Answer:
Since it is mentioned that the block is in equilibrium, this means the resultant force is zero, and all the forces cancel out each other.
You have to think it in a way so that, the forward force cancel out the backward force. Check the picture attached, on the forward side,
3N + 5N = 8N which cancel out the backward force of 8N

Planets A and B have the same mass, but planet A is half the size of planet B.
Which statement correctly explains the weight you would experience on each
planet?
A. You would weigh the same on both planets because your mass
would be the same on both.
B. You would weigh less on planet A because the distance between
you and the planet's center of gravity would be smaller.
C. You would weigh more on planet A because the distance between
you and the planet's center of gravity would be smaller.
D. You would weigh the same on both planets because the masses
of the planets are the same.
Answer: C
Explanation: I just finished the test on A P E X :)
Planets A and B have the same mass, but planet A is half the size of planet B, hence you would weigh more on planet A because the distance between you and the planet's center of gravity would be smaller, so option C is correct.
What is mass?A fundamental characteristic of an object, its inertia is quantified by its mass, which is a basic indicator of the volume of substance inside the thing. Because mass is such a fundamental quantity and is difficult to define in terms of another, definitions of it frequently appear circular.
It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.
Therefore, You would weigh more on planet A because the distance between you and the planet's center of gravity would be smaller.

What is the frequency of a wave with a wavelength of 7.88 x 10^(-8) m?
Answer:
f = 23.64 Hz
Explanation:
From the wave equation, the relationship between frequency and wavelength is given by;
f = cλ
Where;
λ is wavelength
c is speed of light with a constant value of 3 × 10^(8) m/s
f is frequency
We are given wavelength of 7.88 x 10^(-8) m
Thus;
f = 7.88 x 10^(-8) × 3 × 10^(8)
f = 23.64 Hz

A squirrel travels from one tree top to another. the distance between tree tops is 30 m and takes the squirrel 8 s to travel. What is the speed of the squirrel?
Answer:
3.75
Explanation:
Because when we use the formula S=D/T to find speed it will end up being
S= 30/8 because 30m is the distance and 8 s is the time.

If you neglect air resistance, the horizontal component of a projectile A. Is always changing B. Remains constant throughout the flight C. Increases, goes to zero, then increases D. Depends on who threw it
Answer:
B. Remains constant throughout the flight
Explanation:
If we completely neglect air resistance then the projectile will not have any horizontal resistances to deal with, therefore the horizontal component will remain constant throughout the flight. This would continue to be the case until it meets some form of resistance. Which assuming that everything else is normal would be the case since the force of gravity will push the projectile down (vertical component) until it hits the ground which in that instance would act as an opposing force to the horizontal component as well.

A ball with an initial velocity of 2 m/s rolls for a period of 3 seconds. If the ball is uniformly accelerating at a rate of 3 m/s2, what will be the ball’s final velocity?
Answer: 11 m/s
vinitial=2 m/s
time=3 s
acceleration = 3 m/s^2
vfinal = ?
The key here is that it is a constant acceleration, so we can use the constant acceleration equations. The easiest one to use would be:
vfinal=vinitial + a*t
We need vfinal, so algebraically we are ready to put in numbers into the equation:
vfinal=vinitial + a*t = 2 m/s + (3 m/s^2)*(3 s ) = 11 m/s is the final velocity
The ball's final velocity is 11 m/s
From one of equations of kinematics for linear motion
We have that
v = u + at
Where v is the final velocity
u is the initial velocity
a is the acceleration
and t is the time
From the given information in the question
u = 2 m/s
t = 3 secs
a = 3 m/s²
Putting these parameters into the above formula
v = u + at
We get
v = 2 + (3×3)
v = 2 + 9
v = 11 m/s
Hence, the ball's final velocity is 11 m/s

Explanation:
When a 12 N horizontal force is applied to a box on a horizontal tabletop, the box remains at rest. The force of friction acting on the box is
1) 0N
2) Between 0N and 12N
3) Exactly 12 N
4) Greater than 12N
Answer:
12N
Explanation:
when a force is applied to a body but still stays at rest or moves at a constant speed , the frictional force is equal to the force applied
The force of friction acting on the box is greater than 12N
For an object to move, the applied force has to be larger than the maximum force of static friction. If the force applied is less than the maximum force of static friction, the object would remain at rest.
Therefore, if a 2 N horizontal force is applied to a box and the box remains at rest, this mean that the force applied is less than the force of friction acting on the box. Hence the force of friction acting on the box is greater than 12N

Why does time seem to flow only in one direction?
Answer:
Time seem to flow in only one direction because it's from entropy. In tiny physics, time is directionally neutral.
Explanation:
Answer:
objects that store memories heat up as the operate(computers and brains). heat(energy) generation increases entropy. entropy is a measure of disorder. entropy is an irreversible process, so the laws of thermodynamics(law 1. energy can't be created or destroyed law 2. the total entropy must increase) require that such objects can only run in one direction: from past to present

Explanation:
A block is placed on an inclined plane and remains stationary, as shown in the figure above. A student claims, “The block remains stationary because as gravity tries to pull the block down the ramp, the block exerts an equal and opposite force on itself up the ramp.” Is the student’s claim correct? Justify your answer.
Answer:
No, according to Newton's first law of motion, the block cannot exert a force on itself, and the body will remain at rest unless unbalanced forces act on it
However according to Newton's third and first laws of motion the action of gravity pulling the block down the plane is equal to the reaction force of friction, preventing the motion
Explanation:
According to Newton's third law, the action force of gravity on the block tending to drag the block down along the inclined plane is equal to the reaction force of the frictional force of the inclined plane due to the interactions between the surfaces of the block and the plane which tends to prevent the motion of the block when both the component of the gravitational force down the plane and the frictional force are equal.

An automobile of mass 1500 kg is moving at 15 m/s. What
average net forward force is required to accelerate the
automobile to 25 m/s over a distance of 100 m?
Please I beg you help me
Answer:
Explanation:
m = 1500 kg
u = 15 m/s
v = 25 m/s
s = 100 m
[tex]v^{2} = u^{2} + 2as[/tex]
[tex]25^{2} = 15^{2} + 2a[/tex] × 100
625 = 225 + 200 a
-200a = 225 - 625
-200a = -400
a = 400 / 200
a = 2 m/s
f = ma
f = 1500 × 2
= 3000 N
