SAME:
- They both transfer energy in waves
- They both have a frequency and period
- Both are mechanical waves and require a medium
DIFFERENT:
- Transverse waves move in a perpendicular direction
- Longitudinal waves move in a parallel direction
Answer:
Explanation:
given,
mass of solid sphere = M
radius = R
linear speed = v
now,
Linear Kinetic energy
...............(1)
Rotational kinetic energy
moment of inertia of the solid sphere
and v = R ω
............(2)
ration of rotational and Kinetic energy
hence, ratio of rotational to linear kinetic energy is equal to 2/5.
Answer:
Explanation:
mass of each object = m
momentum conservation: mv₁ + mv₂ = 2mv, so v = (v₁ + v₂)/2
Initial KE = mv₁²/2 + mv₂²/2 = m(v₁² + v₂²)/2
final KE = (2m)v²/2 = m(v₁ + v₂)²/4
Change in KE = m(v₁² + v₂²)/2 - m(v₁ + v₂)²/4 = m(v₁ + v₂)²/4
= m(v₁² + v₂² + 2v₁v₂)/4 = (1/2) m(v₁² + v₂²)/2 + mv₁v₂/2
Fraction loss = change in KE / initial KE = 1/2 + v₁v₂/(v₁² + v₂²)
It should be C......................
Answer:
D. Nuclear fusion
Explanation:
Nuclear fusion is a nuclear reaction where nuclei of atoms( one of low atomic number and another with a higher atomic number) join together to form a much bigger nucleus and release a lot of energy.In the sun, which is a star of course, where light is released,hydrogen is converted to helium and the process releases massive energy into space in form of heat and light.
