Question not making a sence, Clarify what you wana ask
work done=446.9 J . so option (c) is correct.
Explanation:
the formula for work done is given by
W= F d
F= force= mg where m= mass and g= acceleration due to gravity
F= 3.8 (9.8)=37.24 J
so W=37.24 (12)
W=446.9 J
Both matter and light have been demonstrated to exhibit wave-like and particle-like behavior.
Light as a wave: light can diffract & refract
Light as a particle: photoelectric effect, Compton scattering
Matter as a wave: Davisson-Germer experiment
Matter as a particle: find a picture of any kinematics problem in a high school physics textbook
Choice D
The particles that move in orbits of the same radius have the same momentum.
<h3>
Orbital angular momentum:</h3>
A point particle's three-dimensional angular momentum is traditionally represented by the pseudovector r p, which is the cross product of the particle's position vector r (relative to some origin) and momentum vector, which in Newtonian physics is denoted by p = mv.
L = mr
= mr²w is the particle's orbital angular momentum in units of magnitude. The part of the particle's velocity that is here perpendicular to the axis of rotation is designated as
The right-hand rule indicates the direction of the angular momentum. In isolated systems, the angular momentum is conserved.
