Is there any absolute rest or motion? Describe the types of motion with one example of each type

1 answer:

6 0

A body is said to be at absolute rest when that object is in the state of stationary. Absolute motion means a motion that does not depend on anything external to the moving object for its existance.

Absolute motion is motion that does not depend on anything external to the moving object for its existence or specific nature. Absolutists hold that there are many motions that appear the same no matter from what reference frame they are observed.

A 795-loop square armature coil with a side of 10. 5 cm rotates at 70. 0 rev/s in a uniform magnetic field of strength 0. 45 t.

Agata [3.3K]

The rms voltage output of the generator is 1.94 × 10⁻ ⁵ V.

RMS is an acronym for root mean squared. An RMS value is more than just the "amount of AC power that causes the same heating impact as an analogous DC power" or something along those lines.

No. of loop = 795

Diameter of the coil = 10.5 cm

Radius of the coil = 5.25 cm

Magnetic Field, B = 0.45 T

Time, t = 70.0 rev/s

$V_{rms} =\frac{NwAB}{\sqrt{2} }$

Where,

N = No. of loop

A = Area of the coil

B = Magnetic Field

$V_{rms}$ = Voltage rms

Area of the coil = πr²

= 86.57 cm²

w = 2π/t

=( 2 × 3.141)/70.0

= 0.089

$V_{rms} =\frac{795*0.089*86.57* 0.45}{\sqrt{2} }\\\\V_{rms} =\frac{2756.36}{\sqrt{2} }\\\\\\V_{rms} =\frac{2756.36}{1.414 }\\\\V_{rms} = 1.94 * 10^-^5 V$

Therefore, the rms voltage output of the generator is 1.94 × 10⁻ ⁵ V.

Which materials produce greater or fewer vibrations on a roller coaster?

mixer [17]

Steel materials produce less vibrations whilst less dense and more malleable parts produce more vibrations, e.g. the wooden part of the coaster itself.
