For the given problem, we calculate the required time by
using the formula P = W/t.
P = [(1/2)mv_f^2 – (1/2)mv_i^2]/ t
The car accelerates from 0 -58 mph, so the power engine will
be
P = (1/2) x m x 58^2 / t = 1682 m / t
According to the problem, the engine produces full power so
the time required can be calculated as
420.5 m / 1.40 = 1682 m / t
t = 5.6 seconds
Energy remains constant is the answer you are looking for but it only applies, when no outside forces act on the object.

Magnetic field is produced by the magnet which will flow through any attractive item or even substance such as ferrofluid. Happy I could help:)
Answer:
g= 3.86 m/s^2
Explanation:
given : Kepler-12b, has a diameter that is 1.7 times that of Jupiter (R_Jupiter = 6.99 × 10^7 m), but a mass that is only 0.43 that of Jupiter (M_Jupiter = 1.90 × 10^27 kg ).
to calculate gravity we use the formula
g = GM/r^2
g = 6.67×10^-11 × 0.43×1.9×10^27/( 1.7×6.99×10^7)^2
g = 3.859 ~ 3.86 m/s^2
