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.

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
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

A monorail starts from rest and accelerates at a rate of 2.2m/s2 for 10s.Then it runs at a constant speed for 74s and then slows down at a rate of 1.5m/s2
Answer:
d = 4217 m
Explanation:
Case 1.
Initial velocity, u = 0
Acceleration, a = 2.2 m/s²
Let d₁ is the distance in case 1. Using second equation of motion as follows :
[tex]d_1=ut+\dfrac{1}{2}a_1t_1^2\\\\\text{Here, u =0}\\\\d_1=\dfrac{1}{2}\times 2.2\times 10^2\\\\d_1=110\ m[/tex]
Let d₂ in the distance in case 2. Using second equation of motion as follows :
[tex]d_2=ut+\dfrac{1}{2}a_2t_2^2\\\\\text{Here, u =0}\\\\d_2=\dfrac{1}{2}\times 1.5\times 74^2\\\\d_2=4107\ m[/tex]
Total distance,
D = d₁ + d₂
D = 110 + 4107
D = 4217 m
Hence, the total distance covered is 4217 m.

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.

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

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.
