A bird flies 6km east, then 4km west. Find the total distance traveled and displacement (d) after this flight.
Answers
Given :
A bird flies 6 km east, then 4 km west.
To Find :
the total distance traveled and displacement after this flight.
Solution :
a)
We know , total distance is the amount of how much ground an object has covered .
Distance = 6+4 km = 10 km .
b )
Displacement is the shortest distance from one point to another .
Now , here the object first move 6 km east then moves 4 km west .
So , his distance from the starting position is :
Displacement = 6 - 4 km = 2 km .
Hence , this is the required solution .

The results of a dart game were precise but not accurate. The accepted value of the game was the center of the dartboard. Which correctly describes the results? All of the darts hit the center of the board. Some of the darts hit the center of the board. The darts hit the same general area of the board. The darts hit very different areas of the board.
Answers
Answer:
The darts hit very different areas of the board.
Explanation:
The bullseye is the point at which darts are most accurate. There is no accuracy nor precision if the darts are neither close to the target nor to one another.
What is dart precision?The degree of similarity between several measurements is known as precision.
Even if the measurements are not exactly the right value, they are very reproducible.
Throwing darts at a dartboard can be used to demonstrate accuracy and precision.
There is precision but not accuracy if every dart lands distant from the bulls-eye but extremely closely spaced apart.
In contrast to a dart that lands far from the bulls-eye, which shows poor accuracy, a dart that hits the bulls-eye is very accurate.
Therefore, The board was struck by the darts in a variety of ways.

A rope is used to pull a 4.0 kg bucket of water upwards out of a deep well with an applied force 45 N. If starting from rest, what speed will the bucket have after experiencing this force for 2 seconds?
Answers
Answer:
v = 22.5 m/s
Explanation:
The speed of the bucket can be found using the following equation:
[tex] V_{f} = V_{0} + at [/tex]
Where:
[tex]V_{f}[/tex]: is the final speed =?
[tex]V_{0}[/tex]: is the initial speed = 0 (starts from rest)
a: is the acceleration
t: is the time = 2 s
We need to find the acceleration, it can be found as follows:
[tex] F = ma [/tex]
Where:
F: is the force = 45 N
m: is the mass = 4.0 kg
[tex] a = \frac{F}{m} = \frac{45 N}{4.0 kg} = 11.25 m/s^{2} [/tex]
Now, the speed is:
[tex] V_{f} = V_{0} + at = 11.25 m/s^{2}*2 s = 22.5 m/s [/tex]
Therefore, the speed that the bucket will have is 22.5 m/s.

Explanation:
An object is projected with initial speed v0 from the edge of the roof of a building that has height H. The initial velocity of the object makes an angle α0 with the horizontal. Neglect air resistance. If α0 is 90∘, so that the object is thrown straight up (but misses the roof on the way down), what is the speed v of the object just before it strikes the ground?
Answers
Answer:
Explanation:
Initial velocity u = V₀ in upward direction so it will be negative
u = - V₀
Displacement s = H . It is downwards so it will be positive
Acceleration = g ( positive as it is also downwards )
Using the formula
v² = u² + 2 g s
v² = (- V₀ )² + 2 g H
= V₀² + 2 g H .
v = √ ( V₀² + 2 g H )

Lists a form of potential energy followed by a form of kinetic energy
We know that,
Sound energy :
The movement of energy through object it is called sound energy. When a object produced vibration by force then it moves in wave.
Sound wave is example of kinetic energy.
Nuclear energy :
The store energy in the nucleus of the atom it is called nuclear energy. This energy released when occurs fusion and fission.
Nuclear energy is the example of potential energy
Magnetic energy :
Magnetic energy is a type of potential energy which is depend on distance and position in the magnetic field.
Electromagnetic energy :
Electromagnetic energy is light energy. it is type of kinetic energy.
Gravitational energy :
Gravitational energy is a type of potential energy. It is an energy related with gravity or gravitational force.
Elastic energy :
The store energy in elastic object it is called elastic energy. This energy is a type of potential energy.
Electrical energy :
The movement of electrons is called electrical energy. When electrons move through a wire then it is are called electricity. Electrical energy is type of kinetic energy.
Hence, Magnetic energy and electromagnetic energy form of potential energy followed by a form of kinetic energy.

2 m/s²
Explanation:
Given:
v₀ = 0 m/s
v = 20 m/s

(USE THE GRAPH) Vectors B and C and are shown in the graph. Vector B is multiplied by the scalar 92. What angle does the new vector make with the x-axis?
Answers
Answer:
The angle the new vector makes with the x-axis is 33°
Explanation:
By multiplying a vector with a scalar, we multiply the similar components of the two quantities which is the magnitude of the scalar quantity and the magnitude of the vector with the new vector formed will have a magnitude equal to the product of the two magnitudes and the same direction of the original vector as follows;
The magnitude of the vector B = 5.6
The magnitude of the scalar = 92
The product of the two magnitudes = 5.6 × 92 = 515.2
The magnitude of the new vector = 515.2
The direction of the new vector = 33° South of West
Therefore, the angle the new vector makes with the x-axis = 33°.

you throw a basketball straight up into the air with a speed of 24.5m/s. how long does it take to reach its highest point
Answers
Answer:
2.5 seconds.
Explanation:
Time equals speed divided by acceleration. gravitational acceleration is equal to 9.8 [tex]\frac{m}{s^{2} }[/tex]. You know that the speed is equal to 24.5 m/s, so plug those values into the equation.
24.5 / 9.8 = 2.5 seconds.
Hope this helps!
Answer: 2.5 s
Time=speed/acceleration
Gravitational Acceleration=9.8 m/s^2
Speed=24.5 m/s
Time=24.5/9.8=2.5 s
