Frequency of the wave below?

Physics
1 answer:
agasfer [191]3 years ago
6 0

It's hard to tell exactly what's happening in that 110 cm that you marked over the wave. What is under the ends of the long arrow ? How many complete waves ? I counted 4.5 complete waves ... maybe ?

If there are 4.5 complete waves in 110cm, then the length of 1 wave is (110/4.5)=24.44cm.

Frequency = speed/wavelength

Frequency = 2m/s /0.2444m

Frequency = 8.18 Hz

Two 4.952 cm by 4.952 cm plates that form a parallel-plate capacitor are charged to +/- 0.576 nC. What is the electric field str
horrorfan [7]

In order to solve this question, we will need to know the E-field of a capacitor

E = sigma/epsilon naught

To find sigma (charge density), we will need to divide the total charge by the area

sigma = (.576 x 10^-9)/(4.952x10^-2)^2 = 2.34 x 10^-7

E = 2.34 x 10^-7/ (8.85x10^-12) = 26541.04 V/m

A ball of mass m is thrown into the air in a 45° direction of the horizon, after 3 seconds the ball is seen in a direction 30° f
Rzqust [24]

Answer:

Velocity (magnitude) is 98.37 m/s

Explanation:

We use the vertical component of the initial velocity, which is:

v_{0y}=v_0*sin(45)=\frac{\sqrt{2} }{2}v_0

Using kinematics expression of vertical velocity (in y direction) for an accelerated motion (constant acceleration, which is gravity):

v_{y}=v_{0y}+a*t=\frac{\sqrt{2} }{2}v_0-9.8t

Now we need to find v_y as a function of v_0. We use the horizontal velocity, which is always the same as follow:

v_x=v_0cos(45\º)=\frac{\sqrt{2} }{2}v_0=v_{t=3}*cos(30\º) \\

We know the angle at 3 seconds:

v_y(t=3)=v_{t=3}*sin(30\º)\\v_{t=3}=\frac{v_y}{sin(30\º)}

Substitute  v_{t=3} in  v_x and then solve for  v_y

\frac{\sqrt{2} }{2}v_0=\frac{v_y*cos(30\º) }{sin(30\º)} \\v_y=\frac{\sqrt{6} }{6}v_0

With this expression we go back to the kinematic equation and solve it for initial speed

\frac{\sqrt{6} }{6} v_0 =\frac{\sqrt{2} }{2}v_0-29.4\\v_0(\frac{\sqrt{6}-3\sqrt{2}}{6} )=-29.4\\v_0=98.37 m/s

A layer cake profile of different soil types is exposed when we dig into the earth. Geologists reason that these layers were lai
Len [333]

The layer cake profile of different soil types having older soil type at the bottom of the layer is proved by the law of superposition.

Explanation:

The literal meaning of the word superposition means arranging one over the other. So the first generation soil or rocks will be deposited first on the mantle followed by the coming generation of soils and rocks. Due to different kinds of disasters like tides, earthquake, soil erosion etc., the new soil or rocks coming from any other region will get deposited on the surface of the old soil layer just like a layer cake format.

So the presence of older soil in the bottom most part of the mantle and the youngest soil or rock in the topmost surface of Earth is proved by the law of superposition.
