Answer:
The value of new value of angular speed of merry go round.
= 0.96 
Explanation:
Given data
r = 1.4 m
Moment of inertia 
= 265 kg - 
11 RPM
= 1.15
From conservation of momentum principal
------- (1)
Put all the values in equation (1)
265 × 1.15 = 317.92 ×
= 0.96
This is the value of new value of angular speed of merry go round.
Since an alpha particle has 2 protons and no negative particles (electrons) to balance the net charge, its charge is
Q=2(1.6e-19)=3.2e-19C.
The force on a charged particle is F=QE so
(3.2e-19C)(600N/C)=1.92e-16N
If an object is not at Absolute Zero, then it is
absorbing and radiating thermal (heat) energy.
UV rays have the lowest energy, (highest wavelengths)
Answer:
Ferromagnetism, physical phenomenon in which certain electrically uncharged materials strongly attract others. Two materials found in nature, lodestone (or magnetite, an oxide of iron, Fe3O4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets.
Hope this help :)
