2. a dog sits 1.5 m from the center of a merry-go-round. the merry-go-round is set in motion, and the dog's tangential speed is 1.5 m/s. what is the dog's centripetal
acceleration?

1.5 m/ directed towards the center of the circle.

Explanation:

Formula for Centripetal Acceleration

where v= represents the velocity of the object exhibiting circular motion and r represents the radius in which the body is doing a circular motion.

Given Parameters

v=1.5 m/s

r=1.5 m

Plugging in the values ,

= 1.5 m/ directed towards to the center of the circle.

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!

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
