Answer:
A
Explanation:
Every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.
What is the matter?Anything which has mass to keep the same when comparing the hardness of the solid and occupies space is known as matter, mainly there are four states of matter solid liquid gases, and plasma.
As given in the problem statement we have to find the true statement from the given options that is true for every atom of an element,
The size of an atom of an element is a very small order of magnitude so it can not be seen with a magnifying glass, therefore, option A is not the correct response.
Thus, every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.

Answer:
the velocity is 4 ms, if it asked for change it be 0 m/s but its asking for velocity so option 4, 4m/s
Explanation:
The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.
To calculate the acceleration of the object at 8 seconds, we need to look at the change in velocity over time (acceleration is the rate of change of velocity).
Given the graph, we can see that at 8 seconds, the velocity of the object is 6 m/s.
Now, let's find the change in velocity between 8 seconds and 10 seconds:
Change in velocity = Final velocity - Initial velocity
Change in velocity = 2 m/s - 6 m/s
Change in velocity = -4 m/s
Next, find the time interval between 8 seconds and 10 seconds:
Time interval = Final time - Initial time
Time interval = 10 s - 8 s
Time interval = 2 seconds
Now, calculate the acceleration:
Acceleration = Change in velocity / Time interval
Acceleration = (-4 m/s) / (2 s)
Acceleration = -2 m/s²
The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.

A projectile is fired from the ground at a velocity of 30.0 m/s, 35.0 º from the horizontal. What is the maximum height the projectile reaches in the air? How far away from the point it was fired does it hit the ground? What is the time the projectile is in the air?
Answer:
Vy = V sin theta = 30 * ,574 = 17.2 m/s
t1 = 17.2 / 9.8 = 1.76 sec to reach max height
Max height = 17.2 * 1.76 - 1/2 * 4.9 * 1.76^2 = 15.1 m
H = V t - 1/2 g t^2 = 1.2 * 9.8 * 1.76^2 = 15.1 m
Time to fall from zero speed to ground = rise time = 1.76 sec
Vx = V cos 35 = 24.6 m / sec horizontal speed
Time in air = 1.76 * 2 = 3.52 sec before returning to ground
S = 24.6 * 3.52 = 86.6 m

Answer:
Explanation:
Speed multipliers are useful when an object needs to move a further distance or at a higher speed. Some examples are wheels and axles and third class levers. Machines can be either simple or complex. Simple machines are machines that only use one type of machine, such as a lever or an inclined plane.

Determine your mass in kg noting that 1 kg is about 2.2 lbs. Then use Fg = mg to find your weight in Newtons.
Answer: see example due to variation of factor
Explanation: w = m x g
Weight= Mass (in kg) x Gravity (9.8m/s)
To get to kg from lbs take your weight divide by 2.2lbs well get you to kg
Example
Let's say a boy weighs 145lbs
145kg/2.2lbs=66kg
Now we use the equation
w=m x g
65kg*9.81m/s=637.65N
A 63 kg boy and sled are pulled along level ground with a force of 577 N. The boy and sled
are moving at a constant velocity of 2.4 m/s. What is the size of the frictional force?
Answer:
The size of the frictional force is 577 N.
Explanation:
What is frictional force?Frictional forces are exerted every time you have two surfaces sliding across one another. Friction depends on:
how rougher are the surfaces on contact;how harder you push one surface to the other.There are two types of friction:
static friction [tex]f_s[/tex];dynamic (sliding) friction [tex]f_d[/tex].Now let's attack the problem:
First, you have to write the data down:
[tex]\bullet \quad m= 63\,kg\\\\\bullet \quad F= 577\,N\\\\\bullet \quad v= 2.4\,m/s[/tex]
If the boy and the sled moves on constant velocity, Newton's First Law Of Motion states that the net force acting on them must be zero:
[tex]F_{net}=0[/tex]
Applying Newton's Second Law Of Motion, we get:
[tex]F-f_d=0[/tex]
which means that:
[tex]F=f_d[/tex]
In other words, the dynamic frictional force equals the force that moves the boy and sled. So we may write:
[tex]\boxed{f_d=577\,N}[/tex]
Conclusion: the size of the (dynamic) frictional force is 577 N.

Answer:
This section assumes you have enough background in calculus to be familiar with integration. In Instantaneous Velocity and Speed and Average and Instantaneous Acceleration we introduced the kinematic functions of velocity and acceleration using the derivative. By taking the derivative of the position function we found the velocity function, and likewise by taking the derivative of the velocity function we found the acceleration function. Using integral calculus, we can work backward and calculate the velocity function from the acceleration function, and the position function from the velocity function.Explanation:
Derive the kinematic equations for constant acceleration using integral calculus.Use the integral formulation of the kinematic equations in analyzing motion.Find the functional form of velocity versus time given the acceleration function.Find the functional form of position versus time given the velocity function.Urgent need help 100 points

Answer:
it is the dependent since it keeps changing over time get it :)
Explanation:
Explain how the basic unit are combined to give the derived units of force, velocity, pressure and work
Velocity:
Velocity is change in displacement with respect to time:
[tex]\frac{\Delta x}{\Delta t}[/tex]
Analysing the units, meters (displacement) and seconds (time) are basic units:
[tex]\frac{m}{s}[/tex]
Therefore the unit of velocity is m/s
Force:
Newton's second law of motion:
[tex]F = ma[/tex]
Kilogram (mass) is a basic unit, and accelerations unit can be found using the equation:
[tex]a=\frac{\Delta v}{\Delta t}[/tex]
Analysing the units:
[tex]\frac{\frac{m}{s}}{s}=\frac{m}{s^2}[/tex]
Therefore, the unit of force is:
[tex]kg\frac{m}{s^2}[/tex]
Pressure:
Pressure is given by the equation:
[tex]P=\frac{F}{S}[/tex] where S is area of effect, F is force
Area for a basic rectangle (geometric shape is arbitrary for dimensional analysis) is found by multiplying two lengths:
[tex][l^2]=m^2[/tex], the unit of area
Dividing the aforementioned unit of force by the unit of area:
[tex]\frac{kg\frac{m}{s^2}}{m^2}=\frac{kg}{ms^2}[/tex], the unit of pressure
Work:
Work is given by the equation:
[tex]W=\vec{F}\cdot \vec{x}[/tex], (dot product may be assumed as normal multiplication for the purposes of unit analysis)
Knowing displacement's (x) unit is m:
[tex][W]=\frac{kgm}{s^2}m=\frac{kgm^2}{s^2}[/tex], the unit of work.
