Answer: the answer is B. Extremely slow movement is not easily observed directly.
Extremely slow movement is not easily observed directly.
What are Continents?One of Earth's seven major landform divisions is the continent. The continents are Asia, Africa, North America, South America, Antarctica, Europe, and Australia, in order of largest to smallest.
Geographers typically include all the islands connected to a continent when identifying it. For instance, Japan is a country that belongs to Asia. Normally, all of the Caribbean Sea islands and Greenland are regarded as being in North America.
The combined area of the continents is roughly 148 million square kilometers (57 million square miles). Most of Earth's land surface, but not all of it, is made up of continents. Islands that are not physically a part of continents make up a minuscule amount of the overall land area.
Therefore, Extremely slow movement is not easily observed directly.

differentiate among the various forms of energy
Explanation:
Forms of energy
There are many different types of energy, which all fall into two primary forms – kinetic and potential. Energy can transform from one type to another, but it can never be destroyed or created.
Burning Questions
What are the different types of energy?
Types of energy can be categorised into two broad categories – kinetic energy (the energy of moving objects) and potential energy (energy that is stored). These are the two basic forms of energy. The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
Discover the different types of energy
Thermal Energy
Thermal (Heat) Energy
Thermal energy is created from the vibration of atoms and molecules within substances. The faster they move, the more energy they possess and the hotter they become. Thermal energy is also called heat energy.
Let's go! >
Chemical Energy
Chemical Energy
Chemical energy is stored in the bonds of atoms and molecules – it is the energy that holds these particles together. Stored chemical energy is found in food, biomass, petroleum, and natural gas.
Let's go! >
Nuclear Energy
Nuclear Energy
Nuclear energy is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission). Nuclear power plants split the nuclei of uranium atoms to produce electricity.
Let's go! >
Electrical Energy
Electrical Energy
Electrical energy is the movement of electrons (the tiny particles that makeup atoms, along with protons and neutrons). Electrons that move through a wire are called electricity. Lightning is another example of electrical energy.

Radiant Energy
Radiant Energy
Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Examples include the energy from the sun, x-rays, and radio waves.

light Energy
Light Energy
Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.
Let's go! >
Motion Energy
Motion Energy
Motion energy – or mechanical energy – is the energy stored in objects; as objects move faster, more energy is stored. Examples of motion energy include wind, a flowing river, a moving car, or a person running.
Let's go! >
Sound Energy
Sound Energy
Sound energy is the movement of energy through substances. It moves in waves and is produced when a force makes an object or substance vibrate. There is usually much less energy in sound than in other forms of energy.
Let's go! >
Elastic Energy
Elastic Energy
Elastic energy is a form of potential energy that is stored in an elastic object - such as a coiled spring or a stretched elastic band. Elastic objects store elastic energy when a force causes them to be stretched or squashed.

Gravitational Energy
Gravitational Energy
Gravitational energy is a form of potential energy. It is an energy associated with gravity or gravitational force – in other words, the energy held by an object when it is in a high position compared to a lower position.

What is the Law of Conservation of Energy?
While it might sound complex, the First Law of Conservation of energy simply states that energy can never be created or destroyed, but it can be transformed from one type to another.
What Do You Mean?
Types of Energy Diagram
Energy can be transformed from one form to another in different ways.
Kinetic energy is the energy of a moving object.
Potential energy is energy that is stored in an object or substance.
The Law of Conservation of energy is that energy can be transformed from one form to another, but can be neither created or destroyed.

Explanation:
a ball is rolling ar 4.80m/s over level ground when it encounters a ramp which gives it an acceleration of -0.875m/s^{2. if the ramp is 0.750m long, what is the final velocity of the ball when it reaches the top of the ramp?
Answer:
4.66m/s
Explanation:
Given parameters:
Initial velocity = 4.8m/s
Acceleration = -0875m/s²
Length of the ramp = 0.75m
Unknown:
Final velocity = ?
Solution:
To solve this problem, we apply the right motion equation;
V² = U² + 2aS
V is the final velocity
U is the initial velocity
a is the acceleration
S is the distance = length of ramp
Insert the parameters;
V² = 4.8² + 2(-0.875)0.75
V² = 23.04 - 1.31
V² = 21.73
V = √21.73 = 4.66m/s

Can two objects be at the same distance from a single point but be in different positions? Why or why not?
Plsssss help meee
Answer:Position is an object's location in relation to a reference point. Yes. Both objects are one unit away (the same distance), but they occupy different locations in space because they are in different directions.
Explanation: Hope this helps!!
Yes it is possible for two objects be at the same distance from a single point but be in different positions.
We have two objects at the same distance from a single point but are in different positions.
We have to determine whether this statement is true or not.
What is a Reference frame?A reference frame can be considered as the coordinate frame with respect to origin of which the physical quantities such as velocity, displacement , acceleration etc. of any other object in different reference frame is measured.
According to the question -
YES, Two objects can have same distance from a single point or a reference point (say origin) and can be at different positions. For example - Two different points with Position vectors -
P(1) = i + j
P(2) = - i + j
are located. Now, distance of point P(1) from origin will be - [tex]\sqrt{1+1}=\sqrt{2}[/tex] and that of point P(2) from origin will be - [tex]\sqrt{(-1)^{2} +(1)^{2} } =\sqrt{2}[/tex]
Hence, yes it is possible for two objects be at the same distance from a single point but be in different positions.

A rock is dropped (from rest) off a bridge over the Merrimack River. The falling rock
accelerates at 10 m/s2 downward. If it takes 2.5 seconds before a splash is heard,
approximately how high is the bridge?
Answer:
31.25 meters or ~31 meters approximately
Explanation:
Let's see which of the 5 variables we are given since this is a constant acceleration problem.
[tex]v_i \ \ \ \ \ \ t \\ v_f \ \ \ \ \ \triangle x \\ a[/tex]We want to find the height of the bridge, aka the vertical displacement of the rock. Let's set the upwards direction to be positive and the downwards direction to be negative.
We are told that the acceleration is 10 m/s² downward, so we have a = -10 m/s².
We are also told that the time it takes the rock to hit the water is 2.5 seconds. Time is the same regardless of the x- or y- direction, so we can say that t = 2.5 seconds.
Now, we aren't told this directly, but we can figure out that the velocity in the y-direction is 0 m/s, since the rock is dropped from rest off the bridge. Therefore, [tex]v_i=0 \frac{m}{s}[/tex].
We want to find the vertical displacement, the height of the bridge, so we can say that [tex]\triangle x= \ ?[/tex]
We have 4 out of 5 variables:
[tex]v_i,\ a, \ t, \ \triangle x[/tex]Look through the constant acceleration equations to see which equation has all 4 of these variables. You should come up with this one (no final velocity):
[tex]x_f=x_i+v_it+\frac{1}{2}at^2[/tex]Subtract [tex]x_i[/tex] from both sides of the equation to get:
[tex]\triangle x=v_it+\frac{1}{2}at^2[/tex]Substitute in our known variables and solve for delta x.
[tex]\triangle x=(0\frac{m}{s})(2.5s) + \frac{1}{2} (-10\frac{m}{s^2})(2.5s)^2[/tex]0 m/s multiplied by 2.5 s is 0, so we have:
[tex]\triangle x =\frac{1}{2} (-10)(2.5)^2[/tex]Evaluate the exponent first and multiply the terms together.
[tex]\triangle x =(-5)(6.25)[/tex] [tex]\triangle x =-31.25[/tex]The vertical displacement is -31.25 meters from the rock's starting position, so we can say that the height of the bridge is 31.25 meters, which is approximately 31 meters tall.
Answer:
31 meters

A toy train engine is rolling freely at a constant speed on a level piece of track. The train engine
collides with a stationary truck, and joins with it. Before the collision the train engine is travelling at
0.30 m/s, and has a mass of 700g. If the stationary truck has as mass of 400g. calculate the speed
of the joined engine and truck immediately after the collision.
(PLEASE answer with working).
Answer:
v₃ = 0.19 [m/s]
Explanation:
To solve this problem we must use the principle of conservation of the linear momentum, which is defined as the momentum before the collision is equal to the momentum after the collision.
ΣPbefore = ΣPafter
[tex]P=m*v[/tex]
P = momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
Let's imagine that the toy train moves to the right, this movement is taken as positive.
[tex](m_{1}*v_{1})+(m_{2}*v_{2})= (m_{1}+m_{2})*v_{3}[/tex]
where:
m₁ = mass = 700 [g] = 0.7 [kg]
v₁ = velocity = 0.3 [m/s]
m2 = mass = 400 [g] = 0.4 [kg]
v₂ = 0 (stationary truck, there is no movement)
v₃ = final velocity of the joined engine and truck.
Now replacing:
[tex](0.7*0.3)+(0.4*0)= (0.7+0.4)*v_{3}\\0.21 = 1.1*v_{3}\\v_{3}= 0.19 [m/s][/tex]

At a picnic, there is a contest in which hoses are used to shoot water at a beach ball from three different directions. As a result, three forces act on the ball, F1, F2, and F3. The magnitudes of F1 and F2 are F1=50.0N and F2=90.0N. F1 acts under the angle of 60degrees with respect to the x axis and F2 is directed along the x-axis. Find the magnitude and direction of F3 such that the resultant force acting on the ball is zero.
Answer:
F₃ = 122.88 N
θ₃ = 20.63°
Explanation:
First we find the components of F₁:
For x-component:
F₁ₓ = F₁ Cos θ₁
F₁ₓ = (50 N) Cos 60°
F₁ₓ = 25 N
For y-component:
F₁y = F₁ Sin θ₁
F₁y = (50 N) Sin 60°
F₁y = 43.3 N
Now, for F₂. As, F₂ acts along x-axis. Therefore, its y-component will be zero and its x-xomponent will be equal to the magnitude of force itself:
F₂ₓ = F₂ = 90 N
F₂y = 0 N
Now, for the resultant force on ball to be zero, the sum of x-components of the forces and the sum of the y-component of the forces must also be equal to zero:
F₁ₓ + F₂ₓ + F₃ₓ = 0 N
25 N + 90 N + F₃ₓ = 0 N
F₃ₓ = - 115 N
for y-components:
F₁y + F₂y + F₃y = 0 N
43.3 N + 0 N + F₃y = 0 N
F₃y = - 43.3 N
Now, the magnitude of F₃ can be found as:
F₃ = √F₃ₓ² + F₃y²
F₃ = √[(- 115 N)² + (- 43.3 N)²]
F₃ = 122.88 N
and the direction is given as:
θ₃ = tan⁻¹(F₃y/F₃ₓ) = tan⁻¹(-43.3 N/-115 N)
θ₃ = 20.63°
