When the density and temperature at the core of the gravitationally collapsing nebula reaches values when nuclear fusion is triggered and sustained, that marks the birth of a star
Answer:
The z-component of the force is
Explanation:
From the question we are told that
The charge on the particle is
The magnitude of the magnetic field is 
The velocity of the particle toward the x-direction is 
The velocity of the particle toward the y-direction is

The velocity of the particle toward the z-direction is

Generally the force on this particle is mathematically represented as

So we have

substituting values
So the z-component of the force is
Note : The cross-multiplication template of unit vectors is shown on the first uploaded image ( From Wikibooks ).
Answer:
Option B is correct.
Explanation:
Given data
Height of the hill = AB = 1 m
Distance traveled along the rough bottom surface = AC = 2 m
Now from the ΔABC


°
We know that the coefficient of kinetic friction is


0.5
This is the value of the coefficient of kinetic friction
Thus option B is correct.
<u>Answer</u> :
atom
<u>E</u><u>xplaination</u> :
You cannot see the fundamental particles that makes up matter.
Yet, ll matter os composed of such particle called atoms.
atoms - the smallest particle of an element that retains its identity in a chemical reaction.

The total resistance referred to the HV side will be 0.36 ohm.
<h3>What is resistance?</h3>
Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.
The total resistance referred to HV side is;

Hence, the total resistance referred to the HV side will be 0.36 ohm.
