Which two factors affect the amount of thermal energy an object has?
O A. The amount of space between the particles of the object
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.

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.

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.

Although two identical objects may have the same mass and the same weight (meaning that the force of gravity is the same for both), they may not fall to Earth at the same rate. This is because of air resistance. Any object that is falling has friction, or resistance, from the air. The larger the object, the more resistance it has as it falls.
Get two identical pieces of paper. Crumple one up into a ball, but leave the other one a flat sheet. Drop both pieces of paper off a high place at the same time. What happens? Which falls faster? Record your observations and make a conclusion, using the terms “mass,” “weight,” “force,” “resistance,” and “gravity.”
MUST BE AT LEAST 4 sentences and include the terms weight, force, resistance, and gravity.
Answers
Answer:
the paper ball falls faster and the unfolded paper falls at a slower rate
Explanation:
this is because gravity is pulling both objects down to the ground and hence they are falling. Both objects have the same mass and weight but the resultant force of the paper ball is smaller than that of the unfolded paper. The unfolded paper has a larger surface area and so a larger force is acted upon it, meaning there is more air resistance. This shows that the paper ball falls faster than the unfolded paper.
The air resistance acting on the crumpled ball will be less and hence it will fall faster.
What is Air resistance?
Air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. The larger the object, the more resistance it has as it falls.
Mathematically, we can write it as -
F = [tex]\frac{1}{2} C_{D}[/tex] × ρv²A
Given are two identical pieces of paper such that one is crumpled up into a ball and the other one is left as flat sheet.
Now, as you throw both, the crumpled up ball and the flat sheet, the crumpled up ball will fall faster. The main reason behind this is that the total surface area of the crumpled ball in contact with the air is less than compared to that of the flat sheet. Air resistance on the crumpled ball with surface are in contact [say A(c)] can be written as -
F[1] = [tex]\frac{1}{2} C_{D}[/tex] × ρv²A(c)
And that on the flat sheet with area of contact with the air [say A(f)] can be written as -
F[2] = [tex]\frac{1}{2} C_{D}[/tex] × ρv²A(f)
Now as A(f) > A(c), therefore F[2] > F[1]
Therefore, the air resistance acting on the crumpled ball will be less and hence it will fall faster.
