A circuit has a current of 1.2 A. If the voltage decreases to one third of its original amount while the resistance remains cons

tant, what will be the resulting current?

When resistance is constant, current is proportional to voltage. When 1/3 the voltage is applied, 1/3 the current will result.

(1/3)*(1.2 A) = 0.4 A

The resulting current will be 0.4 A.

In Physics what type of distance is used in calculating work?
Valentin [98]
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton. meter (N. ... One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m

Two particles in a high-energy accelerator experiment are approaching each other head-on, each with a speed of 0.9520c as measur
Over [174]

Answer:

the magnitude of the velocity of one particle relative to the other is 0.9988c

Explanation:

Given the data in the question;

Velocities of the two particles = 0.9520c

Using Lorentz transformation

Let relative velocity be W, so

v_r = ( u + v ) / ( 1 + ( uv / c²) )

since each particle travels with the same speed,

u = v

so

v_r = ( u + u ) / ( 1 + ( u×u / c²) )  

v_r = 2(0.9520c) / ( 1 + ( 0.9520c )² / c²) )  

we substitute

v_r = 1.904c / ( 1 + ( (0.906304 × c² ) / c²) )  

v_r = 1.904c / ( 1 + 0.906304 )

v_r = 1.904c / 1.906304

v_r = 0.9988c

Therefore, the magnitude of the velocity of one particle relative to the other is 0.9988c

Newtown third law applies to blank of objects​
fomenos

Answer:

All

Explanation:

I'm not sure what you meant but Newton's third law which basically states that every action has an equal and opposite reaction applies to <em>all</em> objects. So I think the answer is all.
