The planet Mars has a mass of 6.417×1023 kg. The small moon Phobos orbits Mars in a near circular orbit at an orbital distance (from the centre of Mars to the centre of Phobos) of 9,376 km. Phobos has a mass of 1.066×1016 kg and a mean radius of 11.27 km. As an approximation you may assume the moon is spherical. It is in a tidally locked orbit so that the same side of Phobos faces Mars all the time.

Calculate the angular velocity w of Phobos

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
