Ameteoroid passes through a position in space where its speed is very small relative to earth's and it is at a perpendicular distance of 19 earth radii above earth's surface. the meteoroid is moving in such a way that earth captures it.

what is the speed of the meteoroid when it is one earth radius above the ground

Explanation:

If we call 1 the position in space where the meteoroid of mass m speed is very small relative to Earth's (whose mass is and radius is ) and it is at a perpendicular distance of above Earth's surface, and 2 the position when it is above the ground, then, since in this case mechanical energy is conserved, we can write:

which means:

where K is the kinetic energy and U the gravitational potential energy. Since we can write:

which means:

And since (the distance of an object to the center of the Earth is Earth's radius plus the height of the object), we have:

This for our values is:

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
