Mr. Harding throws a rock straight up into the air. If we assume the upward direction is positive, and ignore air resistance, at the instant the rock leaves Mr Harding's hand (the rock is no longer in contact with Mr. Harding's hand): The acceleration of the rock is downward, and the velocity of the rock is downward The acceleration of the rock is upward, and the velocity of the rock is upward The acceleration of the rock is upward, and the velocity of the rock is downward O The acceleration of the rock is zero, and the velocity of the rock is upward. O The acceleration of the rock is downward, and the velocity of the rock is upward

Can someone please tell me if I did this problem correctly? Thank you!
Please derive and proof this equation (four equation on picture)
(b) If Np is held fixed, then binomial distribution tends to Poisson distribu- tion as N is increased to infinity.
For spacelike separated events show that: i) the two events cannot be causationally related, that is, there exists a reference frame such that the two events can occur simultaneously. ii) there exists no such reference frame where the two events can occur in the same (x, y, 2) location within space.

Consider following particles for particle swarm optimization to solve optimization problem where optimal solution is on zero. Initialize velocities values as per your choice within the range of 0.1 to 0.9. the initial values of particles is 12 before starting the PSO algorithm. P1=0.2 P2=0.5 P3=.34 P4=.45 P5=0.48 a)Compute the fitness of above particles using X2+X +1 functions, sort out the particle based on fitness, most optimal particle should be on top of the list. b)Update velocity and position of each particle where w=0.7, C1=C2=1.4, rand1=1, rand2=1
