Answer:
Kinetic energy, KE = 45 J
Explanation:
It is given that,
Force applied by girl on a sled, F = 15 N
It moves a distance, d = 3 m
We need to find the kinetic energy of the sled after she pulls it. We know that the work done is equal to the change in kinetic energy
(initial at rest)
So, the kinetic energy of the sled after she pulls it is 45 J. Hence, this is the required solution.

Answer:
E = 1.655 x 10⁷ N/C towards the filament
Explanation:
Electric field due to a line charge is given by the expression
E = [/tex]
where λ is linear charge density of line charge , r is distance of given point from line charge and ε₀ is a constant called permittivity and whose value is
8.85 x 10⁻¹².
Putting the given values in the equation given above
E =
E = 1.655 x 10⁷ N/C
