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.

Which material will heat up the most quickly if placed near a heat source?
Rubber
Plastic
Glass
Metal
Answer:
Metal
Explanation:
Just answered on Apex
Metal is the material will heat up the most quickly if placed near a heat source. Option D is correct.
What is heat ?
The movement of energy from a hot to a cold item is characterized as heat. Heat energy flows from a hot material to a cold one.
This occurs because faster-vibrating molecules transmit their energy to slower-vibrating ones. Heat content is another name for vibrational energy.
It is hot or chilly depending on how much heat is there in the body. The body will be hotter as the heat content increases. The movement of energy from a hot to a cold item is characterized as heat.
The heat flow in the material is due to the free electrons. In the metal, no of free electron is highest. Metal is the material will heat up the most quickly if placed near a heat source.
Hence, option D is correct.

Explanation:Flexibility and stretching: preventing sports injuries
Many may know about all the different types of sports around the world. Lots can leave serious injuries. All across the world more than 1.2 million people have been injured because of sports or maybe more than that. Most of the injuries have been kids. To prevent these injuries from happening. One thing is stretching if you don’t stretch your bones more than likely you are not into your flexibility and reflexus that for they are very weak. If there is not enough flexibility within your movement you are more than likely not able to stretch. It can help the growth within your bone as well. If you have growth in your bones then you will get less injuries. If you break a bone such as your leg or sprain there is a chance that you will have problems with that specific leg later on in life. To prevent these types of events from happening I say stretch before a sporting game. Stretching can help with the impact of your flexibility. For example, Olympic gymnasts are able to do lots of tricks because their bones have flexibility in their bones. That's not saying that they will not hurt themselves, it's just such a low risk because their bone grew strength and flexibility. Some people's bones can be very sensitive then others so it might be kind of hard for them to be flexible. Another way to help people with their bone flexibility is drinking milk. Milk helps grow your bones. This can help prevent sport injuries in many ways. Lots of people get hurt in football to be more specific because it's such a durable sport as in tough. If they drink a lot of protein and milk before a game maybe even Carbohydrates their bones will be ready for the game. Flexibility and stretching can go lots of ways when it has to do with your body.

An airplane flies 33 m/s due east while experiencing a tailwind
of unknown velocity due north. The resultant velocity is
determined to be 35.11 m/s northeast. What is the velocity of
the northern tailwind?
Explanation:
Use Pythagorean theorem.
v² = vₓ² + vᵧ²
(35.11 m/s)² = (33 m/s)² + vᵧ²
vᵧ = 12 m/s
The velocity of the northern tailwind is 12 m/s.
To find the velocity of northern tailwind, the given values are,
Resultant velocity v = 35.11 m/s,
Velocity of plane vₓ = 33 m/s.
What is the resultant velocity?The resultant velocity of the plane is the sum of the velocities of the plane and the wind with the consideration of their directions. The sum of the vector forces on an object is equal to the scalar product of the object's mass and its acceleration vector.The plane heads east and the wind being a tailwind also heads north east. Hence, we add their values using Pythagorean theorem,Use Pythagorean theorem.
v² = vₓ² + vᵧ²
(35.11 m/s)² = (33 m/s)² + vᵧ²
vᵧ² = 35.11² - 33²
vᵧ² = 1232.71 - 1089
vᵧ = √143.71
vᵧ = 11.98 m/s
which can be vᵧ = 12 m/s
Hence, the velocity of the northern tailwind is vᵧ = 12 m/s.

A boy wants use his slingshot to shoot a water balloon into the air. His
slingshot has a spring constant of 60 N/m, and he pulls it back 1.5 m before
releasing the water balloon and launching it into the air. If air resistance can
be ignored and the water balloon has a mass of 0.5 kg, what is the
approximate maximum height that the water balloon can reach? (Recall that g
= 9.8 m/s2)
O A. 7.0 m
B. 4.6 m
C. 9.3 m
D. 13.8 m
Answer:
A. 70 m OS the correct one
The approximate maximum height that the water balloon can reach is 13.8 m, The correct option is D.
What is the conservation of energy?Conservation of energy is a fundamental principle in physics that states that energy cannot be created or destroyed, only transformed or transferred from one form to another. In other words, the total amount of energy in a closed system remains constant over time. This principle is based on the idea that energy is a fundamental property of the universe, and it is a key concept in many areas of science, including physics, chemistry, and engineering. The law of conservation of energy is used to analyze and understand a wide range of physical phenomena, from the behavior of subatomic particles to the workings of the entire universe.
Here in the Question,
The maximum height that the water balloon can reach can be found using conservation of energy. The initial potential energy stored in the slingshot is transformed into kinetic energy of the water balloon as it is launched into the air, and then into potential energy at the maximum height.
The initial potential energy of the slingshot is given by:
PE = (1/2)kx^2
where k is the spring constant (60 N/m) and x is the distance pulled back (1.5 m)
PE = (1/2)(60 N/m)(1.5 m)^2
PE = 67.5 J
At the maximum height, all of the initial potential energy is converted into potential energy due to gravity:
PE = mgh
where m is the mass of the water balloon (0.5 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the maximum height.
h = PE/(mg)
h = 67.5 J/(0.5 kg)(9.8 m/s^2)
h ≈ 13.8 m
Therefore, the approximate maximum height that the water balloon can reach is 13.8 m, which is option D.

Answer:
4 seconds
Explanation:
Given:
Δy = 0 m
v₀ = 20 m/s
a = -10 m/s²
Find: t
Δy = v₀ t + ½ at²
0 m = (20 m/s) t + ½ (-10 m/s²) t²
0 = 20t − 5t²
0 = 5t (4 − t)
t = 4

Which of these objects could be falling with constant acceleration?
Answer:
1 and 2
Explanation:
If an object has constant acceleration, it's displacement at time t is:
Δx = v₀ t + ½ at²
For object 1:
0.44 = (0) (0.3) + ½ a (0.3)²
a = 9.78
3.14 = (0) (0.8) + ½ a (0.8)²
a = 9.81
So object 1's acceleration is approximately constant.
For object 2:
0.06 = (0) (0.3) + ½ a (0.3)²
a = 1.33
3.09 = (0) (2.1) + ½ a (2.1)²
a = 1.40
So object 2's acceleration is approximately constant.
For object 3:
0.44 = (0) (0.3) + ½ a (0.3)²
a = 9.78
3.09 = (0) (2.1) + ½ a (2.1)²
a = 1.40
So object 3's acceleration is not constant.

Two point charges +3 micro coulomb and +8 micro coulomb repel each other with a force of 40N . If a charge of -5 micro coulomb is added to each of them, then the force between them will become?
Answer:
1 N
Explanation:
Given that two point charges +3 micro coulomb and +8 micro coulomb repel each other with a force of 40N.
Let us first calculate the distance between the two point charges
F = (KQq)/r^2
Where K = 9.0 × 10^9Nm^2C^-2
40 = (9×10^9 × 3×10^-6 × 8×10^-6)/r^2
Make r^2 the subject of formula
r^2 = 0.216/40
r = sqrt (5.4^-3)
r = 0.0735 metres
If a charge of -5 micro coulomb is added to each of them, then the force between them will become?
Using the same formula again
F = ( KQq)/r^2
Where Q = 8 - 5 = +3 × 10^-6 C
q = 3 - 5 = - 2 × 10^-6 C
F = ( 9×10^9 × 3×10^-6 × 2×10^-6 )/5.4×10^-2
F = 0.054/0.054
F = 1 N
The force of attraction between the two point charges will be 1 N
