51.448 g is the required answer!
Answer:This quest took a huge leap forward in 2000 when Hubble studied the exoplanet HD 209458 b, the first extrasolar planet known to make “transits” across the face of its star. Hubble became the first telescope to directly detect an exoplanet's atmosphere and survey its makeup.

Explanation:
340 m/s / 968 cyc/s = 0.3512396... ≈ 35.1 cm
Answer:
0.855 N
Explanation:
Using
F = BILsinФ.................... Equation 1
Where F = magnitude of the force exerted on the wire, B = magnetic Field, I = current, L = Length of the wire in the magnetic Field, Ф = angle between the wire and the magnetic field.
Given: B = 0.95 T, I = 15.0 A, L = 2r, r = radius = 3.0 cm = 0.03 m L = 2×0.03 = 0.06 m, Ф = 90° (perpendicular)
Substitute into equation 1
F = 0.95(15)(0.06)sin90°
F = 0.855 N.
Hence the magnitude of force that is exerted on the wire = 0.855 N
Mechanical advantage is defined as
MA = 4
now we will have
as we need to pull up a box of weight 200 N
now by above formula we can find how much force it requires to pull up the box
so it requires 50 N force to pull the weight of 200 N
