Answer:
E_total = - 50 N / A
Explanation:
The electric field is a vector magnitude whereby
E_total = Eₐ + E_b
where the bold letters indicate vectors, in this case the charges of the two objects A and B are the same and they are on the same line
E_total = - E_a - E_b
the electric field for a point charge is
E_a =
qₐ= Eₐ rₐ² / k
indicates that Eₐ = 40.0 N / C
qₐ = 40.0 0.250²/9 10⁹
qₐ = 2.777 10⁻¹⁰ C
indicates that the charge of the two points is the same
qₐ = q_b
E_total = - k qₐ / rₐ² - k qₐ / (2 rₐ)²
E_total =
we calculate
E_total = - 40.0 (5/4)
E_total = - 50 N / A
Answer:
Explanation:
the net force on the right left is 25 N and is directed upward
the net force on the left one is zero because 200N force act upward and 200N force act downward so both cancel each other and net force is zero

In order to get the best result, the student should heat the salt water mixture gently.
Application of heat will increase the amount of the kinetic energy that is available to the molecules of the salt, the particles will be moving faster and in the process they will dissolve faster. Application of heat will make the water molecules too to gain energy and take in more salts more rapidly.

<span>The star is a ball of hot gases
containing different kinds of elements at different cores. It has a very high
temperature that radiates all throughout the galaxy. The star has four
main parts; the core, photosphere, chromospheres and corona. The outer core of
a star located at the chromospheres contains mostly of hydrogen. Inside the hydrogen
is helium then carbon, oxygen, neon, magnesium silicon and the inert gas. When a
star releases energy it is due to the thermonuclear fusion of hydrogen into
helium. So the answer is fusion.</span>
