To solve this question, we use the wave equation which is:
C=f*λ
where:
C is the speed;
f is the frequency;
λ is the wavelength
So in this case, plugging in our values in the problem. This will give us:
C = 261.6Hz × 1.31m
= 342.696 m/s is the answer.
It’s possible because of gravity.
Answer: A.
Explanation:
Máquina térmica tem como função, manter a temperatura de um dado fluído, então, a quantidade de calor desse mesmo fluído ao entrar na máquina, será igual á quantidade de calor desse fluido saindo.
Answer:
<em>15 cm</em>
<em></em>
Explanation:
Displacement is the shortest distance between the point of origin of a body in motion to the final stopping positing.
For this ant's aunt's aunt that travels from the 15.00 cm mark to the 85.00 cm mark back to the 30.00 cm mark and then finally to the 30.00 cm mark, the displacement from the starting position is..
displacement = stopping point - starting point
d = 30 cm - 15 cm = <em>15 cm</em>
