Object at rest :
*An object is said to be at rest if it does not change its position with respect to its surroundings with time.
Object at motion:
*An object is said to be in motion if the position changes with respect to it surrounding and time.
Answer:
Objects at rest: Objects at rest are ones that have no motion in them and will be stable in the same position. They have potential energy.
Objects at motion: Objects at motion are ones that are constantly in motion and a consistent velocity until they are acted upon by an unbalanced force. They have kinetic energy.

What happens to acceleration when mass is increased
Answer: acceleration will slow down.
Explanation: Since mass is inversely proportional to acceleration, if you increase the mass at a given force the rate of acceleration slows.

Which velocity graph shows the car moving toward the right (away from the origin) at a steady (constant) velocity? 
Explanation:
[tex]\text{Velocity is defined as the average displacement per unit time.}[/tex]
[tex]\text{Since the car is moving at a steady velocity, the velocity does not change over time, it shows a horizontal line on the }v-t\text{ graph}[/tex]
[tex]\text{Therefore, only option 2,5,8 matches this requirement.}[/tex]
[tex]\text{Since the car is moving to the right, which is defined as the positive direction in this question, the velocity (}v\text{) is also positive.}[/tex]
[tex]\text{Therefore, only option 5 is correct.}[/tex]
The graph marked with number [5] is the correct graph.
We have a Car.
We have to select the graph which shows that the car is moving toward the right (away from the origin) at a steady (constant) velocity.
What is the acceleration of body moving with constant velocity ?The acceleration of the body at constant velocity is 0.
According to the question -
For constant velocity, the acceleration of the car will be zero. Now, if we plot the velocity - time graph for this motion considering that the car is moving away from the origin, then the graph marked with number [5] will be the correct choice since the velocity is constant (say v) throughout the time and the motion is along right of origin.
Hence, the graph marked with number [5] is the correct graph.

15-3y=8
Solve for Y
Round to TWO decimal points
Answer: y = 2.33
Explanation:
Given expression
15 - 3y = 8
Subtract 15 on both sides
15 - 3y - 15 = 8 - 15
-3y = -7
Divide -3 on both sides
-3y / -3 = -7 / -3
[tex]\boxed{y=2.33}[/tex]

1. State Newton's third law of motion and write any three applications of it
Answer:
1)When a bullet is fired from the gun with a certain force (action) as a reaction an equal and opposite force is exerted on the gun. 2)when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
Newton's Third law: when object A exerts force on object B, object B simultaneously exert oppositely directed force of equal magnitude on object A.
1)When a bullet is fired from the gun with a certain force (action) as a reaction an equal and opposite force is exerted on the gun.
2)when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

Answer:
Here,
density (d) = 1000 kg/m^3
gravity (g) = 10 m/ s^2
height (h) = 2m
Now,
liquid pressure = hdg
=2 x 1000 x 10
=20000 N/m^2
Thus, the liquid pressure is 20000 N/m^2

9. An object which is in circular motion (moving along a circle) is said to be accelerating because it changes it's direction constantly even if it is moving with a constant speed. cuz acceleration is change in either magnitude or direction of an object with respect to time.
therefore, it's still acceleration as change in direction with time.
10. Average speed of an object can be calculated by dividing the total distance covered by an object by time taken to cover that distance.
i.e
[tex] \boxed{speed = \dfrac{distance}{time} }[/tex]it can be re- arranged to find the distance as :
[tex] \boxed{distance = speed \times time}[/tex][tex]time = \dfrac{distance}{speed} [/tex]11. speed = 20 m/s : conversion into km/h
distance covered : 4 km = 4000 m
[tex]time = \dfrac{distance}{speed} [/tex][tex]t = \dfrac{4000}{20} [/tex][tex]t = 200 \: \: sec[/tex]time taken = 200 seconds

Psycology is considered a social science while all the other choices are natural sciences.
Psychology is not considered a natural science. While it deals with the study of the human mind and behavior, psychology is generally classified as a social science rather than a natural science.
What are natural sciences?Natural science is a branch of science that deals with the study of the natural world, including the physical, chemical, and biological aspects of nature. It is a systematic and empirical approach to understanding the natural phenomena that occur in the universe. Natural sciences include subjects such as physics, chemistry, biology, geology, and astronomy, among others.
These sciences use the scientific method to investigate and explain the behavior of the natural world, relying on observation, experimentation, and analysis of data to formulate theories and laws that can explain natural phenomena. Natural science plays a critical role in our understanding of the universe and has contributed immensely to technological advancements in various fields. Therefore, option (B) is correct.

volume of box is 30cm cube breadth is 5cm height is 2m find length
Answer:
3 cm
Explanation:
I think the question have some error because if height = 2 m = 200cm.
Volume of box = l * b * h
V = 30 cm³
b = 5 cm
h = 2 cm
l = ?
V = l * b * h
30 cm³ = l * 5 * 2
l = 30 / 10
l = 3 cm
.Roshan applied a force of 144 N to the side of a cube-shaped wooden block to slide it away from himself . Assuming that he applied the force on the entire surface of the side of the cube , each side measuring 4cm , what was the magnitude of pressure applied on the said surface ?
Area=side^2=4^2=16cm^2=0.0016m^2
Force=144N[tex]\\ \sf\longmapsto Pressure=\dfrac{Force}{Area}[/tex]
[tex]\\ \sf\longmapsto Pressure=\dfrac{144}{0.0016}[/tex]
[tex]\\ \sf\longmapsto Pressure=90000Pa[/tex]
This question can simply be solved by the use of the basic formula of pressure.
The magnitude of pressure applied on the surface is "90000 Pa" (OR) "90 KPa".
The pressure is defined as the force applied per unit area in the normal direction. The pressure applied on a surface can be given by the following formula:
[tex]Pressure=\frac{Force}{Area}\\\\Pressure=\frac{144\ N}{(0.04\ m)^2}[/tex]
where,
Area of Square Surface = Side² = (0.04 m)²
Therefore,
Pressure = 90000 Pa = 90 KPa

if the light is both wave and particle ..
then when light is said to be wave and when it is said to be particle ?
Answer:
Consider electrons incident on a Young's double slit
If one slit is covered, the electrons will form a maximum, on the screen, as if they were particles incident on the screen
If both slits are open, the pattern formed on the screen will be the same as if a wave were incident on the screen, even tho electrons are slowed to the point that only 1 electron is incident on the screen at one time.
That means that the electron interferes with itself to create the interference pattern on the screen, and there is no way to determine which slit the electron went thru without destroying the interference pattern.
