Answer:
Push -repulsion
Pull - attraction
Explanation:
When two magnets are brought together, a push happens when a force of repulsion is experienced where the magnets move away from each other. This means their polarity is the same and this will cause the magnet to push away from each other.
When two magnets are brought together , a pull happens when a force of attraction is experienced where the magnets move close to each other. This means their polarity is different and thus causes the magnets to pull closer to each other.
Answer:
Yes such a frame exists: a free-fall (free-float frame) frame. This frame of reference is subject only to gravity and no forces such as electromagnetic forces or nuclear forces.
-- "Declination zero" means the object is in the sky at some point directly over the Earth's equator.
-- If it's the sun and it appears to be over the equator, then that tells us that the Earth's axis is not tilted toward or away from it.
-- That in turn tells us that the Earth is at one of the two equinoxes in its orbit, either the Spring one or the Autumn one. <em> (D)</em>
-- (The first days of Summer and Winter coincide with solstices, not equinoxes.)
Answer:
acceleration = 0.8181 m/s²
Explanation:
given data
mass = 1.1 kg
apart d = 1 m
charge q = 10 μC
to find out
What is the initial acceleration
solution
we know that acceleration is
acceleration = 
.................1
here force = 
here q1 q2 is charge and r is distance and Coulomb constant k = 9 × 
Nm²/C²
force = 
force = 0.9 N
so from equation 1
acceleration = 
acceleration = 0.8181 m/s²
