If you increased the amount of force applied on your chosen Item, rate of increase of its velocity with time will increase.
What is force?An object's push or pull is seen as exerting a force. The interaction of the objects produces push and pull. You can also use words like stretch and squeeze to describe force.
The definition of force in physics is: the push or pull on a mass-containing item changes its velocity.
An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.
So, if you increased the amount of force applied on your chosen Item, its acceleration will be increased and rate of increase of velocity with time will increase.

You are given directions to a friend’s house from your school. They read: “Go east one block, turn north and go 4 blocks, turn west and go 1 block, then go south for 2 blocks.” Using your school as the origin, draw a map of these directions on a coordinate plane. What are the coordinates of your friend’s house?
Answer:(0,2)
Explanation:
Take origin (0,0) as point A and when you move one block east to point B then coordinates becomes (1,0)
Now you move 4 blocks north to point C then the coordinates of point C becomes (4,1)
Similarly, You move 1 block west to point D such that its co-ordinates becomes (0,4)
Finally you move from D to E, 2 blocks south such that point E becomes (0,2)
So, E is the friend's house and its coordinates are (0,2)

you throw a snowball horizontally. it hits a target 2 meters away. you notice that it hit .9 m below were u aimed. with what horizontal velocoty did you throw the ball
Answer:
The target is 2 meters ahead of you.
If you throw the snowball with a velocity S, then the time that the snowball will need to hit the target is:
2m/S = T
Now let's analyze the vertical problem.
The only force acting on the snowball is the gravitational force, then the acceleration will be -g = -9.8m/s^2.
a(t) = -9.8m/s^2
For the vertical velocity, we need to integrate over time and get:
v(t) = (-9.8m/s^2)*t + v0
Where v0 is the initial vertical velocity, in this case is zero because the ball is thrown horizontally.
v(t) = (-9.8m/s^2)*t
For the vertical position, we integrate again over time.
p(t) = (-4.9m/s^2)*t^2 + p0.
Now, we know that when the ball hit the target, it hits 9 meters below the desired point (where the desired point is p0), so p(2m/S) = p0 - 9m.
Then we have:
(-4.9m/s^2)*(2m/S)^2 = -9m.
We need to solve this for S.
(-4.9m/s^2)*4m^2/-9m = S^2
2.178 m^2/s^2 = S^2
√(2.178 m^2/s^2) = S = 1.48 m/s
The horizontal velocity is 1.48 m/s

Сл A dense nucleus with protons and neutrons in the center of the atom. The electrons are found in "electron clouds" which surround the nucleus. Electron cloud show where electrons are likely to be, but not exactly where they are.
Explanation:
1 Solid ball, no subatomic particles. This model was proposed by some Greek Philosophers and John Dalton in 1803. That matter was made up of small indivisible substances called atoms.
4 Solid ball of positive materials with electrons scattered throughout. (Plum Pudding Model). This model was proposed by JJ Thomson in 1904. That the atom contained a large positively charged ball with negative charges scattered about.
3 # The atom is mostly empty space. A dense nucleus with protons and neutrons is in the center and electrons travel around it randomly. This model was proposed by Ernest Rutherford in 1911. The center of the atom was dense and positively charged with protons and neutrons surrounded by electrons orbiting it and most of the space between the nucleus and the electron orbit empty.
2 A dense nucleus with protons and neutrons is in the center of the atom. The electrons travel around the nucleus in distinct energy levels. This model was proposed by Niels Bohr in 1913. This was due to the fact that atoms only emit light at certain wavelengths which would imply that they have discrete energy levels which the electrons are contained in.
Сл A dense nucleus with protons and neutrons in the center of the atom. The electrons are found in "electron clouds" which surround the nucleus. Electron cloud show where electrons are likely to be, but not exactly where they are. This model was proposed by Erwin Schrodinger in 1926 through the solution of the Schrodinger wave equation. The position of the electron is assumed to to be a probability in an electron cloud.
(02.04 LC) Which statement best describes the rate of dissolving? (2 points) Group of answer choices All substances dissolve at the same rate. All substances dissolve at a fast rate. The rate of dissolving may be fast or slow. Rates of dissolving are usually slow.
Answer:
C. The rate of dissolving may be fast or slow.
Explanation:
When a solute is added to a solvent, the rate of dissolving may be fast or slow. This is determined by the temperature of the solvent.
A high temperature of solvent can cause an increase in the rate of dissolving a solute or substance in it, while a low temperature of solvent causes a decrease in the rate of dissolving a solute or substance in a solvent.
Therefore, the rate of dissolving may be fast or slow.

2) The decomposition of radioactive elements causes heat in the interior part of the Earth
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core
5) The process repeats as cycle.
Explanation:
Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .
The process of mantle convection start with
1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core, cools down by conduction and convection of heat.
5) The process repeats as cycle.
The proper and correct arrangement of events in the mantle convection process are:
1. The decomposition of radioactive elements causes heat in the interior part of the Earth.
2. Heat moves to the core
3. Heat slowly rises to the mantle and creates convection current.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process repeats as a cycle.
Convection is considered to be one of the most efficient ways through which heat is transported from the interior of planet Earth to the surface.
Mantle convection can be defined as the very slow transfer of heat due to the movement of Earth's solid silicate material within the mantle.
Basically, the slow creeping of the mantle causes a transfer of heat from the white-hot core to the brittle lithosphere during mantle convection.
Furthermore, the heating of the mantle takes place from below (the core) and it rises upward in hotter regions while it sinks down in colder regions.
The proper and correct arrangement of events in the mantle convection process are:
1. Heat is caused in the interior part of the Earth due to the decomposition or decay of radioactive elements.
2. Heat moves to the core.
3. Heat slowly rises from the Earth's core to the mantle and creates convection current in the asthenosphere, which is the plastic layer of the mantle.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process is then repeated as a cycle.

Answer:
B
Explanation:
Compression is the region of high pressure in a medium caused by a pressure wave.
What is Compression?When a physical force presses inward on an object, causing it to become compacted, that is when compression force (also known as compressive force) happens. The atoms and molecules of the item move around in relation to one another throughout this process. Depending on the kind of material receiving the compressive stress, this change may be either temporary or permanent. Depending on the direction or location of the compressive force imparted to the object, other outcomes may also ensue.According to Newton's Third Law of Motion, there is an equal and opposite reaction force for every action force. Both ends of an object that is lying on a surface are subjected to the same amount of compression force.The physical shape of the spring gets compacted as compression force is applied to it. The spring immediately extends outward and returns to its original shape when the compression is released. This can be a dynamic reaction, depending on the amount of force used and the spring's own malleability.To learn more about compression, refer to https://brainly.com/question/7602497

Explanation:
When the light turns green, Mark accelerates straight down the road at 1.8 m/s2 for 8 seconds. What is his final velocity at the end of those 8 seconds?
Answer:
14.4m/s
Explanation:
To calculate the final velocity (V), we use the formula:
v = u + at
Where; v = final velocity (m/s)
u = initial velocity (m/s)
a = acceleration (m/s²)
t = time (s)
According to the provided information in this question, v = ?, u = 0m/s, a = 1.8m/s², t = 8s
Hence, v = u + at
v = 0 + (1.8 × 8)
v = 0 + 14.4
v = 14.4m/s
Therefore, his final velocity at the end of those 8 seconds is 14.4m/s.
A 0.660 kg ball is dropped from rest from the top of a building and falls for 5.65 seconds. How tall was the building ?
Answer:
The height of the building is approximately 156.58 m
Explanation:
The mass of the ball dropped from rest from the building top = 0.660 kg
The time in which the ball falls, t = 5.65 seconds
The height, h, of the building is given from the following equation of motion;
h = u·t + ¹/₂·g·t²
Where;
u = The initial velocity of the ball = 0 m/s
g = The acceleration due to gravity = 9.81 m/s²
Plugging in the values, we have;
h = 0 × 5.65 + ¹/₂ × 9.81 × 5.65² ≈ 156.58 m
The height of the building, h ≈ 156.58 m.

sliding friction (1) between the car and the ground is?
Answer:
0.07
Explanation:
Huge Brain
Coefficient of friction between the car and the ground will be 0.07.
Given in the question,
Mass of the car 'm' = 3000 kgForce 'F' by which the car is pulled = 11000 NAcceleration 'a' by which the car gets accelerated = 3 meters per second²Force applied on the car by which the car is accelerated,
F = ma
= 3000 × 3
= 9000 N
Force [tex]F_k[/tex] to overcome the friction = 11000 - 9000
= 2000 N
Gravitational force F' on the car = mg
= 3000(9.8)
= 29400 N
Since, [tex]\mu_k=\frac{F_k}{F'}[/tex]
[tex]=\frac{2000}{29400}[/tex]
[tex]=0.068[/tex]
≈ 0.07
Therefore, coefficient of friction between the car and the ground will be 0.07.
