Answer:
I would guess the following:
The smallest part of the element is: (the atom)
proton, neutron, electron (atomic particles
The proton has mass and is positive
The neutron has mass and no charge
The electron has (very small) no mass and negative charge,
Each atomic particle has a different atomic weight.
Answer:
<em><u>Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometric optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances.</u></em>
Answer:
L = 3.35 m
Explanation:
given,
mass of the block = 0.2 Kg
spring constant = 1.40 kN/m
until spring compressed = 10 cm
inclination of ramp = 60°
now,
initial potential energy of spring = (work done by friction) + (final gravitational potential energy of block)




L = 3.35 m
