Answer:
5000 m equivalent to 5 Km
Explanation:
Average velocity =
so, Displacement =Average velocity × time
We should convert Km/h to m/s so Km/h ⇒
m/s, also convert time to second so, 20min ⇒(20* 60)seconds
Displacement = (15 ×
) × (20×60) =5000m OR 5Km
Sample Response: How can magnetic and electric fields be demonstrated?
Microwave because they are powerful and available can be d answer
Answer:
On the magnitude of the charges, on their separation and on the sign of the charges
Explanation:
The magnitude of the electric force between two charges is given by

where
k is the Coulomb's constant
q1, q2 are the magnitudes of the two charges
r is the separation between the charges
From the formula, we see that the magnitude of the force depends on the following factors:
- magnitude of the two charges
- separation between the charges
Moreover, the direction of the force depends on the sign of the two charges. In fact:
- if the two charges have same sign, the force is repulsive
- if the two charges have opposite signs, the force is attractive
Answer:
The first
Explanation:
Cause it will continue in motion till another force is applied
