The valence shell ( outermost shell ) electronic configuration of is ns2np3 , which clearly shows that all the elements have the tendency to make same kind if bonds with a common element.
That is, consider the hydrates of the group, it is NH3 ( ammonia ),PH3 (phosphine ), AsH3 (arsine ) , SbH3 ( stibine ) etc. They are having the same chemical formula and same type of bond (covalent bond )
The physical properties include melting point, boiling point, density etc.

Calculate the horizontal force that must be applied to a 1,300 kg vehicle to give it an acceleration of 2.6 m/s² on a level road.
500 N
3,380 N
1,302.6 N
0.002 N
Answers
The horizontal force must be applied to a vehicle of mass 1300 kg and of acceleration of 2.6 m/s² will be 3380 N. Hence, option B is correct.
What is Acceleration?The rate of change in an object's velocity concerning time is known as acceleration in mechanics. The vector quantity of accelerations. The direction of the net force that is acting on an object determines its acceleration.
Since acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is a vector quantity as well.
According to the question, the given values are :
Mass, m = 1300 kg
Acceleration, a = 2.6 m/s²
Force = 1300 × 2.6 m/s²
F = 3380 N.
So, the force applied will be, 3380 N.

Explanation:
The density has a formula of d = m / V.
The volumes are given as the same.
The density will be
d_lead = 113/ V
d_aluminum = 27/V
It does not matter for this question what the volume actually is. Just note that the value of the volume is the same for each ball.
A: incorrect. If the volumes are the same, the density is not the same because the masses are different.
B: incorrect. If the density of the two balls was less than water, the two balls would float. Never going to happen unless the balls are thin shells.
C: incorrect. The exact opposite is the answer.
D: Correct. This is the answer.

7. An object with a weight of 19.6 N moves with a constant velocity of 20.0 m/s. A net
force of 6.00 N is applied to the object in the direction of its motion for 4.00 seconds.
What is the final momentum of the object?
Answers
Answer:
118.4kgm/s
Explanation:
Given parameters:
Weight of object = 19.6N
mass of object = 19.6/9.8 = 2kg
Constant velocity = 20m/s
Force applied = 6N
Time taken = 4s
Unknown:
Final momentum of the object = ?
Solution:
To solve this problem, we use Newton's second law of motion;
Ft = m (v - u)
F is the force applied
t is the time taken
m is the mass
v is the initial velocity
u is the time taken
Ft = mv - mu
mv is the final momentum;
So;
Final momentum = Ft + mu
Final momentum = (19.6 x 4) + (2 x 20) = 118.4kgm/s

A 2 cm object is 10 cm from a convex lens that has a focal length of 4.4 cm. The image is 8 cm from the lens.
The height of the image, to the tenths place, is
cm.
Answers
Answer:
-1.6
Explanation:
e2021
The Height of an Image for a Convex Mirror is calculated by using magnification equation
m = h(i) / h(o) = − d(i) / d(o) ,where
the magnification index of the mirror, m
the height of the object, h(o)
the height of the image, h(i)
the distance between the object and the mirror, d(o)
the distance between the image and the mirror, d(i)
h(i)/ 2 = -8 / 10
h(i) = -1.6 cm.
What is convex mirror ?"Convex Mirror is a curved mirror where the reflective surface bulges out towards the light source. This bulging out surface reflect light outwards and are not used to focus light."
What is magnification equation ?"The formula for magnification is m=h(i)/h(o)=-d(i)/d(o). m is the total magnification; h(i) is the height of the image; h(o) is the height of an object; d(i) is the distance from the lens to the in focus projected image; d(o) is the distance of the object to the lens. The negative sign represents that the image is inverted."

A molecule contains 16 atoms and undergoes a chemical change. How does the
chemical change affect the total number of atoms of each element? (2 points)
Answers
Answer:
They remain the same
Explanation:
As the molecule goes from reactants to products, the number of atoms in the each of the element remains the same.
This is in compliance with law of conservation of matter. The law proposes that "in a chemical reaction, matter is neither created nor destroyed by changed from one form to another".
So, since no matter is destroyed, the number of atoms during a chemical change remains the same before and after a reaction.
This is applicable to all chemical changes.

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The battery is storing the energy but give it something to power and it'll give its energy to the object and a violin strings are like ruber band and if you play the violin it releases a new type of energy sound energy.
