Answer:

6m/s

Explanation:

A slower moving car is traveling behind a faster moving bus. The velocities of the two vehicles are: vCG = velocity of the Car relative to the Ground = +12 m/s vBG = velocity of the Bus relative to the Ground = +16 m/s A passenger on the bus gets up and walks toward the front of the bus with a velocity of vPB, where vPB = velocity of the Passenger relative to the Bus = +2 m/s What is vPC, the velocity of the Passenger relative to the Car?

When you are is in a car moving with 12m/s speed and then there is a bus moving with 16m/s in front of you. Of course, the bus is 4m/s faster than you. if a passenger in the bus stands and runs towards the front of the bus with a speed of 2m/s , he is 2m/s ahead +the 4m/s the bus was already ahead of you, mathematically

Vpg=speed of the passenger relative to the ground

Vpb=sped of the passenger relative to the bus

Vbc=speed of the bus relative to the car

Vbg=speed of the bus relative to the ground

Vpg=Vpb+Vbc

Vbc=Vbg+Vgc

so we can conclude that

Vpc=Ypb+Vbg+Vgc

Vpc=2+16-12

Ypc=6m/s

A Styrofoam ball has just been shot straight up. Air resistance is not negligible (free body diagram)
timofeeve [1]

In a free body diagram for an object projected upwards;

  • the acceleration due to gravity on the object is always directed downwards.
  • the velocity of the object is always in the direction of the object's motion.

An object projected upwards is subjected to influence of acceleration due to gravity.

As the object accelerates upwards, its velocity decreases until the object reaches maximum height where its velocity becomes zero and as the object descends its velocity increases, which eventually becomes maximum before the object hits the ground.

To construct a free body diagram for this motion, we consider the following;

  • the acceleration due to gravity on the object is always directed downwards
  • the velocity of the object is always in the direction of the object's motion.

<u>For instance:</u>

upward motion for velocity  ↑        downward motion for velocity  ↓

                                              ↑                                                            ↓

                                              ↑                                                            ↓

acceleration due to gravity ↓

                                             ↓

                                             ↓

For her birthday, amy received flowers that had a dull red appearance. compared with the entire range of visible light waves, th
Cerrena [4.2K]
The flowers reflect relatively low frequency and low amplitude light waves.
White light contains a spectrum of colors, and red light is at the beginning of this spectrum in terms of energy. This means that it has the lowest frequency, as the energy of a wave of light is directly proportional to its frequency.
The amplitude of a light wave gives a measure of how intense the light is. A dull light means that the amplitude of the wave is low.

1.- Un barco recorre la distancia que separa Gran Canaria de Tenerife (90 km) en 6 horas. ¿Cuál es
bezimeni [28]

Answer:

The speed is 15 km/h or 4.16 m/s.

Explanation:

A boat travels the distance that separates Gran Canaria from Tenerife (90 km) in 6 hours. Which  the speed of the boat in km / h? And in m / s?

Given that,

Distance, d = 90 km = 90000 m

Time, t = 6 hours = 21600 s

Speed = distance/time

v=\dfrac{90\ km}{6\ h}\\\\=15\ km/h

or

v=\dfrac{90000\ m}{21600\ s}\\\\=4.16\ m/s

So, the required speed is 15 km/h or 4.16 m/s.

What is the velocity of a wave with a wavelength of 1.5m and a frequency of 500 Hz
Schach [20]
Wave speed  =  (wavelength) x (frequency)

                       = (1.5 m) x (500 / sec)

                       =       750 m/s .
