Question

find the HCF by prime factorisation method 1) 20,48​

Answer 1

Answer:

here is the answer:-

The HCF of 20 and 48 is 4. To calculate the HCF of 20 and 48, we need to factor each number (factors of 20 = 1, 2, 4, 5, 10, 20; factors of 48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48) and choose the highest factor that exactly divides both 20 and 48, i.e., 4..

Answer:

What are the Laws of Friction? ... The friction of the moving object is proportional and perpendicular to the normal force. The friction experienced by the object is dependent on the nature of the surface it is in contact with. Friction is independent of the area of contact as long as there is an area of contact.
