What do x-direction and y-direction refer to when discussing an object's motion
Answer:
The x-direction and y-direction refer are used to refer to the location of an object as well as to the components of the motion of the object in a two dimensional space
Explanation:
In physics, in the analysis of the motion of an object in two dimensional space, the relative location of the object is specified using the measured distances in the x-direction from the y-axes and y-direction from the x-axes
In order to accurately specify the motion of the object, information regarding the component of the motion of the object in the x-direction and the component in the y-direction are required

Which has more momentum? A 60 kg object traveling at 3 m/s or a 9 kg object traveling at 23 m/s.
Answer:
If we compare 270 J and 2 380.5 J the higher is 2 380.5 J which is A 9 kg object traveling at 23 m/s
Explanation:
A 60 kg object traveling at 3 m/s
Given:
m = 60 kg
v = 3 m/s
Unknown:
KE or kinetic energy
Formula and solution:
KE = 1/2 mv²
KE = 1/2 (60kg) (3m/s)²
KE = (30kg) (9m²/s²)
Final Answer:
KE = 270 kg·m²/s² or simplify as 270 J
A 9 kg object traveling at 23 m/s
Given:
m = 9kg
v = 23m/s
Unknown:
KE or kinetic energy
Formula and solution:
KE = 1/2 mv²
KE = 1/2 (9kg) (23m/s)²
KE = (4.5kg) (529m²/s²)
Final Answer:
KE = 2 380.5 kg·m²/s² or simplify as 2 380.5 J

A person throws a ball horizontally from the top of a building that is 26.1 m above the ground level The ball lands 112 m away from the base of the building Neglect air resistance and useg = 9.81 m/s ^ 2
Answer:
v = 5.21 m/s
Explanation:
Let the initial speed be v.
The top of a building is 26.1 m above the ground level and the ball lands 112 m away from the base of the building.
We need to find the initial velocity of the ball.
Let it was at rest initially. Using the second equation of motion to find time of flight.
[tex]d=ut+\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2d}{g}} \\\\t=\sqrt{\dfrac{2\times 26.1}{9.81}} \\\\t=2.3\ s[/tex]
No, using the formula of speed.
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{12\ m}{2.3\ s}\\\\v=5.21\ m/s[/tex]
So, the initial velocity of the ball is 5.21 m/s.

Why is thermal energy classified as kinetic energy?
Answer:
Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat.

Explanation:
When a ball is sitting still on top of a table, are the forces acting upon it balanced or unbalanced?
Answer:
Balanced
Explanation:
If a stationary object is staying still (in this case it's the ball) all of the forces acting upon it are balanced. If an object moving has balanced forces, it would move in the same direction at the same speed until a different outside force interrupts the equilibrium.
Hope this helps :)
This question involves the concepts of Newton's Second Law and Balanced Force.
The forces acting upon the ball are "Balanced".
Newton's Second LawAccording to Newton's Second Law whenever an unbalanced force is applied on an object, it produces an acceleration in the object in the direction of the force itself. This acceleration is directly proportional to the magnitude of the force and inversely proportional to the mass of the object.
Since, the ball is at rest and not moving. Hence, it has no acceleration and no unbalanced force is applied on it. The weight of the ball is balanced by the normal reaction provided by the table. Therefore, the forces acting on the ball are Balanced Forces.

Why are ions formed?
Group of answer choices
A.Because atoms have the same number of protons and electrons
B. Because atoms want 8 valence electrons
C. To make our lives difficult
D. Because atoms gained neutrons
Answer:
B. Because atoms want 8 valence electrons
Explanation:
Ions are formed because atoms want 8 valence electrons. Most atoms attain stability when they 8 electrons in their outermost shell.
This is the reason why they form ions.
To form ions, atoms will gain or lose electrons or share them. This loss, gain, or sharing of electrons often lead to an atom become stable. One group of atoms, the noble gases, do not form ions readilyThey have complete numbers of electrons in their valence shells. So they do not gain, lose or share their electrons to form ions unlike the others.when maggie applies the brake of her car, the car slows
5. A book is placed on a table. If the book exerts a force of 15 N'on the table,
how much force does the table exert on the book?
A. ON
C. 9.8 N
B. 3 N
D. 15 N
Answer:
D
Explanation:
The table is NOT in motion, so it will remain still. Newton's second law states that for every action, there's an equal and opposite reaction. Therefore, the table must push back the opposite direction(up) with the same force(15N)

1.8 m/s²
2170 m/s²
343 m/s²
0 m/s²
Answer:
The answer is 1.8 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
where
m is the mass
f is the force
From the question we have

One frequent sign of gender inequality in the United States is that women do not ___________. A. enjoy the same voting rights as men B. earn as much as men in similar occupations C. receive admission to college as much as men D. have equal power in most relationships
One frequent sign of gender inequality in the United States is that women do not earn as much as men in similar occupation. So, option (B) is correct.
What is gender inequality?Men and women are not treated equally in society, which social problem is referred to as gender inequality. Distinctions in genetics, psychology, or prevailing cultural norms in the society may be the cause of the treatment. While some of these distinctions are based on scientific research, others seem to be social constructs.
Numerous areas of study, such as education, life expectancy, personality, interests, family life, careers, and political affiliation, demonstrate the differences in gender experiences. Gender inequality impacts non-binary people and is experienced differently across cultural boundaries.
In the United States, One frequent sign of gender inequality is that women do not earn as much as men in similar occupations. So, option (B) is correct.
