Answer:
For the purposes of your question, we can think of speed and velocity as being the same thing. Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.
Explanation:
Answer:
In a standing sound wave in a pipe, nodes are regions of mean atmosphere pressure and low displacement.
acceleration is considered to describe an increase or positive change of speed or velocity But deceleation is considered to describe a decrease or negative change of speed or velocity
Answer:
0.0196J
Explanation:
KE equation is 1/2*m*v^2
when pluged in above numbers...
0.5*0.00245*4*4=0.0196J
