What are the similarities and differences between light and sound waves?
OLga [1]
All waves have an amplitude, wavelength, and frequency.
Amplitude is how far away the wave moves from its resting place. When drawn on a graph, the amplitude is the distance between the upper (crests) and lower (troughs) points and their center on the wave.
Wavelength is the distance two crests or troughs are away from each other.
Frequency is the number of waves produced in a set amount of time. The unit used to measure frequency is Hertz (Hz).
With sound waves, the frequency determines the pitch. The higher the frequency, the higher the pitch, and vice versa. So, a bass drum, which has a low pitch, would have a lower frequency than a mosquito's whine, which is very high pitched.
Light waves are actually electromagnetic waves. Their frequency determines what kind of wave they are, whether it's gamma rays, ultraviolet, x-rays, or something else.

Find the acceleration of the system and the tension in the ropes for the system shown. The table mass is 30 kg and the hanging m
marusya05 [52]

The system's tension is 616 N and acceleration is 5.6 m / s^{2}

<u>Explanation:</u>

From newton’s second law of motion which state that net force acting on a body is product of mass of a body and acceleration of a body which is given as,

             F_{n e t}=m_{t o t} \times a

Where,

F_{n e t} is net force acting on body

m_{\mathrm{tot}} is mass of body

a is acceleration of body

Given values  

Table mass (m) = 30 kg

Hanging mass (m) = 40 kg

                a=\frac{F_{n e t}}{m_{\mathrm{tot}}}=\frac{m \times g}{m_{\mathrm{tot}}}

Put the value for m = hanging mass = 40 kg and g=9.8 \mathrm{m} / \mathrm{s}^{2}, we get

                  a=\frac{40 \times 9.8}{30+40}=\frac{392}{70}=5.6 \mathrm{m} / \mathrm{s}^{2}

The tension in the ropes,  T=(m \times g)+(m \times a)

Here, m as hanging mass

T = tension, N or  k g m / s^{2}

m = mass, kg  

g = gravitational force, 9.8 \mathrm{m} / \mathrm{s}^{2}

a = acceleration, m / s^{2}

          T = (40 \times 9.8)+(40 \times 5.6) = 392+224 = 616 N

With what minimum speed must you toss a 110 g ball straight up to just touch the 11-m-high roof of the gymnasium if you release
Sholpan [36]

Answer:

 v = 13.79 m/s

Explanation:

given,

mass of ball = 110 g

height = 11 m

ball is released from = 1.3 m

minimum speed = ?

using conservation of energy

Potential energy is conserved in the form of kinetic energy

P E =KE

m g h= \dfrac{1}{2}mv^2

v^2 = 2 g h

v=\sqrt{2 g h}

v=\sqrt{2\times 9.8 \times (11-1.3)}

v=\sqrt{2\times 9.8 \times 9.7}

v=\sqrt{190.12}

       v = 13.79 m/s
