Answer:
420 miles
Explanation:
3.5 * 120 mi/h = 420 miles
Answer:
75.7238461542 kg
20.4664723031 m
Explanation:
F = Force = 82 N
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Force is given by
The mass of the block is 75.7238461542 kg
Distance moved in the next 4.2 seconds
The distance moved is 20.4664723031 m
Our Sun is in the main sequence star stage.
From there our Sun will evolve to be a red giant.
When it evolves many many years from now it will engulf all of the inner planets. But don't worry, that won't happen in our lifetime!
From there the red giant (sun) will die. The death of a red giant is known as a planetary nebula. Though at the center of the nebula there is still a burning core.
When the debris flies away from the planetary nebula, our Sun will turn into a white dwarf, then the core will burn out which gives us a black dwarf.
I've provided an image of a good life cycle of the star, if you follow along with the brief description I've given you it should make sense!
If you have any questions let me know! I hope this helps!
Given that,
Initial force, F = 12 N
First initial charge, q₁ = 3C
First new charge, q₁' = 6C
Initial distance, r = 15 cm
New distance, r' = 45 cm
To find,
The new force of attraction.
Solution,
The force between two charges is given by :
Let F' is the new force.
As q₂ is same in this case.
Dividing equation (1) and (2) :
So, the new force of attraction is 2.67 N.
B as distance from the source increases, intensity stays the same
