Is there 16 directions i n a compass?
Going clockwise, the 16 directions are... North North North East North East East North East East East South East South East South South East South South South West South West West South West West West North West North West North North West ...and back to North again.
If you are facing east and you turn clockwise 90 degrees which direction will you be faceing?
South
What is the resultant velocity of a boat if it travels south across a river at 14 km per hr. It encounters a current flowing from east to west at 9 km per hour?
The resultant velocity of a boat is 17 km/hr and the direction of the boat is SW.
What is one half of a sphere the earth has a north and a south one of these?
Hemisphere. Earth has a North and a South Hemisphere
What is the highest number latitude can reach?
Latitude goes from zero degrees to 90 degrees north or south. The north pole is at 90 degrees north; the south pole is at 90 degrees south.
What is the resultant of 1230 ms South and 1450 ms North?
The resultant is 220 North.
What is the correct displacement for the following vectors 4 km south 2 km north 5 km south and 5 km north?
The resultant is 2 km South.
How do you find north south east west?
find the resultant of the following displacement a=20km 30south of east
Is 300kmh north the same velocity as 300kmh south?
No. Velocity is described as a speed in a certain direction. Since they are in different directions, they are different velocities.
Which of the following is the same resultant vector As 10 m north -10 m South when written as an addition problem?
0
What is resultant velocity of the plane if a plane travels 100 km per hour to the north with a headwind of 25 km per hour towards the south?
The resultant velocity of a plane is 75 km/hr.
What equilibrant force would balance forces of 12 lb east and 5 lb north acting at the same point?
the answer is 13lb south of west since the resultant is 13lb north of east. in getting the equilibrant force, just copy the resultant and reverse the direction. then that's it. .
Can resultant of three vectors be zero?
Absolutely.A very simple example: 10 pounds north, 6 pounds south, 4 pounds south.How about the resultant of 100 vectors being equal to zero, as in a tug-of-war with50 guys on each side !
What is the direction of the resulting vector if vector of 2 units North is added to a vector of 2 units South?
4
One airplane travels due to north 300kmh while the another travels due to south at 300kmh. Are their velocities the same?
no it is not, velocity includes speed and direction and while the speeds are the same the direction is not
What is the diffrerence between speed and velocity?
Velocity is speed plus its direction. -- "30 mph" is a speed. -- "30 mph north" is a velocity. -- "30 mph east" and "30 mph south" are the same speed but different velocities.
Why does the needle on a compass point north and not south east or west?
Magnetism is a hidden property in nature which manifests because of relative movement of electric charges in space. Charges are of two types. Positive and negative. We locate the presence of charges in the atom with electrons possessing negativity and with the protons having positivity. Protons are held with neutrons because of nuclear force in the nucleus. As electrons go round the core of atom, a magnetic dipole is created. This is known to be orbital magnetic dipole. Apart from this orbital movement, electrons spin and protons too spin within nucleus and so spin magnetic dipoles are also generated. Such varieties of dipoles have their resultant dipole moment in a specified orientation. Being vector, the resultant can be computed as the vector sum of all these. In some cases the resultant would become zero and in some other cases, a residual resultant dipole moment exists. Such dipole moments in different atoms of the substance as a whole may have zero resultant or net value in some direction. Now extend this idea with different materials present in the earth and there by we can get some resultant magnetic moment as a whole for the total earth. One more point is that the earth also spins in the space. So it is inevitable for earth to have a resultant magnetic moment. As earth spins about an axis which extends right from Geo north to Geo south, magnetic south is said to be induced near by Geo north and magnetic north is induced near by Geo south. The above can be easily imagined as if a bar magnet is inserted through an orange fruit. Like poles repel and unlike poles attract. This is the right reason why a pivoted compass needle, which is nothing but a magnetic needle, sets itself along north- south direction. The tip which points towards the Geo north is to be named as magnetic north pole because earth's magnetic south is said to be present near by Geo north. So no chance for the magnetic needle to stay along east-west.
