The problem is asking the maximum separation between the telescope in the moon and mars. To tell you frankly, I have no idea how to calculate this by I research the answer which I will give to you and the clue that I just know is that the distance should be in kilometers and the telescopes diameter could affect the minimum separation between the two object. With that the answer would be 422,700 km
Answer:
north
Explanation:
When a charged particle moves in a magnetic field, the particle experiences a force given by the formula:
where
q is the magnitude of the charge
v is its velocity
B is the magnetic field
is the angle between the directions of v and B
In this problem,
(charge of the electron)
(strength of magnetic field)
(force)
Therefore, the velocity is
The direction of the force is perpendicular to both the direction of the velocity and the magnetic field, and it can be found using the right-hand rule:
. Thumb: direction of the force (downward) --> however the charge is negative, so this direction must be reversed: upward
- Middle finger: direction of the field (west)
- Index finger: direction of velocity --> north
So, the electron is travelling north.
Answer:
There is no displacement.
Explanation:
Because the runner is running laps and returning to the original place, there is no displacement as displacement is relative to the change in location from the original position.

Answer:
The combined mass of the two stars is 2.9417 solar masses.
Explanation:
The mathematical expression for Kepler's third law is;
=
Where: P is the period in days, a is the semimajor axis in AU, is the mass of the first star, is the mass of the second star and k is the Gaussian gravitational constant.
Given that;
P = 10 years = 3670 days (including two leap years)
a = 6.67 AU
k = 0.01720209895 rad
=
The sum of the masses of the two star can be determined by;
=
=
=
= 2.9417 solar masses
Thus the combined mass of the two star is 2.9417 solar masses.
<span>The answer is D. Electric resistance increases with an increase in the length of a wire and as a result current flow decreases. There is a direct relationship between the length of the wire and the resistance. The longer the wire, the more resistance there will be. Additionally, from Ohm's Law, current is inversely proportional to resistance. This means as the current increases, resistance decreases or vice versa.</span>
