Question

Hey guys..❤️❤️ answer this ✌️✌️​

Answer 1

Explanation:

c; is the answer because cosQ =B/H

Answer 2

Answer:

let a block of mass m is placed on smooth wedge of inclination at theta

here the system is accelaerated horizontally,it means that block doesnot sleep on the wedge

F=MA component resolved in two ma costhetta and ma sintheta

ma cos theta=mg sintheta

therfore a=gtan theta (1)

N= mgcos theta + masin theta (2)

substituting (1) into (2)

N=mgcos theta +m(gtan theta) sin theta

N=mgcos theta +mg(sin theta/costheta) sintheta

N =mgcos²theta+mgsin²theta

sin theta

mg/costheta *

(cos²theta+sin²theta)

N= mg/ costheta

so thr correct option is(c)

HOPE IT HELP
