A. It moved from 3 cm to 10 cm at a constant speed of 2 cm/s.

Explanation:

Just took the quiz.

It moved from 3 cm to 6 cm at a constant speed of 3 cm/s.​ This  statement accurately describes the motion of the object in the graph above

An object is said to be in motion , if its position changes with respect to its surroundings and time.

A. Object's motion is from 3 cm to 10 cm at a constant speed of 2 cm/s

let us check

time = 7 sec

distance = 10 - 3 = 7 sec

speed = distance / time = 7/7 = 1 m/s

wrong option

B. Object's motion is from 0 cm to 6 cm at an average speed of 1 cm/s.

distance = 6 cm

time = 7.5 sec

speed = 6/7.5 = 0.8 m/s

wrong option

C. Object's motion is from 0 cm to 10 cm at an average speed of 2 cm/s.

distance = 10 cm

time = 9 sec

speed = 10 / 9 = 1.11 m/s

wrong option

D.  Object's motion  is from 3 cm to 6 cm at a constant speed of 3 cm/s.​

distance = 6-3 = 3 cm

time = 7.5 - 6.5 = 1 sec

speed = 3 /1 = 3 m/s

correct option  D. It moved from 3 cm to 6 cm at a constant speed of 3 cm/s.​

The conventional wisdom of the digital era is that journalists can now know their audiences in far more intimate detail than at any other time in the history of the profession. Previously, journalists based their audience knowledge primarily on their closest social circles. Now, new tools can help them solicit readers’ feedback, analyze and understand readers’ behavior, and open new channels for conversation. These new capabilities promise to shine a light on the abstract audience — making one’s readers present, quantified and real

Newton's second law and kinematics allow to find the result for the velocity at the point of reaching the child's net is:

           v = 23.7 m / s

Newton's second law states that the net force is proportional to the mass and acceleration of the body.

              ∑ F = m a

Where F is the force, m the mass and the acceleration of the body.

In the attachment we can see a free body diagram of the system, where the positive direction is up.

              F -W = m a

Weight is

             W = m g

             [tex]a = \frac{F}{m} - g[/tex]  

Let's calculate

             [tex]a= \frac{30}{70} - 9.8[/tex]  

             a = -9.37 m / s²

Negative indicates downward direction.

Kinematics studies the movement of the body, let's look for speed.

           v² = v₀² - 2 a (y-y₀)

Where v is the speed, v₀ is the initial speed, a tha acceleration ang (y-y₀) is the eight.

As the child is released, his initial velocity is zero, upon reaching the floor his height is zero and his initial height is I = 30 m.

           [tex]v= \sqrt{2 a y_o}[/tex]

Let's calculate

           v = [tex]\sqrt{2 \ 9.37 \ 30}[/tex]  

          v = 23.7 m / s

In conclusion using Newton's second law and kinematics we can find the velocity at the point where the child reaches the net is:

The velocity of the child before hitting the ground is 22.596 m/s.

The given parameters;

The weight of the child acting downwards is calculated as follows;

W = mg

W = 70 x 9.8

W = 686 N

The net force on the child is calculated as follows;

∑Fₙ = 686 N - 90 N

∑Fₙ = 596 N

The acceleration of the child is calculated as follows;

F = ma

Answer:

Energy is released or absorbed

The process is reversible

Phase change can be described as:

The physical process of changing a medium's state from one to another is known as a phase transition (or phase change) in the domains of chemistry, thermodynamics, and other related sciences.

The phrase is frequently used to describe transitions between the three fundamental states of matter—solid, liquid, and gas—and, in rare instances, plasma.

The physical characteristics of a phase of a thermodynamic system and the states of matter are constant. Certain properties of a given medium change during a phase transition as a result of a change in the environment, such as temperature or pressure. This change can be discontinuous.

Hence, Phase change can be described as:

Energy is released or absorbed and the process is reversible.

The motorized toy boat experiences a net force of 0 N between 4 s and 8 s.

The motorized toy boat moves at 8 m/s (u) at 4 s and at 8 m/s (v) at 8 s. We can calculate the acceleration (a) in that period using the following kinematic expression.

Answer:

No

Explanation:

Answer:

1 / 3 or 0.33

that is if you meant that the object accelerates at 3 m / s² not 3 m / s

for the unit of acceleration is m / s²

Explanation:

m = ?

a = 3

f = 1N

where;

m = mass ( kg )

a = acceleration ( m / s² )

f = force ( N )

from all the parameters we are given, we can use Newton's second law of motion to solve it

that is;

a = f / m

to make m the subject of the formula, we have to cross multiply to give us;

m( a ) = f

divide through by a to give us;

m ( a ) / a = f / a

therefore,

m = f / a

so, we substitute our values to give us;

m = 1 / 3

therefore. m = 1 / 3 or 0. 33

Since both heat and work can be measured and quantified, this is the same as saying that any change in the energy of a system must result in a corresponding change in the energy of the surroundings outside the system. In other words, energy cannot be created or destroyed.

Answer:

Explanation:

See attachment.

a  NO - it depends on distance between the masses, also.

The gravitational force between two objects depends only on their masses.

b  YES - see attachment

The gravitational force between two objects increases if the mass of one object increases.

c. No - it decrease

The gravitational force between two objects increases if the distance between the objects decreases.

d. It appears the answer is incomplete (stops at . . ., no . . ).  Otherwise I say YES.

Any two objects that have mass also have a force of gravity acting between them, no

The wavelength and the frequency of the light are inversely proportional to each other, the multiplication of the wavelength and the frequency of the light is equal to the speed of the light.

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 problem we have to find out how are wavelength, frequency, and energy-related to photons of light,

The relationship between the wavelength and the frequency of light is inverse, and the product of the wavelength and the frequency equals the speed of light.

Given : A car starts from rest and retains the acceleration of 4m/s² in 20 second. Calculate its final velocity.

Solution : As we know that a car starts from rest so it's initial velocity should be 0 m/s. Acceleration is 4 m/s² and time taken is 20 sec. So, we need to calculate it's final velocity which we can get it usi g the first equation of motion.

First Equation of Motion : v = u + at

Putting all the required values in the formula we will get v
