The gravitational force of the Earth exerts no torque on a satellite orbiting the Earth in an elliptical orbit. Compare the motion of the satellite at the point in its orbit nearest the Earth (perigee) to its motion at the pint in it orbit farthest from the Earth (apogee). At these two points closest to the earth:

A) the angular speed will be greatest although the linear speed will be the same. B) the kinetic energy and angular momentum will both be greater. C) None of the above. D) Both choices A and B are valid.

3) None of the above

Explanation:

In orbital motion

by lepler law:

Planet sweeps out equal area in equal of time, so angular velocity is conserved.

Angular momentum is also conserved,

so option, 3) None of the above is right.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
