a. Who are the people who travel the meridian line'?

The poem also includes descriptions of individuals who have travelled the meridian line. These are the Nigerians who came together during a protracted civil war and experienced starvation, poverty, unemployment, and a lack of other fundamental necessities.

An electron travels at a speed of 2.0 x 10^6 m/s in a magnetic field of 0.5 T. Calculate the force experienced by the electron. (Given: Charge of an electron = -1.6 x 10^-19 C)

How do data travels from datacenters to your device through internet?

How do the passengers feel while travelling via hyperloop? What will be done to make it luxurious? 

On a hyperloop, the passengers feel approximately the same as riding a lift or a passenger aircraft. The cabin shows beautiful scenery and each passenger has access to his or her own private amusement systems, to let them have an easeful journey.

  1. Figure 3.64 shows the position-time graphs of three cars A, B, and C. On the basis of the graphs, answer the following questions:i) Which car has the highest speed and which is the lowest?ii) ...

Solution 

Velocity of car A = slope of x-t of A = 14-6/1.6 = 5km/hs

Velocity of car B = slope of x-t of B =14-0/1.4 = 10km/hs

Velocity of car C = slope of x-t of c = 14-2/1 =12km/hs

A) Car C has the highest speed and car A has the lowest.

B) There is no point where all three line intersect. so, all three car never meet at a same                   position. 

C) When car A passes car C, car B is at 6km.

D) Time interval= 1.2-0.6 =...

Why are sound easier to hear at night than at day time?

Due to the refraction of sound, we can hear sounds easily at night than during clear days.

On a clear day, the lower layer of the atmosphere is hotter than the layers above. Since sound travels faster in a hotter medium, its speed is greater near the surface. As a result, the waves are bent away from the surface. Thus, the intensity of the sound waves diminishes and does not seem to travel a long distance. On a clear night, the lower layer of the atmosphere is colder than the air above. Now,...

A point travelling at 20 cm/s accelerates uniformly at 5 cm/s2 . Find the distance travelled in sixth second.

Which type of wave propaates in liquid? Explain . 

The type of wave that propagates in a liquid is called a mechanical wave. Mechanical waves are waves that require a medium to propagate, meaning they need a substance to travel through. In the case of liquid, such as water, mechanical waves can travel through it.

There are two primary types of mechanical waves that can propagate in a liquid: transverse waves and longitudinal waves.

1. Transverse Waves: In a transverse wave, the particles of the medium move perpendicular to the direction of wave...

An astronaut is said to be weightless when he/she travels on a satellite. Does it mean that the earth does not attract him or her?

The sense of weightlessness in orbiting satellites is because of the lack of any contact forces. The only force that acts upon humans in space is the force of gravity, which acts at a distance; but as there is no counter-force, we do not experience the sensation of weight over there. The counter or force-of-contact is missing because everything that floats in space does so due to the acceleration due to gravity being the same. Thus, both the astronaut and the satellite have the same value of...
