Two magnets are sliding towards each other. One of the magnets, which has a mass of 125 grams, is moving in the positive x-direc
olasank [31]

Answer:

0.45 m/s in the negative x-direction

Explanation:

From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum

Momentum, p=mv where m is the mass and v is the velocity

m_1v_1+m_2v_2=(m_1+m_2)v_c where v_c is the common velocity, v_1 and v_2 are velocities of magnet moving in positive x-direction and magnet moving in negative x-direction respectively, m_1 and m_2 are masses of magnet moving in positive x-direction and magnet moving in negative x-direction respectively.

Substituting 125 g for m_1 and 85 g for m_2, 7.33 m/s v_1, -11.9 m/s for v_1 then

125 g\times 7.33 m/s + (85 g\times -11.9)=(125 g+ 85 g)\times v_c

-95.25 g. m/s=210 g v_c

v_c=\frac {-95.25 g.m/s}{210 g}=-0.453571429 m/s&#10;\approx -0.45 m/s

Therefore, the velocity of single unit is 0.45 m/s in the negative x-direction

The Earth possesses an electric field of (average) magnitude near its surface. The field points radially inward. Calculate the n
IgorLugansk [536]

Answer:

Incomplete question

This is the complete question

The Earth possesses an electric field of (average) magnitude 150 near its surface. The field points radially inward. Calculate the net electric flux outward through a spherical surface surrounding, and just beyond, the Earth's surface.

Explanation:

Given that,

Electric field is 150N/C inward

i.e E = - 150 i

Then, electric flux (Φ) is given as

Φ=∮E.dA

Surface area of a sphere is

A=4πr²

dA=8πr dr

The area is outwardly i.e

dA=-8πr dr i

Φ=∮E.dA

Φ=∮-150 i • 8πr i dr from 0 to R

Φ= -1200π∮rdr. From 0 to R

Φ= -1200π r²/2. From 0 to R

Φ= -600π [R² -0²]

Φ= -600πR²

Where R is radius of earth which is 6,400,000m

Φ= -600πR²

Φ= -600π(6400000)²

Φ= -7.72×10^16 Nm²/C

Overtime how did matter and energy in a system naturally change in physics
Phantasy [73]
The movement of energy and matter in a system differs from one system to another. ... On the other hand, in open system both the matter and energy move into and out of the system. Therefore, matter and energy in a system naturally change over time will decrease in entropy. Hope this helped
