Answer:
impulse = force * time = 20 * 10 = 200 Ns
change in momentum = impulse = 200 kgm/s

Acoording to my brain i think that the answer would be C
Answer:
Explanation:
given,
diameter of the beam (d)= 5.85 cm
= 0.0585 m
average wavelength of the(λ) = 580 n m
angle of of spreading = ?
according to the Rayleigh Criterion the minimum angular spreading, for a circular aperture, is
the minimum angle of spreading is
The gravitational force between the two objects is given by:
where
is the gravitational constant
is the Sun mass
is the mass of Mercury
and d is the distance between Sun and Mercury. Since we know the force:
we can re-arrange the formula to find d:
