It requires 55N force to ring the bell at a hammer swing carnival game. Donald Duck can generate 250W of power while swinging th
WARRIOR [948]

Given

F = 55 N to ring the bell

P = 250 W

t = 0.85 s

Procedure

First let's calculate the force for 250W of power.

\begin{gathered} P=\frac{Fd}{t} \\ F=\frac{Pt}{d} \\ F=\frac{250W\cdot0.85s}{7m} \\ F=30.35\text{ N} \end{gathered}

With 250W it is not possible to reach the bell to ring it.

Now let's calculate the value for 500W

\begin{gathered} F=\frac{500W\cdot\text{0}.85s}{7m} \\ F=60.71\text{ N} \end{gathered}

Force is doubled when power is doubled

Which statement correctly describes sound waves
Alexxandr [17]

Answer:

Sound waves are longitudinal waves

Explanation:

Sound waves are the longitudinal waves. In longitudinal waves, the particles of the wave move parallel to the direction of propagation of waves.

It moves in the form of compression and rarefaction. When the particles are compact in a space the compression occurs while when they far apart form each other rarefaction occurs.
