Listena projectile with mass m is fired with initial horizontal velocity vx from height h above level ground. which change would have resulted in a greater time of flight for the projectile? [neglect friction.]decreasing the mass to m/2decreasing the height to h/2increasing the initial horizontal velocity to 2vxincreasing the height to 2h

d)

Explanation:

a) decreasing the mass to m/2. FALSE. Mass doesn't influence the equations of accelerated motion.

b) decreasing the height to h/2. FALSE. From a lower initial height the projectile will reach the ground faster.

c) increasing the initial horizontal velocity to 2vx. FALSE. The horizontal and vertical components are independent, and time of flight is dependent only on vertical conditions in this case.

d) increasing the height to 2h. TRUE. From a higher initial height the projectile will reach the ground later.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
