What is the frequency if 140 waves pass in 2 minutes?

Physics
1 answer:
Paha777 [63]3 years ago
8 0

Answer:

1.16 Hz

Explanation:

frequency, basically, is the number of wave on 1 second

so, in math we write like this

f = n/t

n = number of waves

t = time to do that (in sec)

f = 140/120 = 7/6 Hz

f = 1.16 Hz

How much kinetic energy does a baseball with a mass of 0.143 kg have it it is traveling at a velocity of 41.1 m/s?
vampirchik [111]

Answer:

E = 120.77 J

Explanation:

Given that,

Mass of a baseball, m = 0.143 kg

Velocity of a baseball, v = 41.1 m/s

We need to find the kinetic energy of the baseball. We know that the kinetic energy of an object is associated with its motion. It can be given by the formula as follow :

E=\dfrac{1}{2}mv^2\\\\E=\dfrac{1}{2}\times 0.143\ kg\times (41.1\ m/s)^2\\E=120.77\ J

So, the kinetic energy of the baseball is 120.77 J.

A transverse wave on a rope is given by y(x,t)= (0.750cm)cos(π[(0.400cm−1)x+(250s−1)t]). part a part complete find the amplitude
Pani-rosa [81]
The amplitude of a wave corresponds to its maximum oscillation of the wave itself. 
In our problem, the equation of the wave is
y(x,t)= (0.750cm)cos(\pi [(0.400cm-1)x+(250s-1)t])
We can see that the maximum value of y(x,t) is reached when the cosine is equal to 1. When this condition occurs,
y(x,t)=0.750 cm
and therefore this value corresponds to the amplitude of the wave.

A Perspex container has a 6 cm square base and contains
crimeas [40]

Answer:

a) V = 252 cm³

b) Vs = 72 cm³

Explanation:

a)

The volume of the water can be given by the following formula:

Volume\ of\ Water = V = (Base\ Area)(Height)\\V = (Length)^2(Height)\\V = (6\ cm)^2(7\ cm)\\

<u>V = 252 cm³</u>

<u></u>

b)

The volume of stone can be given by the change in volume of the water when the stone is dipped into it.

Volume\ of\ Stone = Vs = (Length)^2(Change\ in\ Height\ of\ Water)\\Vs = (6\ cm)^2(9\ cm - 7\ cm)\\

<u>Vs = 72 cm³</u>
