what is the orbital speed for a satellite 3.5 x 10^8m from the center of mars? Mars mass is 6.4 x 10^23 kg

v = 349.23 m/s

Explanation:

It is required to find the orbital speed for a satellite from the center of mass.

Mass of Mars,

The orbital speed for a satellite is given by the formula as follows :

So, the orbital speed for a satellite is 349.23 m/s.

the average speed is 24.57 km/hr

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.
