Answer:
The value is 
Explanation:
From the question we are told that
The length is 
The radius of the the solenoid is 
The number of turns per meter is 
The current through the solenoid is 
The current through the segment is 
Generally the magnetic force is mathematically represented as
At maximum 
So
Here B is the magnetic field is mathematically represented as
Here 
is the permeability of free space with value
So
=> 
So
Answer:
Explanation:
They had demoted Pluto on the basis of the discovery of Eris. They also discovered that Eris had a moon. It was thought to be much bigger than Pluto. That turned out not to be true. So having accepted Eris as a planet, they had to consider carefully what to do about Pluto. It has a gravitational constant of 0.82 m/s^2 which is 8.4% of that of our gravitational pull. and slightly more than Pluto.
Later data showed that these two objects in space were more like twins and that's what shook up the definition of a planet. You can't demote one and not the other.
Answer:
15"
Explanation:
Let x be the length of the longer part, then the length of the shorter part is 3x/5, or also x - 6
therefore we have the following equation:
3x/5 = x - 6
We can multiply both sides by 5
3x = 5x - 6*5
2x = 30
x = 30/2 = 15"
So the length of the longer part is 15"
Answer:
373 K
Explanation:
To convert from °C to kelvin, you add the value to 273
Therefore,
100°C = (100+273)K
= 373K
