Answer:
option will be ''B'' 0N
Explanation:
There are two forces acting upward 8N and 14N which is equal to 22N(upward force)
since, 22N is also acting downwards
both the forces will cancel each other and the the outcome will be zero.
Now, there is a 3N force acting on the left and right. So, they too, will cancel each other and the result will be zero.

Why don't you feel the pressure exerted by the atmosphere?
Answers
Answer:
the air within our bodies (in our lungs and stomachs, for example) is exerting the same pressure outwards so there's no pressure difference and no need for us to exert any effort.
Explanation:
Because in our body blood also exerts pressure that's why we don't feel atmospheric pressure.

a toy airplane is flying at a speed of 8 m/s with an acceleration of 0.9 m/s^2. How fast is it flying after 2 seconds? A)9.8 m/s B)8.1 m/s C)5.2 m/s D)3.6 m/s
Answers
Answer:
A) 9.8m/s this answer is correct.
The acceleration is increasing by 0.9m/s^2 .
so, in each second it will increase by 0.9m/s^2.
Therefore, in 2 second
0.9 * 2
= 1.8m/s
Now,
8 + 1.8
= 9.8m/s

If each washer has a mass of 4.9 g, then the mass of two washers in kilograms would be Given that F = ma, and if 4 washers are attached to the string and car instead of 2, then the applied force on the car will be
Answers
Given that,
Mass of each washer = 4.9 g
We need to calculate the mass of two washers in kg
Using conversion of unit
Mass of each washer [tex]m= 4.9\times10^{-3}\ Kg[/tex]
So, Mass of two washers is
[tex]M=2\times m[/tex]
Put the value of m
[tex]M=2\times4.9\times10^{-3}\ k[/tex]
[tex]M=0.0098\ Kg[/tex]
If 4 washer are attached to the spring
We need to calculate the applied force on the car
Using formula of force
[tex]F=mg[/tex]
Put the value into the formula
[tex]F=4\times4.9\times10^{-3}\times9.8[/tex]
[tex]F=0.192\ N[/tex]
Hence, (i), The mass of two washers is 0.0098 kg.
(ii). The applied force on the car is 0.192 N.

What is the negative outcome of consolidation from many slaughterhouses across the US to only 13? A less greenhouse gas emissions B greater profits for agricultural corporations C less cost for farmers D greater possibility of contamination of our food
Answers
Answer:
D greater possibility of contamination of our food
Explanation:
Slaughterhouses are the places where animals are slaughter to supply food and when these places are consolidated, the few ones that remain receive a higher amount of animals and the meat from those animals can be combined in a batch which increases the chance of it to get contaminated. According to that, the answer is that the negative outcome of consolidation from many slaughterhouses across the US to only 13 is greater possibility of contamination of our food.
The other options are not right because they would be considered positive outcomes.

Why do atoms bond? Describe examples of the two ways elements complete their valence
shell through bonding
Answers
Answer: kindly see Explanation
Explanation:
Atoms bond in other to achieve a stable valence electron shell. Through bonding, atoms with incomplete valency in the outer shell may accept, lose or share electrons with another atom in other to achieve a stable outer shell or configuration.
Ionic bonding:
Ionic or electrovalent bonding simply occurs when atoms accept or lose electrons in their outer shell in other to achieve stability. Elements that require 1 atom to achieve stability accepts from elements which requires losing 1 atom in other to achieve a stable outer shell.
Example is Sodium chloride (NaCl) sodium loses one atom, which chlorine accepts and both achieve a stable outer shell.
Covalent bonding simply refers to electron sharing between atoms. Instead of losing or accepting, the atoms bond by sharing electron to achieve stability. Such is the bonding between Hydrogen and Oxygen in the formation of H2O, oxygen requires two electrons to attain stability, each hydrogen atom requires one each to attain stability, through sharing oxygen attains two more electrons, one each from the hygrogen atoms and the oxygen atom also shares one electron with each hydrogen atom. Then all the atoms atoms stability.
Answer:
1.) Atoms bond in order to gain more stability.
2.) They can complete their valence by sharing (taking and giving) electrons for 1.)

What would happen to a satellite if its orbit speed was reduced by half?
PLEASE ANSWER QUICKLY
Answers
Answer:
The radius of orbit will increase by 4, the satellite will move away from the Earth
Explanation:
The orbital speed of any body revolving in an orbit around another boyd is given by:
v (orbital) = √(G · M(central body)/R)
Where G is the gravitation constant.
If the body, e.g satellite is moving around the Earth, then the mass of central body M will also be a constant. Therefore, the only thing on which the orbital velocity will depend on will be Radius of the orbit R.
v ∝ 1/√R
√R ∝ 1/v
Take square:
R ∝ 1/v²
If the velocity of satellite is reduce to half, then:
R' ∝ 1/ (v/2)²
R' ∝ 1/(v²/4)
R' ∝ (4)(1/v²)
R' ∝ (4)(R)
The radius of orbit will increase by 4, the satellite will move away from the Earth

What would happen to a satellite if its orbit speed doubled?
Answers
Answer:
The radius of orbit will decrease by 1/4, the satellite will come closer to Earth
Explanation:
The orbital speed of any body revolving in an orbit around another boyd is given by:
v (orbital) = √(G · M(central body)/R)
Where G is the gravitation constant.
If the body, e.g satellite is moving around the Earth, then the mass of central body M will also be a constant. Therefore, the only thing on which the orbital velocity will depend on will be Radius of the orbit R.
v ∝ 1/√R
√R ∝ 1/v
Take square:
R ∝ 1/v²
If the velocity of satellite will doubles, then:
R' ∝ 1/ (2v)²
R' ∝ 1/4v²
R' ∝ (1/4)(1/v²)
R' ∝ (1/4)(R)
The radius of orbit will decrease by 1/4, the satellite will come closer to Earth

What is Newton's second law?
Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
The mathematical expression for Newton's second law is as follows
F = m*a
where F represents the force applied
m is the mass of the object
a is the acceleration of the object
The initial acceleration of an airplane with a total mass of 850 kg has an engine malfunction, causing it to provide a constant horizontal force of 4000 N.
F =m*a
4000 N = 850×a
a= 4.7 m/s²
An acceleration of airplane when the pilot, who has a mass of 80 kg, decides to eject from the airplane. With the reduced total mass,
the horizontal force is the same 4000 N, now the total reduced mass the airplane is 770 kg
F =m*a
4000 =770×a
a = 5.2 m/s²
