The diagram on the right shows a block being pulled across a level surface by a tension force T in a rope that is at angle θ above the ground. The normal force on the block Fn and weight of the block W are also shown. Which of the following would happen if the magnitude of the tension force T stays the same, but the angle θ increases?
A. The weight of W of the object increases
B. The weight of W of the object decreases
C. The normal force Fn on the object increases
D. The normal force Fn on the object decreases.

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
