Answer:
The desk would move upwards.
Explanation:
A teacher places four books of different masses in a bookcase. The diagram shows the placement of the four books
The teacher states that the books are arranged in the bookcase for the lowest overall potential energy when only one book is on each shelf.
a. Use inequality symbols (<, >) to identify the relationship among the masses of all four books.
b. Describe how the arrangement of the books can be changed for the greatest overall potential energy when only one book is on each shelf.
a. P.E(Y)< P.E(W)< P.E(Z)< P.E(X)
mass m(Y)< m(W)<m(Z)<m(X)
b. The books arranged with book X in the bottom, book Z in 2nd position, book W in 3rd and book Y on the top.
What is gravitational potential energy?If an object is lifted, work is done against gravitational force. The object gains energy.
The equation for calculating gravitational potential energy is
GPE =mgh
where, GPE is the gravitational potential energy, m is the mass, h is the change in height and g is the acceleration due to gravity.
a) According to the heights of books, P.E(Y)< P.E(W)< P.E(Z)< P.E(X)
when arranged for lowest potential energy, book with the lowest mass will be placed in the lower position. Thus, relationship among masses, m(Y)< m(W)<m(Z)<m(X)
b) The arrangement of the books can be changed for the greatest overall potential energy when only one book is on each shelf. The books arranged with book X in the bottom, book Z in 2nd position, book W in 3rd and book Y on the top.

i need help with this plsssss
Answer:
Increased ; Decreased
Explanation:
Force = Mass x Acceleration
If I increase my mass (by putting in books in the box) shouln't my acceleration go down since they are inversely related to each other (when one goes up, the other goes down and vice versa). My force stayed the same at 10 N, thus only mass and acceleration fluctuated relative to each other.

Answer:
A) Inertia
Explanation:
Inertia is why objects tend to resist changes in their motion. Like a rolling ball will keep rolling unless we try to add friction to it, which then would stop the ball.
Answer:
Option A
Inertia = the resistance an object has to a change in its state of motion.
If the mass of a duffel bag is less than the mass of a suitcase, what is true if both are slid across an airport floor?(1 point)
Both objects would be able to move at the same time.
The duffel bag will contain more matter than the suitcase.

What is observed as the distance between the rest position and the crest of a light wave decreases?
A. The light becomes more violet
B. The light becomes dimmer
C. The light becomes brighter
D. The light becomes more red
Answer: answers B
Explanation: it gets dimmer becuase less light......
As it is observed the distance between the rest position and the crest of a light wave decreases, and the light becomes dimmer, therefore the correct answer is option B.
What is Wavelength?It can be understood in terms of the distance between any two similar successive points across any wave for example wavelength can be calculated by measuring the distance between any two successive crests.
C = λν
As given in the , it is observed the distance between the rest position and the crest of a light wave decreases,
The right response is option B since it can be seen that when the distance between the rest position and the crest of a light wave decreases, the light becomes dimmer.

You find the answer by solving the problem.
You can solve the problem by using the equation that tells how force, mass, and acceleration are connected.
The equation is in the "Hint".
F = m • a
Force = mass • acceleration
mass = 200 kg
acceleration = 2 m/s^2
Force = (2000 kg) • (2 m/s^2)
Force = 400 Newtons
