Answer:The amount of current flowing

Explanation:this derives from amperes law of maxwell’s equations. It’s easiest to see in differential form. The curl of the magnetic field is proportional to the current plus the change (time derivative) in electric field

How do odd-shaped ceilings, decorative panels, draperies, and glass windows affect echo and noise?
vesna_86 [32]
I think they decrease echo and reduce noise, they do this by either absorbing vibrations or by scattering the sound so that echoes arrive at different times rather than reverberating as a standing wave. An echo is a reflection of a sound that arrives at the listener with a delay after the direct sound. The delay is usually proportional to the distance of the reflecting surface from the source and the listener.

The normal formula to find force is F = m* a. What kind of math do you need to do
Oduvanchick [21]
To find the Mass of an object, you need to apply division.
Since Resultant Force = Mass X Acceleration

To find mass,
Mass = Force / Acceleration

Two long, straight wires are parallel and 26 cm apart.
mezya [45]

Answer: 2.49×10^-3 N/m

Explanation: The force per unit length that two wires exerts on each other is defined by the formula below

F/L = (u×i1×i2) / (2πr)

Where F/L = force per meter

u = permeability of free space = 1.256×10^-6 mkg/s^2A^2

i1 = current on first wire = 57A

i2 = current on second wire = 57 A

r = distance between both wires = 26cm = 0.26m

By substituting the parameters, we have that

Force per meter = (1.256×10^-6×57×57)/ 2×3.142 ×0.26

= 4080.744×10^-6/ 1.634

= 4.080×10^-3 / 1.634

= 2.49×10^-3 N/m

REY [17]

A superheated cloud of gas and dust swirling around a massive object (usually a black hole or neutron star) is called an accretion disk. The correct option is c.

<h3>What is accretion disk?</h3>

Accretion disk is a heavy object surrounded by flow of gas, plasma, dust, or particles.  The materials surrounding the heavy object orbiting in the gravitational field of the object that loses energy and angular momentum as it slowly spirals inward.

This cloud can reach incredible speeds and temperatures as gravity causes it to build up more and more friction, eventually releasing x rays.

Thus, accretion disk is a superheated cloud of gas and dust swirling around a massive object.
