Answer:
compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions (or points). Usually, a diagram called a compass rose shows the directions north, south, east, and west on the compass face as abbreviated initials.
This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south.

Explanation:
A ball is dropped from rest from a high window of a tall building and falls for 4 seconds. Neglecting air resistance, the final velocity of the ball is?
Answer:
The final velocity of the ball is 39.2 m/s.
Explanation:
Given that,
A ball is dropped from rest from a high window of a tall building.
Time = 4 sec
We need to calculate the final velocity of the ball
Using equation if motion
[tex]v=u+gt[/tex]
Where, v = final velocity
u = initial velocity
g = acceleration due to gravity
t = time
Put the value into the formula
[tex]v=0+9.8\times4[/tex]
[tex]v=39.2\ m/s[/tex]
Hence, The final velocity of the ball is 39.2 m/s.

A compass taken to Earth's moon does not point in a specific direction on the moon.
What is the most likely reason for the difference between how the compass works on Earth and on the moon?
A) The moon lacks an atmosphere.
B) The moon contains no rocks that have iron.
C) The moon does not have a strong magnetic field.
D) The moon has no bodies of water.
Answer:
C.
Explanation:
The moon does not have a strong magnetic field. This is the most likely reason for the difference between how the compass works on Earth and on the moon. Hence option C is correct.
What is magnetic field ?The magnetic impact on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it while the charge is travelling through a magnetic field The magnetic field of a permanent magnet pulls on ferromagnetic substances like iron and attracts or repels other magnets. Paramagnetism, diamagnetism, and antiferromagnetism are three additional magnetic effects that a nonuniform magnetic field may have on "nonmagnetic" materials, albeit these forces are often so minute that they can only be detected by laboratory equipment. Electric currents, such those utilised in electromagnets, and electric fields that change in time produce magnetic fields that surround magnetised objects.

If a questions says "at what point does the ball stop?" what is it asking for?
Explanation:
If a question says "at what point does the ball stop?", it means we need to find the position of the ball when its final velocity is equal to 0. It can be calculated using the equation of kinematics as follows :
d = ut + (1/2) at²
and
v²-u²=2ad
Where, u is initial velocity, v is final velocity, a is acceleration, t is time and d is displacement.
1.A body of certain mass is kept at a height of 15m from the ground, taking the value of g as 10m/s find out the mass of the body when it posses the energy of 300J.
2. A boy runs at a velocity of 50m/s. If he has the mass of 50kg what will be the energy possessed by him?
Answer:
1.#potential energy = PE, m = mass in kg, g = force of gravity, h= vertical height above the ground. ** means to the power of ie exponent. * means multiply.
PE = mgh
300 = m(10)(15)
m = 300/(10)(15)
m= 2kg
2. KE = 1/2 mv**2
= 1/2(50)(50)**2

A motorboat heads due west at 15 m/s across a river that flows due south at 7.5 m/s. What is the magnitude and direction of the resultant velocity in m/s? Round off answer to 2 decimal places.
Answer:
16.77 m/s, 26.57° south of west
Explanation:
The two velocities form a right triangle. Use Pythagorean theorem to find the magnitude of the resultant velocity.
v² = (-15 m/s)² + (-7.5 m/s)²
v = 16.77 m/s
Use trig to find the angle.
tan θ = ((-7.5 m/s) / (-15 m/s))
θ = 26.57° south of west

Answer:
Speed greater than 4 m/s
Explanation:
Given that Ms. Kasper is in a panic. Her cat, Penny, is stuck in a tree and about to jump out. In order to save her cat, Ms. Kasper needs to run to the tree, 12 meters away. If it takes her cat, 3 seconds to fall, how fast would Ms. Kasper have to run to save her cat?
The distance = 12 m
Time = 3s
Speed = distance/time
Speed = 12/3
Speed = 4 m/s
Ms Kasper must run at speed more than 4m/s for her to save the cat.

What is the average velocity of an object that moves from 7.3 cm to 4.1 cm relative to the origin in 2.5 s
PLEASE HELP ME I DONT WANT TO FAIL
Answer:1 7/25
Explanation:take the total distance7.3-4.1 then divide by the total time taken
The average velocity of the object is equal to -1.28m/s relative to the origin when it moves for 2.4 seconds.
What is average velocity?Average velocity is a vector quantity and is defined as the change in position (∆x) divided by the time intervals (∆t) in which it occurs. The average velocity can be positive or negative and the S.I. unit of average velocity is m/s.
The average velocity of an object = ∆x/∆t
The average velocity of an object involves only the displacement of the object. However, the magnitude of the displacement of an object can be different from the actual path length.
Given, the displacement of the object = final position - initial position
∆x = 4.1 - 7.3 = -3.2m
The time, ∆t = 2.5 - 0 = 2.5 s
The average velocity of the object = ∆x/∆t = -3.2/2.5 = -1.28 m/s
Therefore, the average velocity of the object is -1/28 m/s relative to origin.

A soccer player kicks a ball horizontally at 25.0 m/s from a bridge, and the ball hits
the ground after 1.5 s.
2
How high is the bridge?
Answer: 11.025 meters.
Explanation:
Ok, we know that the initial velocity is only horizontal, so it does not affect the vertical problem.
Looking only at the vertical problem (because we want to know how high is the bridge) we have that:
The acceleration is the gravitational acceleration, g = 9.8m/s^2
A(t) = -9.8m/s^2
Where the negative sign is because this acceleration is downwards.
For the vertical velocity we integrate over time, as we do not have an initial vertical velocity, there is no constant of integration.
V(t) = (-9.8m/s^2)*t
For the position we integrate over time again, here the constant of integration is the initial vertical position, H, that is the height of the bridge.
P(t) = 0.5* (-9.8m/s^2)*t^2 + H.
Now we know that the ball hits the ground 1.5s after it was kicked, then:
p(1.5s) = 0m
With that we can find the value of H.
0 = 0.5* (-9.8m/s^2)*(1.5s)^2 + H.
H = 0.5*(9.8m/s^2)*(1.5s)^2 = 11.025m
