The elements least likely to form bonds are found in which group?
O 15
O 16
017
O 18
The element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.
What is group 18 of the periodic table known?The elements of group 18 in the modern periodic table are known as noble gases. These gases are colorless, odorless, tasteless, and nonflammable under standard conditions.
They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.
Due to this fact, they would not have any ability to form bonds with other elements in order to produce compounds or molecules. They are the most stable elements because they have a full outer shell of valence electrons, so they have no need to bond with other elements.
Therefore, the element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.

A woman drives to her office 10 km away from her house at 9 am, and
reaches her office at 9:20 am. She stays in the office until 6 p.m, and
then returns home at 6:25 p.m. Which answer gives the correct
distance and displacement at 6:25 p.m.?
The displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.
The given parameters;
distance between the woman's house and her office, d = 10 kmtime to reach her office = 20 minutestime to return to her house = 25 minutesDisplacement is defined as the change in the position of an object. It can be described as 'how far' an object is displaced from the initial position.
The first position of the woman, x₁ = 10 km to officeThe final position of the woman, x₂ = 10 km back homeThe woman's displacement = x₂ - x₁ = 10 km - 10 km = 0
Distance is the total path covered by an object during motion.
Total distance of the woman at 6:25 pm = 10 km + 10 km = 20 km
Thus, we can conclude that the displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.

What aspect of motion can you conclude is common among freely falling objects ?
Answer:
Free-fall is defined as the movement where the only force acting on an object is the gravitational force.
By the second Newton's law, we have that:
F = m*a
Where F = Force, m = mass, a = acceleration.
We can write this as:
a = F/m
And the gravitational force can be written as:
F = (G*M/r^2)*m
Where G is the gravitational constant, M is the mass of the Earth in this case, and r is the distance between both objects (the center of the Earth and the free-falling object)
As the radius of the Earth is really big, the term inside the parentheses is almost constant in the region of interest, then we can write:
G*M/r^2 ≈ g
And the gravitational force is:
F = g*m
And by the second Newton's law we had:
a = F/m = (g*m)/m = g
a = g
Then the acceleration does not depend on the mass of the object.
Then the thing that is common among the free-falling objects is the vertical acceleration.
What is 50,000 in exponential notation?
Answer:
To write 50000 in scientific notation, we will have to move the decimal point four points to left, which literally means dividing by 104 . Hence in scientific notation 50000=5×104 (note that as we have moved decimal four points to left and thus divided by 104 , we are multiplying by 104 to compensate.
Explanation:
What happens to the acceleration of an object if the net force on it increases?
OA. The acceleration increases.
OB.
The acceleration decreases.
O C.
The acceleration becomes zero.
OD.
The acceleration remains the same.
Answer:

Explanation:
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased
1. Why are the speed values in the data table called "average" instead of "instantaneous"?
Answer:
The speeds are called average because they are a calculation of a course of distance divided by a duration of time.
Explanation: Instantaneous speed is when the speed is instant for instance when driving a car and if you would want to check how fast that you are moving you would instantly look at the speedometer that is what we call instantaneous speed
A block has two forces on it. One force is 15 N going north and the other is 22 N going east. What is the overall force pushing on the block with magnitude and direction?
Answer:
The overall force pushing on the block is 26.63 N in the direction of N 34° E
Explanation:
Given;
force going north, F₁ = 15 N
force going east, F₂ = 22 N
The resultant of the two forces is the hypotenuse side of the right angled triangle formed by the two forces.
Let the magnitude of the resultant force = F
F² = F₁² + F₂²
F = √(F₁² + F₂²)
F = √(15² + 22²)
F = 26.63 N
The direction of the force is the angle between the resultant force and the horizontal force.
tan θ = 15 / 22
tan θ = 0.6818
θ = tan⁻¹ ( 0.6818)
θ = 34°
Therefore, the overall force pushing on the block is 26.63 N in the direction of N 34° E

A car with a mass of 1,200 kg travels a distance of 150 m as it moves from
one stoplight to the next. At its fastest, the car travels at 22 m/s. What is its
kinetic energy at this point?
A. 290,400
B. 8,872 J
C. 580,800 J
D. 13,200 J
Answer:
A. 290,400
Explanation:
The kinetic energy of a car is 290,400J.
How to find Kinetic energy?Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2.
ke = 1/2mv^2
By using the formula, we get
= 1/2 * 1200 * 22^2
= 600 * 484
= 290,400 J
Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

In a study, the data you collect is Habits on a Always/Sometimes/Never scale.What is the level of measurement?
Answer:
Ordinal
Explanation:
There are four levels of measurement which include the nominal, ordinal, interval, and ratio. The data collected above is ordinal data as it qualifies the data and still indicates the ordering of the data. It gives the observer an idea of the range of data collected or its rating although mathematical calculations may not be done with it.
The other forms of data include the nominal which simply qualifies the data, the interval which qualifies the data but which the differences between the data can be obtained, and of course the data has no starting point. The ratio scale which is similar to the interval scale but which the ratios between the data obtained can be compared.

distance travelled by a train is 495 km in 4 hours 30 minutes, what is its speed in m/s?
Answer:
9.09m/s
Explanation:
Speed = Distance/Time
Distance = 495km
Time = 4 hr 30 min = 4 hr 1/2hr = 4.5 hr
Therefore, Speed = 495/4.5 = 110km/h
Now to convert km/h to m/s
110 x 1000/ 110 x 110
110 cancels out each other, we are now left with
1000/110 = 9.09m/s

Jan ran 4 miles north in 28 minutes. What was Jan's average velocity?
Answer:
3.83 m/s
Explanation:
Given that,
Distance covered by Jan, d = 4 miles
1 mile = 1609.34 m
4 miles = 6437.38 m
Time, t = 28 minutes = 1680 s
Jan's average speed,
v = d/t
[tex]v=\dfrac{6437.38\ \text{m}}{1680\ \text{s}}\\\\v=3.83\ \text{m/s}[/tex]
Hence, the average velocity of Jan is 3.83 m/s.

Think and discuss: Why do you think the rate of temperature change does not stay constant over time? If possible, discuss your answer with your teacher and classmates.
Because the temperature of the place its contained in is constantly changing, for example, if you put a room temperature item in the fridge it will become cold, or whatever the temperature you set your fridge to.
Variation in the factors of climate leads to variable temperature around the world.
The rate of temperature change does not stay constant over time because of changes occur in the climatic factors. The climatic factors such as latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds can't remain constant which leads to variable temperature in different regions of the world.
The temperature will remain the same if all the world has same environmental conditions so we can conclude that variation in the factors of climate leads to variable temperature around the world.
