Answer:

Amplitude and wavelength

Explanation:

- The amplitude of a wave is the maximum displacement of the wave, measured with respect to the equilibrium position (so, for a water wave it is the maximum height of the wave relative to the equilibrium position)

- The wavelength of a wave is the distance between two consecutive crests (or throughs) of a wave. So, for a water wave, it is the distance between two consecutive waves

Therefore, in the example in the problem we have:

- 2 meters corresponds to the amplitude

- 35 meters corresponds to the wavelength

An arcade ball is thrown with an initial speed of 7.0 m/s and follows the trajectory shown. The ball enter the basket .95 second

Complete Question

The diagram for this question is shown on the first uploaded image

Answer:

x  =  4.70  \  m     ,   y =  0.2803 \  m

Explanation:

From the question we are told that

     The initial velocity of the arcade ball is  u  =  7.0 \  m/s

     The time taken by the ball to enter the basket is  t =  0.95 \ s

Generally the x -component of the initial  velocity is  

            u_x  =  7 *  cos (45)    

=>         u_x  =  4.95 \  m/s

Generally the y -component of the initial  velocity is  

            u_x  =  7 *  sin(45)    

=>         u_y  =  4.95 \  m/s

  Generally the distance x is mathematically represented as

                 x  =  u_x  *  t

=>              x  =  4.95 *  0.95      

=>              x  =  4.70  \  m    

Generally from kinematic equation the distance y is mathematically represented as

               y =  u_y * t  - \frac{1}{2} *  g * t^2

=>            y = 4.95 * 0.95  - \frac{1}{2} *  9.8 * 0.95^2

=>            y =  0.2803 \  m

Why are nonmetals more likely to react with eachother by sharing electrons
RideAnS [48]

The answer is; non-metals have a high ionization energy

This means that it would take more energy to dislodge an electron from the valence orbital than it would take to do the same to a metal atom. Therefore it would be easier to share electrons for non-metals while it would be easier to lose an electron for metals to reach a stable electron configuration.

If the organ pipe is cut in half, what is the new fundamental frequency? if the organ pipe is cut in half, what is the new funda
bogdanovich [222]

The frequency for a fundamental pipe is given as:

f = v/4L

L is equal to the length of the pipe

Since L = Lo/2 where Lo is the original length of the pipe, the new frequency would be:

f = (v/4)/(Lo/2)

f = 2 (v/4Lo)

Since v/4Lo = fo, therefore:

f = 2 fo
