Answer:

Potential energy of the system increases relative to infinity.

Explanation:

Potential energy of two point charge is defined as,

U=\frac{q_{1}q_{2} }{4\pi\epsilon_{0}r^{2}}

Here, q_{1}and q_{2} are two point charge, r is the distyance between the two charges.

Now according to the question charge is of equal magnitude but opposite sign.

Therefore potential energy,

U=\frac{q(-q) }{4\pi\epsilon_{0}r^{2}}\\U=- \frac{q^{2}  }{4\pi\epsilon_{0}r^{2}}

From the above formula if the distance increases then magnitude of potential energy decreases.

And due to presence of negative charge magnitude of Potential energy is increases with increasing distance.

Therefore, the potential energy is increasing if we move two opposite charge farther.

When we have two point charges of opposite sign, as we move them farther and farther apart, the potential energy of this system relative to infinity will : increases

when 2 point charges of opposite sign, it will started out as negative. It will got closer and closer to zero as the particles move apart

hope this helps

What is measurements?​
Sliva [168]

Answer:

the action of measuring something.

Measurement is a comparison of an unknown quantity with a known fixed quantity of the same kind. The value obtained on measuring a quantity is called its magnitude. Magnitude of a quantity is expressed as numbers in its units.

The brachialis attaches to the forearm .035 m from the elbow at an angle of 32 deg. If the brachialis produces 750 N of force, w
jek_recluse [69]

Answer:

XY=636N

Explanation:

From the question we are told that:

Distance d=0.35m

Angle \theta=32\textdegree

Force F=750N

Generally the equation for magnitude of the stabilizing component of the brachialis force is mathematically given by

 XY=Fcos\theta

 XY=750cos 32\textdegree

 XY=636N

Given: G = 6.672 × 10−11 N · m2 /kg2 Io, a satellite of Jupiter, has an orbital period of 1.24 days and an orbital radius of 4.1
Dahasolnce [82]

Answer:

Mass of Jupiter = 4.173×10^15kg

Explanation:

Using Kepler's 3rd law, it states that the orbital period T is related to the distance,r as:

T^2 = GM/4 pi × r^3

Where G = universal gravitational constant

r = radius

M = masd of jupiter

Rearranging the formular to make M the subject of formular

T^2 × 4 pi = G M × r^3

(T^2 × 4 pi) / (G× r^3) = M

(1.24^2 × 4 × 3.142) /(6.672×10^-11)(4.11×10^8)^3

M = 19.32 /6.672×10^-11)(4.11×10^8)^3

M = 19.32 / 4.63 ×10^15

M = 4.173×10^15kg
