because I googled it and are you going there or something
Answer:
Explanation:
The density of the magnetic flux is given by the following formula:
The normal vector A and the vector of the magnitude of the magnetic field are perpendicular, then, the angle is zero:
The magnitude of the magnetic field is calculated by using the formula for B at a distance of x to a point in the plane of the loop:
For x = 0 you have:
R is the radius of the circular loop and its values is:
Then, you replace in the equation for B with mu_o = 4\pi*10^-7 T/A:
and the density of the magnetic flux is
Explanation:
Given parameters:
Distance = 15miles north = 24140.2m
Initial velocity = 0m/s
Final velocity = 4m/s
Unknown:
Speed, velocity and acceleration = ?
Solution:
The speed is the distance divide by time. It is a scalar quantity and has no directional attribute.
Speed =
The speed of the student is 4m/s
Velocity is the displacement divided by time. It is a vector quantity which specifies the direction and magnitude;
Velocity =
The velocity of the student is 4m/s due north
Acceleration is the change in velocity with time;
To find the acceleration, we use
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance
4² = 0² + 2x a x 24140.2
a = = 0.00033m/s²
Answer:
Total time spend = 48.18 hours (Approx)
Explanation:
Given:
Total distance = 5,300 km
Average speed = 110 km / h
Find:
Total time spend
Computation:
Time = Distance / speed
Total time spend = Total distance / Average speed
Total time spend = 5,300 / 110
Total time spend = 48.18 hours (Approx)
