Answer:
529.15 m/s
Explanation:
h = Highest point = 70000 m
g = Gravitational acceleration = 2 m/s²
m = Sulfur's mass
Since both potential and kinetic energies are conserved
The velocity at which the liquid sulfur exited the volcano is 529.15 m/s
Materials that provide effective protection against beta particles include thin aluminum sheets, as well as low atomic mass materials like plastic, wood, water, and acrylic glass for high-energy beta-radiation. These materials can also be used in protective gear, encompassing all clothing designed to shield wearers from radiation-related harm.
Hello! Thanks for sharing your query here.
To determine the change in potential energy, you would utilize the formula:
delta PE = mg*delta h
delta PE = 0.5*9.81*(2-1.8)
delta PE = 0.98 J
The kinetic energy is derived from the potential energy.
I disagree
Justification:
Fluorescent substances will emit light when exposed to ultraviolet light because the UV radiation excites their molecules.
Microwaves generate micro-waves from a different wavelength spectrum and will not excite the molecules to fluoresce
.
Transverse waves propagate in a direction that is at right angles to the movement of the particles (or the medium involved). Hence, the particles would be shifting from east to west, which is perpendicular to the north-south direction of the wave.
