Where speed is distance/time, velocity is displacement/time.
What this means is that velocity is the length covered in relation to the starting point.
Speed is just the distance travelled no matter where you began.
When going around a circular track, you might have a speed value. However, since you get back to the same location at every lap, you have 0 velocity.
Hope I helped :)
B) It falls at a constant rate of speed.
Answer:
The electric flux through the sphere is 
Explanation:
Given

Required
Find the electric flux
Electric flux is calculated using the following formula;
Ф = q/ε
Where ε is the electric constant permitivitty
ε 
Substitute ε
and
; The formula becomes
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Hence, the electric flux through the sphere is 
Magnets don’t need to touch each other in order to be magnetic because all objects have an attraction however, the closer the magnets get, the more magnetic it is.
False because opposites attract. :)
