Answer:
1. Speed
Explanation:
"how far an object moves in a certain amount of time"
"how far an object moves"- <em>distance</em>
"In a " - <em>over</em>
"certain amount of time" - <em>time</em>
<em>Distance over time is speed. </em>
The speed of an object is the distance the object travels in one unit of time.

Answer:
decrease by a factor 10
Explanation:
The parallax angle of a close star is given by
where
p is the parallax angle
d is the distance of the star from Earth, in parsecs
From the formula we see that the parallax angle is inversely proportional to the distance.
In this problem, the distance of the star is increased by a factor 10:
d' = 10 d
so the new parallax angle would be
So, the parallax angle would decrease by a factor 10.
Answer:
<h2>
No </h2>
Explanation:
because speed is the rate of change in the distance travelled by an object
so, speed is scalar quantity.

Answer:
<em>No, the coil will produce no flow of current or potential difference.</em>
Explanation:
Magnetic field flux is the number of magnetic field line passing through a given area. It depends on the area and the magnetic field strength through this area. For electromagnetic induction to occur, there must be a constantly changing magnetic field. This is according to Faraday's law of electromagnetic induction that states that the induced EMF is directly proportional to the rate of change in flux ΔФ/Δt, and is also proportional to the number of turns on the coil. A changing magnetic field will lead to a break in the flux linkage, which induces current or potential difference on the coil. A stationary coil through a magnetic filed will therefore produce no electric flow of current or potential difference on the coil.
