Answer:
Explanation:
Plotting the original location of the helicopter before it flies 25 km north, it would be at the origin, (0,0) then after it flies north, the y vertex gains 25 points, so it would be (0,25)
After it flies east, the x coordinate gains 5 points, so it would now be (5,25)
After it flies south, the y coordinate loses or is subtracted by 5 points. so it would now be (5,20)
After flying west, the x coordinate loses 15 points. So the final vertex would be at (-10,20)
East = Right
West = Left
South= Down
North = Up
I used mainly mathematical methods by adding and subtracting the x and y coordinate values, but this could be graphed easily since I gave the coordinates just incase!
Hope this helps!

If you touch the two probes together while the DMM is set to resistance, what will happen?
The meter will read 0 ohms
The meter will short circuit and trip a protective circuit
The meter will read infinite ohms (as high as its scale goes)
The meter will show the equivalent voltage of the meter's internal battery
If the meter's battery is good and the meter is working OK, it should read zero ohms.
Most meters have a little adjustment wheel on the side to SET the reading to exactly zero when the probes are touched together.

If an object is projected horizontally from a height of 5 m with an initial velocity of 7 m/s, what is the value of x^0?
x0=−9.8 m/s2
x subscript 0 baseline equals negative 9.8 m per s squared
x0=0
x subscript 0 baseline equals 0
x0=5
x subscript 0 baseline equals 5
x0=7
The horizontal displacement (x₀) of the object is 7 m.
The given parameters;
height of the object projection, h = 5 minitial horizontal velocity of the object, uₓ = 7 m/sThe vertical displacement equation of the object is given as;
h = vt + ¹/₂gt²
where;
v is the initial vertical velocity = 0
The time of motion is calculated as;
5 = 0 + (0.5 x 9.8)t²
5 = 4.9t²
[tex]t^2 = \frac{5}{4.9} \\\\t^2 = 1.02\\\\t = \sqrt{1.02} \\\\t = 1 \ s[/tex]
The horizontal displacement of the object is calculated as;
X₀ = uₓt
X₀ = 7 x 1
X₀ = 7 m
Thus, the horizontal displacement (x₀) of the object is 7 m.

HELP ME!!! Explain why an object moves if the action-reaction forces are equal.
Answer:
explanation is below
Explanation:
Equal and opposing forces acting on the same object are referred to as balanced forces. That is why they cancel each other out. Action-reaction forces do not cancel out because they are equal and opposite forces acting on different objects. In fact, they frequently cause movement.
Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.

H² = B² × L²
H² = (9.2)² × (5.2)²
H² = 84.64 × 27.04
H² = 2288.6656
H = √ 2288.6656
H = 47.84
Answer:
Use Pythagorean theorem
19) A² + B² = C²
5.2² + 9.2² = C²
C = √111.68
C = 10.567875...
C ≈ 10.6
21) A² + B² = C²
B² = C² - A²
B² = 7.2² - 5.3²
B = √23.75
B = 4.873397...

that the typical deceleration of a car when skidding is 45 m/s?. What can the officer estimate for the original
speed of the car?
Answer:
30 m/s
Explanation:
0^2= Vi^2+ 2 (-45)(10)
The original speed of the car is equal to 30m/s which can be calculated from the third equation of motion.
What is the equation of motion?Equations of motion explain the basic concept of motion such as the position, velocity, or acceleration of an object several times. These three equations of motion can be governed by the motion of an object in 1D, 2D, and 3D.
There are three equations of motion that can be used to find displacement(s), velocity (v or u), time(t), and acceleration(a). The third equation of motion can be represented as follows:
v² = u² + 2aS
Given, the car is deaccelerated by 45m/s².
The distance covered by the car before it stops, S = 10 m
The final velocity of the car, v = 0 as it comes to rest.
We have to calculate the initial velocity of the car by using the third equation of motion:
(0)² = (u)² + 2 (-45) × (10)
u²= 900
u = 30 m/s
Therefore, the original speed of the car is 30 m/s.

Answer:
1) ironing a shirt 2) writing on surfaces 3) working of an eraser
1. A car weighs 1000kg, you can push it .05 m/s2, how much force (F) are you applying
to the car? Here we use F=MA:
F= 1000 x .05
F= 50 newtons
Mass of the car (m) = 1000 Kg
Acceleration (a) = 0.05 m/s^2
Let the force we are applying to the car be F N.
By using the equation,
F = ma, we get
F = 1000×0.05 N = 50 N
Answer: We are applying 50 N force to the car in the direction of motion.

Which of the following statement is correct
The density of an object does not remains same if we take small quantity of that substance.
The density of an object remains same irrespective of its shape, size and quantity.
The density of an object does not remains same irrespective of its shape and size.
The density of an object remains same only if its shape and size remains same.
The density of an object remains same irrespective of its shape, size and quantity.
Explanation:
Density is an intensive property. This means that regardless of the object's shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density. It is because density in an intensive property of matter.
