Answer:
A very massive main- sequence star
Explanation:
Degeneracy pressure refers to pressure expend by dense material , which is composed of fermions, which is an example of electrons in a white dwarf star. According to Pauli exclusion principle, which states that no two fermions can exist in the same quantum state, actually give details about the pressure.
When there is stellar masses that is less than about 1.44 of that of solar masses, there will be gravitational fall in the energy , and the energy will not be sufficient to produce the neutrons of a neutron star, therefore, the fall is abstruptly stopped through the electron degeneracy to form white dwarfs.this result to the creation of an effective pressure that further prevents gravitational fall.
Two things are needed to complerely describe a force: its strength and its direction. An arrow indicates both.
Answer:
p= 400.29N
........the horizontal force
Explanation:
Given data
mass=25 kg
small cube mass mass=4 kg
Us (The Coefficient of static b/w two cubes) = 0.71
to find
The horizontal force to keep the small cube from sliding downward
Solution
F=ma.........................from Newton Second law
Where F=force
a=acceleration
m=mass
we can write equation in form of acceleration
a=F/m
The acceleration on small box is same as that on the large box.
Let P be force to find.
then:
a=p/(25kg+4kg)
a=p/(29kg)m/s²
The force acting on small box:
F=ma
f=4*(p/29)N........................normal force
friction force= Us*(normal force).........where Us is coefficient of static friction.
friction force= 0.71*(4*p/29)
Now to find weight
weight= mg
weight= 4*9.8
for the object(small box) not to slide down the friction force b/w the two objects have to be exactly the same as the weight of the object.
0.71*(4*p/29)=4*9.8
solving for p(force)
p= 400.29N
........the horizontal force
Climate is a way to describe a certain areas such as temperature.
Answer:
Shorter
Explanation:
Waves become shorter and closer together as pitch increases
