Two small boats are in a lake. An observer on the shore sees the boats moving with the same velocity, 1 m/s due east. The mass of boat A is 10 kg; the mass of boat B, 5 kg. The momentum of Boat A is

The momentum of the boat A is 10 kg.m/s.

Explanation:

Given;

velocity of the two boats, V = 1 m/s

mass of boat A, mₐ = 10 kg

mass of boat B, mb = 5 kg

Linear momentum is given by the product of mass and linear velocity.

The momentum of the boat A is given by;

Pₐ = mₐv

Pₐ = 10 x 1

Pₐ = 10 kg.m/s

Therefore, the momentum of the boat A is 10 kg.m/s.

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.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
