Explanation:
F = m a
F= 4.0×4.0
F= 16 N
......................................................................................................
F= ma
25= m × 4.998
m= 25/4.998
m= 5.002 kg
......................................................................................................
F=ma
53= 3 × a
a= 53/3
a= 17.666 m/s
Divide 2500 g by 500 cc. The quotient is 5 g/cc ... the density.
Answer:
d = 0.71 meters
Explanation:
It is given that,
Charge 1, 
Charge 2, 
Electrostatic force between charges, F = 9 N
Let d is the distance between the charges. The electrostatic force between the charges is given by the product of charges and divided by square of distance between them. Mathematically, it is given by :
d = 0.71 meters
So, the distance between the charges is 0.71 meters. Hence, this is the required solution.
The Sun can explode in a supernova. Around the time that sun (massive star) burning finishes, the inert core of Iron in very massive stars will collapse and the star will explode as a supernova.
When the sun explode, their inert iron cores often collapse into an extremely dense neutron star.
In a massive star, hydrogen fusion in the core is accompanied by other different fusion reactions involving heavier elements.
When the core of a massive star dies during a supernova, The supergiant will explodes as a supernova.
