When supernova explodes
because of the collapsing cores, the core itself will become a neutron star or
a white dwarf without undergoing any kind of explosive transformation. The white
dwarf stars can also become supernova if they orbit another star in a binary
system and steal material from their companion. In addition, the end state of a
star, whether it will explode as a supernova become a black hole.
These types include gamma rays, x-rays, ultraviolet, infrared, microwaves and radio waves. Together with visible light, all these types of radiation make up what we call the electromagnetic spectrum - the complete spectrum of radiation.
Applying the ideal gas equation:
PV = nRT
PV = (mass/Mr)RT
mass = PVMr/RT
mass = (101325 x 4672.2 x 4) / (8.314 x 297)
= 766887.3 kg
= 7.7 x 10⁵ kg
Whenever a net force acts on an object, it means object is under acceleration which implies that there is change in the object's velocity.
The period is the time it takes any repeating process
to complete one cycle. You just told us what it is for the
pendulum . . . 6 seconds.
The frequency is the reciprocal of the period. For the pendulum,
that's
1 / (6 sec) = (1/6) per second = 1/6 Hertz .
