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)

A 3,000kg car rests on rough horizontal ground. A rope is
attached to the car and is pulled with a force of 11,000N to the
left. As a result, the car accelerates at 3 m/s2. The coefficient of
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.

If Thor throws his axe horizontally at a velocity of 50 m/s at and a height of 20 m, how long does it take before it hits the ground? (gravity is 9.8 m/s^2)
Answer:
The time taken before the axe hits the ground is 0.385 s.
Explanation:
Given;
initial velocity, u = 50 m/s
height above ground, h = 20 m
To determine the time taken before the axe hits the ground, apply the following kinematic equation;
h = ut + ¹/₂gt²
20 = 50t + ¹/₂(9.8)t²
20 = 50t + 4.9t²
4.9t² + 50t - 20 = 0
Solve this quadratic equation;
a = 4.9, b = 50, c = -20
t = 0.385 s
Therefore, the time taken before the axe hits the ground is 0.385 s.

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.

B. region of high pressure in a medium caused by a passing wave.
C. region of low pressure in a medium caused by a passing wave.
D. region of zero pressure in a medium caused by a passing wave
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.
what does boiling point mean?
Answer:
The temperature at which a liquid boils and turns to vapor.
Explanation:
Boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature. therefore the water is at its boiling point.
Answer:
When a substance starts to boil, like 212° F, that is considered boiling point.
Which of the following information about motion can be determined by looking at a position vs. time graph that is a straight line?
a.frame of reference
b.average acceleration
c.velocity
d.direction of force applied
Answer:
Velocity
Explanation:
If the position-time graph of the motion of an object is a straight line, it would mean that the object is moving uniformly. The velocity or the slope of the object is constant in such case. If the slope is curved line, it means that the velocity is not constant.
Hence, the correct option is (c).
