Question

Q5. What is the difference between contact force and non contact force? Explain with the(2)
help of one example of each​

Answer 1

Explanation:

verify whether the value of x given in each case are the zeroes of polynomial or not

1.p(x)=2x+1;x=-1/2

2.p(x)=5x- pie ;x=-3/2

3.p(x)=xsq -1;x=+1

4.p(x)=(x-1)(x+2);x=-1,-2

5. p(y)=ysq ;y=0

6.p(x)ax+b;x=-b/a

7.f(x)=3xsq-1;x=-1/root3 ,2/root3

8.f(x)=2x-1,x=1/2,-1/2

Answer 2

Answer:

Explanation:

Contact force is a type of force which occurs when the two bodies are in contact with each other.

e.g. muscular force........ A man pushing a heavy stone.

Non contact force is a type of force which can occur without any physical contact with the objects.

e.g. gravitational force , magnetic force, electrostatic force.

Hope u understand.
