I'm thinking it's a parabola since you can cover a vast amount of apace within the parabola too.

What is satellite ?

An object that has been placed into orbit in space on purpose is known as a satellite or artificial satellite. Except for passive spacecraft, most satellites feature a power generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs) (RTGs). Most satellites also include a mechanism of communicating to ground stations, called transponders. The most common satellites, small CubeSats, use a standardized bus to reduce costs and labor. Satellites of a similar type can cooperate with one another to form constellations. Satellites are made to be as light and durable as possible due to the high cost of space launch. Satellites are launched into orbit from the surface by vehicles that are high enough to prevent orbital decay caused by the atmosphere.

An observer that stands still as the electron moves by him, will observe ___.

muminat

When charge is placed near to us whether it is stationary or if it is in motion then we can say it will produce electric field.

Now when charge is in motion then it will also produce electric current

So due to a moving charge there is some magnetic field also near it

it is given as

$B = \frac{\mu_0 qv}{4\pi r^2}$

So here we can say that nearby a moving charge we must have experience the effect of electric field as well as magnetic field

so the correct answer must be

<em>B) An electric & magnetic field</em>

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their b

Ksivusya [100]

Answer:

$\omega = 2.56 rad/s$

Explanation:

As the cylinder rotates the centripetal force on all the passengers is due to normal force due to the wall

So here we can say

$N = m\omega^2 R$

now when floor is removed all the passengers are safe because here friction force on the passenger is counter balanced by the weight of the passengers

so we can say

$F_f = mg$
