The gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object
The gravitational potential energy of a falling apple is maximum when the apple is at maximum height. As the apple begins fall to the ground the potential energy decreases and it will be transformed to kinetic energy.
[tex]P.E_i + K.E_i = P.E_f + K.E_f[/tex]
The potential difference in a battery is total energy stored in the battery.
Thus, the gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object.

The similarity is that both the battery and the falling apple have stored energy.
We define the potential energy of an object as stored energy in that object.
A battery has potential energy, it is stored until you connect it to something and allow that energy to flow.
Similarly, when the apple is in the air it has potential energy, that will be transformed into kinetic energy as it falls (as the apple falls, its velocity increases, thus, the kinetic energy increases).
So both, the apple and the battery have stored energy, and that is the similarity between these two.

Answer:
22.9km
Explanation:
If the mountain is 1.00 km higher in elevation than your position and the angle measured from your position to the top of a mountain is 2.50∘.then you would have been 22.9 km far away from the mountain
What are trigonometric functions?A right-angled triangle's side ratios are the easiest way to express a function of an arc or angle, such as the sine, cosine, tangent, cotangent, secant, or cosecant. These functions are known as trigonometric functions.
As given in the problem you measure the angle from your position to the top of a mountain to be 2.50∘. If the mountain is 1.00 km higher in elevation than your position,
By using the tangent trigonometric function for the right triangle
tanθ = height /distance
tan 2.5° = 1000 m /distance
distance =1000 m /tan 2.5°
=22903 m
=22.9 km
Thus, the mountain is 22.9 km far away from your position

How did Lavoisier's study of combustion prove that fire was not an element?
Answer:
In June 1783, Lavoisier reacted oxygen with inflammable air, obtaining "water in a very pure state." He correctly concluded that water was not an element.
Explanation:
As the fire left behind ashes of a substance it indicated that it is not an element as element cannot be decomposed in to simpler substances.
What is an element?It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

It's Friday night and Skyler has been assigned the noble task of baby-sitting Casey, his 2-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As Skyler starts across the street, he exerts a 52 N forward force on the wagon. There is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N. Construct a free body diagram depicting the types of forces acting upon the wagon. Then determine the net force, mass and acceleration of the wagon.
Answer: It's Friday night and Skyler has been assigned the noble task of baby-sitting Casey, his 2-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As Skyler starts across the street, he exerts a 52 N forward force on the wagon. There is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N. Construct a free body diagram depicting the types of forces acting upon the wagon. Then determine the net force, mass and acceleration of the wagon.
Explanation:
When Skyler exerts a force of 52 N on the wagon and there is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N then Net force, mass and acceleration of the wagon will be 305.2 N, 31.02kg and 0.9 m/s² resp.
What is Force ?Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. when net force acting on body is zero then it is called as balanced force and net force on the body is non zero then it is called as unbalanced force. unbalanced force are responsible for the motion of the body.
in this problem, Skyler is applying 52 N force to a wagon, there is resistance of 24N of force. Combined Wight is 304 N is directed downwards. a vector diagram is shown in the figure which gives the Net force.
the resultant force between resistance and applied force
F = 52 - 24 = 28N... means total of 28N of actual force is applied on the wagon in x direction.
There is downward force as weight, hence magnitude of net force acting on the wagon is.
F²(net) = F₁²+F₂² + F₁F₂cosθ
θ = 90, cos 90 = 0
F²(net) = F₁²+F₂²
F²(net) = 28² + 304²
F²(net) = 93200
F (Net) = [tex]\sqrt{93200\\[/tex] = 305.2 N
To get mass and acceleration,
weight W = mg
304 = m*9.8
m = 31.02 kg mass of the wagon is 31.02kg
F = ma
28 = 31.02*a
a = 0.9 m/s²
Acceleration of the wagon is 0.9 m/s². this is forward acceleration.
Hence Net force, mass and acceleration of the wagon is 305.2 N, 31.02kg and 0.9 m/s² resp.

what makes a force a vector quantity
Answer:
A vector quantity is a quantity that has both magnitude and direction.
Explanation:
What can we say when one force
is greater than another force?
A. There is no net force.
B. There is no change in motion.
C. There is a change in motion.
D. The forces are in equilibrium.
When one force is greater than another force, we can say that there is a change in motion. The correct answer is option C: "There is a change in motion."
According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. When one force is greater than another force, the net force acting on the object is not zero. If the net force acting on an object is not zero, it will cause the object to accelerate in the direction of the larger force. This acceleration leads to a change in motion. The object may speed up, slow down, change direction, or a combination of these.
Option A, "There is no net force," is incorrect because if one force is greater than another, there is a net force acting on the object.
Option B, "There is no change in motion," is incorrect because, as explained above, a greater force leads to a change in motion.
Option D, "The forces are in equilibrium," is incorrect because if one force is greater than another, the forces are not balanced, and the object is not in equilibrium.
Therefore, the correct statement is that there is a change in motion when one force is greater than another force.
