Sphere X, of mass 2 kg, is moving to the right at 10m/s. Sphere Y, of mass 4 kg, is moving to the left at 10m/s. The two spheres collide head-on. The magnitude of the impulse of X on Y is: A. twice the magnitude of the impulse of Y on X B. half the magnitude of the impulse of Y on X C. one-fourth the magnitude of the impulse of Y on X D. four times the magnitude of the impulse of Y on X E. the same as the magnitude of the impulse of Y on X

E. the same as the magnitude of the impulse of Y on X

Explanation:

Impulse is product of force and time duration of action of force . When two objects collide , two equal forces emerge at the point of contact in opposite direction . Both remain active for a fraction of a second . Since these two forces are equal and act for same period of time , the pulse of these forces two are same .

so when X collides with Y , impulse on each of them are equal , no matter what their masses or velocities are.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
