The angular diameter can be
calculated by using the formula,
Angular diameter = 57.3 x
physical diameter / distance.
The physical diameter of the
sun = 1.4 x 10^6 km.
The minimum distance of Mars
from Sun = 205 x 10^6 km
The minimum angular diameter of
the Sun as seen from Mars is:
Angular diameter = 57.3 x
physical diameter / distance = 57.3 x (1.4 x 10^6 km / 205 x 10^6 km) = 0.39
degrees.
The maximum distance of Mars
from Sun = 249 x 10^6 km.
The maximum angular diameter
of Sun as seen from Mars is,
Angular diameter = 57.3 x physical
diameter / distance = 57.3 x (1.4 x 10^6 km / 249 x 10^6 km) = 0.32 degrees

Answer:
The total energy of the object does not change is the true statement.
Explanation:
1. The force applied to the object is perpendicular to the movement so doesn't work on it, assuming the table is at the same height in all of its points the only energy we have to analyze is the kinetic energy , because the table top is frictionless by Newton's first law the velocity (v) doesn't change so the kinetic energy is constant and the total energy too.
2. There's no friction in this situation
3. As stated on 1. because the applied force is perpendicular to the movement of the object, there force doesn't work on it.
4. There are over one force on the object, the weight and the normal force table top exerts to the object.
So the only true statement is 1.

Answer:
No, the magnitude of the magnetic field won't change.
Explanation:
The magnetic field produced by a wire with a constant current is circular and its flow is given by the right-hand rule. Since this field is circular with center on the wire the magnitude of the magnetic field around the wire will be given by B = [(\mi_0)*I]/(2\pi*r) where (\mi_0) is a constant, I is the current that goes through the conductor and r is the distance from the wire. If the field sensor will move around the wire with a fixed radius the distance from the wire won't change so the magnitude of the field won't change.
