B
Assume north and east as two sides of a right angled triangle. magnitude of the distance is then given by the length of the hypotenuse which is 
where a = 1.2 km north
and b = 1.6 km east
magnitude = 2 km
Direction is given by the angle between them, that is atan(a/b) = 36.86 deg north of east = 53.1 deg east of north.
Answer:
<h3>75m</h3>
Explanation:
If a cat walk 100m East, this means that it is walking in the positive x direction, the distance will therefore be +100m
If it turns around and walks 25 m west, the direction of movement is in the negative x direction i.e -25m
Taking the sum;
Displacement = +100m - 25m
Displacement of the cat = 75m
hence the cats displacement is 75m
The 1st quadrant (0-90 degrees) is the only quadrant where none of the components are negative, so that means that any angle larger than 90 degrees will result in one of the components being negative.
Answer:
mass=367kg
force=183N
acceleration =?
Now,
force=m×a
183=367×a
183÷367=a
0.49=a
acceleration =0.49m/s^2 answer!!!!
<span>Determined by the distance between objects and the difference in mass between the objects is gravity or gravitational force. Gravity is dependent on those two factors, and is what causes objects on Earth to stay on the ground. It is defined as the "pull" that an object with mass exerts on another object that makes the latter gravitate towards the former. Weight is the measure of gravitational force exerted by a mass.</span>
