Question 1 Water: Start with the Water tab. Note that light areas represent places where the water is high (crests). Dark areas

represent low points (troughs). The water drops should already be dripping from the faucet. You can inerease their frequency and amplitude by using the Frequency and Amplitude slider. Using the controls on the far right, you can add measuring tools, add wall, add another faucet, or insert a single-slit or tw0-slit barrier. Part A What kind of wave patterns do you observe in the sink in the top view? I Part B Click on the Show Graph button in the top right corner of the window. The graph shows the moving water level, which is the actual amplitude of the waves. What general mathematical graph function does this look like? What pattern do you observe in the amplitude of these waves? Provide a hypothesis to explain this pattern in the amplitude. I Part C What happens when you increase the frequency of the water drops? What happens to the wavelength of the waves on the surface of water? PLZ ANSWER ALL FOR BRAINLIEST​

Answer:

Looks like a cosine function graph. The wave pattern is transversal waves . The faster the amplitude the higher the wave. The force of the drop hitting the water pushes the water down and out causing waves  If the water hits from a higher amplitude the waves raise bigger . When you increase the frequency of the water drops the waves move faster but no bigger.  When you increase the frequency of the water drops the wave ripples faster .

What is the wavelength of a wave whose velocity is 8 m/s and frequency is 2 waves/second?
Maru [420]

Wavelength = (speed) / (frequency)

Wavelength = (8 m/s) / (2/s)

Can you finish it off from this point ?

Define 1 unit electricity​
Tomtit [17]

Answer:

A unit is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity.

A 100-kg tackler moving at a speed of 2.6 m/s meets head-on (and holds on to) an 92-kg halfback moving at a speed of 5.0 m/s. Pa
DIA [1.3K]

Given that,

Mass of trackler, m₁ = 100 kg

Speed of trackler, u₁ = 2.6 m/s

Mass of halfback, m₂ = 92 kg

Speed of halfback, u₂ = -5 m/s (direction is opposite)

To find,

Mutual speed immediately after the collision.

Solution,

The momentum of the system remains conserved in this case. Let v is the mutual speed after the collision. Using conservation of momentum as :

m_1u_1+m_2u_2=(m_1+m_2)V\\\\V=\dfrac{m_1u_1+m_2u_2}{(m_1+m_2)}\\\\V=\dfrac{100\times 2.6+92\times (-5)}{(100+92)}\\\\V=-1.04\ m/s

So, the mutual speed immediately after the collision is 1.04 m/s but in opposite direction.

A golf club rotates 215 degrees and has a length (radius) equal to 29 inches. The time it took to swing the club was 0.8 seconds
vichka [17]

Answer:

The average linear velocity (inches/second) of the golf club is 136.01 inches/second

Explanation:

Given;

length of the club, L = 29 inches

rotation angle, θ = 215⁰

time of motion, t = 0.8 s

The angular speed of the club is calculated as follows;

\omega = (\frac{\theta}{360} \times 2\pi, \ rad) \times \frac{1}{t} \\\\\omega =  (\frac{215}{360} \times 2\pi, \ rad) \times \frac{1}{0.8 \ s} \\\\\omega = 4.69 \ rad/s

The average linear velocity (inches/second) of the golf club is calculated as;

v = ωr

v = 4.69 rad/s  x  29 inches

v = 136.01 inches/second

Therefore, the average linear velocity (inches/second) of the golf club is 136.01 inches/second
