Answer:
0.12m/s
Explanation:
v=λf
Given that, λ = 12cm = 0.12m
T = 1second
(A period T is the time required for one complete cycle of vibration to pass a given point)
frequency 'f' is unknown but we can get frequency from f = 1/T = 1/1 = 1Hz
therefore, v= 0.12 × 1 = 0.12m/s

A faster because teens what to drink it more when. they see there parents do it
Answer:
a. 25000J or 25KJ
b.2500w
Explanation:
a. since we say work is force applied in the same line or straight line
<em>W=</em><em>F(</em><em>newtons </em><em>)</em><em>*</em><em>D(</em><em>metres</em><em>)</em><em> </em>
<em>b.</em><em> </em><em>power </em><em>is </em><em>work </em><em>over </em><em>time </em>
Answer: 5 m, 2 s
Explanation:
gravity is roughly 10 m/s²downward
That means in one second, the velocity will have been reduced to zero
The average speed is (10 + 0) / 2 = 5 m/s
h = vt = 5(1) = 5 m
It will take as long to fall back to the thrower from rest so total flight is 1 + 1 = 2 s
Answer:
the object melts so the size get smaller
