Answers
Answer:
Given
mᴀ = mʙ = mᴄ = 62 kg
Fᴀ = 480N
Fʙ = 240 N
Fᴄ = 600 N
Asked
aᴀ, aʙ, aᴄ = ?
Solution
Based on the question, we know that the mass of road A, road B and road C are same. And, the formula of acceleration is
so, we can calculate the acceleration of road A, road B and road C.
• for road A
aᴀ = 7,7419 m/s²
aᴀ = 7,75 m/s²
• for road B
aʙ = 3,8709 m/s²
aʙ = 3,87 m/s²
• for road C
aᴄ = 9,6774 m/s²
aᴄ = 9,68 m/s²

2. What happens if a new organism is added to an ecosystem or if the temperature was to change suddenly?
A. First of all, we would have to know if the new animal is king of the wild or a victim for the king. If its king, we would start to see the population decrease of certain animals and increase of that specie. If its not king we would see an increase in the population of the kings of the wild and decrease in the new specie.
B. If the temperature changed all of a sudden we would see many species die out due to them not being able to adapt to that certain atmosphere.

If a steel nail is wrapped 8 times with an insulated copper wire and each end of is attached to a 1.5 V battery, we find that it will lift the weight of 2 large paper clips. We hypothesized that for each 8 coils, you will be able to pick up one additional paper clip. When we ran the experiment, we observed and recorded that when we added 8 more wraps around the nail (16 coils) we could lift 4 paper clips and when we added 8 more wraps (24 coils) we could lift 6 paper clips. Choose the correct conclusion to the experiment.
1. We redesign the test and hope for better results.
2. We concluded that every time we add 8 wraps to the nail the total number of paper clips lifted doubled.
3. We concluded that our original test flawed. Because of the results, 8 coils should be able to pick up 2 paper clips. We will check our original test with a fresh battery.
4. We concluded that something went wrong with the experiment since it didn't give us the results we expected.

B. The average kinetic energy of the particles of the object
O C. The mass of the object
O D. The directions in which the particles of the object are moving
Answers
Answer:
B and C
Explanation:
just did the quiz
The factors that influence amount of thermal energy that is found in an object are:
B: The average kinetic energy of the particles of the object
C:The mass of the object
Thermal energy can be regarded as the kinetic energy which is energy that is involved in the random motions of the molecules of object.It can be referred to as heat energy and it's been measured in joules or calories,One of the factors that affect the amount of this energy in an object is average kinetic energy of the particles that are present in that object, if the amount of the kinetic energy is high, then the object will have high thermal energy This is because the particle are in motion and not fixed.
Therefore option B, C are right.

Answers
Answer:
There are two forces acting in opposition to the driving force, so the friction and the road and the air resistance. The air resistance is much greater than the friction with the road when a vehicle is in motion. When a vehicle is at rest, all of the forces acting on it are balanced.
Which of the following is an example of an unbalanced force?
(A) A ball on the grass
(B) A book sitting on a table
(C) A chair leaning on the wall
(D) A stroller being pushed
Answers
Answer:
d
Explanation:
because the motion is changing as it slows down mark brainliest to help me out :)
The example of an unbalanced force is a stroller being pushed. The correct option is D.
What is unbalanced force?An object is said to be acted upon by an unbalanced force only when an individual force is not balanced by a force of equal magnitude and direction.
Unbalanced forces are caused by a forward force or thrust and a frictional force opposing each other.
Friction is an opposing force to motion. It occurs whenever two surfaces rub against each other, such as when you rub your hands together or apply the brakes on a bike or car.
Forces that are balanced are those that are opposite in direction and equal in size.
Equilibrium is defined as the presence of balanced forces. There is no change in direction when forces are balanced.
As here pushing a stroller is not balancing the force as the force applied is more than the opposing one.
Thus, the correct option is D.

What are Chemical reactions?A chemical reaction is a process in which one or more substances are converted into different substances. The chemical reaction involves reactants and products.
A chemical reaction rearranges the constituent of atoms in reactions to produce different products. The reaction involves the change in the position of electrons and also involves the breaking of chemical bonds to produce products.
The substance involves in the reaction initially is called reactant. The reactions are chemically changed from the reactant to form products. The reactant is converted into products dependent on the reaction rate.
The reactions must be balanced to form a reactant and product. The number of atoms present in the reactants must be equal to the number of atoms present in the products.
From the given reaction,
4Al + 3O₂ ---- > 2Al₂O₃
