Explanation:
Just did it
Answer:
The product of (wavelength) x (frequency) is always the same number ... the wave's speed.
So if the wavelength is somehow reduced to 1/4 its original length, the frequency is immediately multiplied by 4 . That's the only way their product can remain the same.
Explanation:
Answer:
Opposite direction
Skeletal
muscles arise in antagonistic pairs where the muscles contract to produce
opposite movements at the same joint. Antagonistic muscles move a body part in
one direction by contraction, the other moves that part in opposite direction.
In
addition, when a muscle contracts to produced movement, its antagonist relaxes
to allow movement to take place such as biceps muscles is a flexor muscle for
elbow joint and triceps is the antagonist.
