of unreacted copper atoms because the mass ratio of copper to sulfur in this reaction is 2:1
Explanation:
12) Phosphorus trichloride has a trigonal pyramidal structure and is composed of three atoms of chlorine and one atom of phosphorus.
In the ball and stick model, an orange ball representing the phosphorus atom and three green balls representing chlorine atoms are connected by means of sticks that are coloured halfway green and orange respectively to represent the shared electrons between phosphorus and chlorine with the chlorine atoms forming the base of a triangular pyramid while the phosphorus atom forms the top of the pyramid.
13) The reaction between copper and sulfur to form copper sulfide is shown in the equation below:
Cu + S ---> CuS
1 mole of copper reacts with 1 mole of sulfur to produce 1 mole of copper sulfide
molar mass of copper = 64 g/mol; molar mass of sulfur = 32 g/mol, molar mass of copper sulfide = 96 g/mol
mass ratio of copper to sulfur = 63 g/ 34 g = 2
This means that 2 grams of copper will react with 1 g of sulfur to produce 3 grams of product. similarly, 4 g of copper will react with 2 g of sulfur to produce 6 grams of product.
Therefore 6 g of of copper will react with 3 g of sulfur. However, since the amount of sulfur available for reaction is 2 g only, 2 g of copper will be left unreacted after 4 g has reacted completely with 2 g of sulfur to produce 6 g of copper sulfide.
