In 2014, about how far in meters would you have to travel on the surface of the Earth from the North Magnetic Pole to the Geogra
1 answer:
Answer:
267.07 km
Explanation:
We have given the radius of the earth = 6378.1 km
In 2014 the difference between the magnetic north pole and geographical north pole is 2.40°
2.40°
We know that linear distance is given by
So we have to travel 267.07 km in going from magnetic north pole to geographic north pole

Answer:
a= - 6.667 m/s²
Explanation:
Given that
The initial speed of the box ,u= 20 m/s
The final speed of the box ,v= 0 m/s
The distance cover by box ,s= 30 m
Lets take the acceleration of the box = a
We know that
v²= u ² + 2 a s
Now by putting the values in the above equation we get
0²=20² + 2 a x 30
a= - 6.667 m/s²
Negative sign indicates that velocity and acceleration are in opposite direction.
Therefore the acceleration of the box will be - 6.667 m/s² .
