Answer:

Stars create new elements in their cores bu squeezing elements together in a process called unclear fusion. First stars fuse hydrogen atoms into heluim. Helium atorm then fuse to create berylluim and so on until fusion in the star’s core has created every element up to icon.

An object carries a +15.5 µC charge. It is 0.525 m from a -7.25 µC charge. What is the magnitude of the electric force on the ob
lorasvet [3.4K]

Answer:

the force of attraction between the two charges is 3.55 N.

Explanation:

Given;

first charge carried by the object, q₁ = 15.5 µC

second charge carried by the q₂ = -7.25 µC

distance between the two charges, r = 0.525 m

The force of attraction between the two charges is calculated as;

F = \frac{kq_1q_2}{r^2} \\\\F = \frac{(9\times 10^9)(15\times 10^{-6})(7.25\times 10^{-6})}{(0.525)^2} \\\\F = 3.55 \ N

Therefore, the force of attraction between the two charges is 3.55 N.

What is the average total energy density in electromagnetic radiation that has an intensity of 475 W/m^2?
Andreas93 [3]

Answer:

1.6 x 10⁻⁶ J/m³

Explanation:

I = Intensity of electromagnetic radiation = 475 Wm⁻²

U = average total energy density of electromagnetic radiation

c = speed of electromagnetic radiation = 3 x 10⁸ m/s

Intensity of electromagnetic radiation is given as

I = Uc

Inserting the values

475 = U (3\times 10^{8})

U = 1.6 x 10⁻⁶ J/m³
