Explanation:
If the two charges are point charges - i.e., they don't have a size - the force between these charges depends on the
• Magnitude if each charge, q1 and q2
• Sign of each charge (+ or -)
• Distance between the charges, r
This is essentially Coulomb’s Law:
FE = (kq1q2)/r2
For collections of charges, you need to find the electric field E, and then use this fields to find a force on a small test charge q in the field. The test charge is always small to help you map the electric field, but not disturb it.
Answer:
Time taken by the object is 0.012 s .
Explanation:
Given :
Frequency , f = 3.5 Hz .
Amplitude , A = 0.15 m .
At time t = 0 , x = 0 m.
Since , at time t = 0 , x = 0 m .
Therefore , equation of displacement is :
...equation 1.
Here , is angular frequency and is given by :
We need to find the time at which its displacement is ,
Putting all these value in equation 1 we get ,
Hence , this is the required solution.
Answer:
Emergent curriculum is an early education approach where teachers design projects unique to a child or group of kids.
Answer:
Inertia relates directly to an object's <em>mass</em>. It is its inherent property and expresses how much force is needed to bring the object to a certain level of acceleration. It is the sole factor.
Momentum relates proportionally to two factors: <em>mass</em> and <em>velocity</em>. As such, momentum is not an inherent property of an object but a measure dependent on it current velocity, in addition to its mass.
