There are two types of forces
1. Physical force : in this type of forces we require direct contact between two bodies
2. Field force: here we do not requires any type of physical contact with the body
so here in this type of field force we do not required any contact but only due to field present near it the body can move
so here several examples are there
a) when a magnet is placed near a piece of iron then it will move towards the iron
b) a positively charged particle when come near another charged particle then it will get attracted or repelled.
so as per all above discussion we can say that an object can move without any direct contact
Answer: A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution, so gravity is able to pull them down out of the dispersion medium (water).
Explanation:
Answer:
I think then answer for this question is number c. the South pole
The kinetic energy of an object is directly proportional to its mass, and to the square of its velocity.
First the plane turns 100 km North, and than 200 km East. Since both the directions are perpendicular to each other, therefore we can apply the Pythagoras theorem to calculate the distance between the destination and the point where plane took off
=100^{2}+200^{2}
D=223.60 km=224 km
Therefore, The destination is 224 km from where the plane took off
