Answer:
Yes
Explanation:
The plank (also called a front hold, hover, or abdominal bridge) is an isometric core strength exercise that involves maintaining a position similar to a push-up for the maximum possible time
The
speed of sound depends on any form of matter or medium in which sound travels
through it and depends on the amount of molecular collisions. Sound travels slowest in gas in the form of steam
because the sound has to move around the gas molecules that are far apart making
it harder for the
energy of vibrations hit the particles and make sound.
Moreover,
sound travelling through solids like ice is much faster because the particles
are closer together so the sound waves do not have to travel that far making the
number of collisions greater and sound spread more easily.
