Answer: (c) electric and magnetic
Explanation: Gravitational force is the weakest force considering short distances, relative to all other types of forces. However, it is strongest when considering large distances (such as astronomic scales).
Answer:
d = 1.30 mm
Explanation:
given,
wavelength of the light source (λ)= 502 nm
slits is separated (d) = ?
distance to form interference pattern(D) = 1.35 m
20 th fringe
y = 10.4 mm = 0.0104 m
now,separation between to slits
where y is the fringe width
d = 1.30 mm
separation between to slits is equal to d = 1.30 mm
Answer:

Explanation:
Let assume that the solid cylinder rolls down a frictionless incline. The translational speed can be found by using the Principle of Energy Conservation and the Work-Energy Theorem:


The translational speed is:



It's D. Gravity holds everything in place
