One complete wave passes a putrefying pile of poached pickerel in 0.50 seconds. The piled pickerel protrude 20 cm along the beac
Ad libitum [116K]
If the wave passes the putrefying pile of a poached pickerel in 0.5 seconds, then the wave has a period of 0.5s. 

But we say that if F=1/T,
where F⇒frequency,
          T⇒period.

F=1/0.5
  = 2Hz

velocity of the wave = distance/time taken
                                = (20÷100)/0.5
                                = 0.2÷0.5
                                = 2/5

Now form the wave equation,
V=λF 
Where V ⇒ velocity of the wave.
             λ⇒wavelength of the wave.
       
So, λ=V/F

    λ = 2/5 ÷ 2
       =2/5 ×1/2
       = 2/10
       =0.2 m

The wavelength in cm is, 0.2×100 = 20 cm.

At some airports there are speed ramps to help passengers get from one place to another. A speed ramp is a moving conveyor belt
Volgvan

Answer:

It takes you 32.27 seconds to travel 121 m using the speed ramp

Explanation:

<em>Lets explain how to solve the problem</em>

- The speed ramp has a length of 121 m and is moving at a speed of

 2.2 m/s relative to the ground

- That means the speed of the ramp is 2.2 m/s

- You can cover the same distance in 78 seconds when walking on

  the ground

<em>Lets find your speed on the ground</em>

Speed = Distance ÷ Time

The distance is 121 meters

The time is 78 seconds

Your speed on the ground = 121 ÷ 78 = 1.55 m/s

If you walk at the same rate with respect to the speed ramp that

you walk on the ground

That means you walk with speed 1.55 m/s and the ramp moves by

speed 2.2 m/s

So your speed using the ramp = 2.2 + 1.55 = 3.75 m/s

Now we want to find the time you will take to travel 121 meters using

the speed ramp

Time = Distance ÷ speed

Distance = 121 meters

Speed 3.75 m/s

Time = 121 ÷ 3.75 = 32.27 seconds

It takes you 32.27 seconds to travel 121 m using the speed ramp

Two football players with mass 85 kg and 110 kg run directly toward each other with speeds 4 m/s and 7 m/s respectively. If they
sergejj [24]

Use the conservation of the momentum to answer this question:

m_1\vec v_1+m_2\vec v_2 = m\vec v\implies\\\vec v = \frac{m_1\vec v_1+m_2\vec v_2}{m_1+m_2}\\v = \frac{85kg\cdot 4 m/s+110kg\cdot (-7m/s)}{195kg}=-2.2\frac{m}{s}

The resulting speed of the two bodies will be 2.2 m/s in the (original) direction of the overweight guy (110kg). Their brains not happy about the collision either.

bekas [8.4K]

Answer:

ase of convenience, since the beneficiary by having a burrow and the shrimp benefits from knowing that there are predators nearby.

Explanation:

This exercise asks to study the dependence between two animals, the shrimp and the puffer fish.

Two types of dependency are defined:

* Complete. What is when one animal lives off the other

* Convenience if one animal does not live on the other

In this case, both the shrimp and the predator do not live on each other, since they feed independently.

So it is a case of convenience, since the beneficiary by having a burrow and the shrimp benefits from knowing that there are predators nearby.

The correct answer is: the balloon benefits by getting a burrow to live in and the shrimp knows when predators are nearby.
