How are frequency and wave period related?

1 answer:

6 0

-- The unit of frequency is "per second" (Hz), which is [reciprocal time].

-- The unit of period is "second", which is [time].

Do you see where this is going ?

'Frequency' and 'period' are reciprocals of each other.

For any wave ...

Period = (1) / (frequency) .

Frequency = (1) / (period) .

A 10cm long wire is pulled along a U-shaped conducting rail in a perpendicular magnetic field. The total resistance of the wire

soldi70 [24.7K]

Answer:

a) $v=4.0m/s$

b) $B=2.958T$

Explanation:

From the question we are told that:

Wire Length $l=10cm=>0.10m$

Resistance $R=0.35$

Force $F=1.0N$

Power $P=4.0W$

Generally the equation for Power is mathematically given by

$P=Fv$

Therefore

$v=\frac{P}{F}$

$v=\frac{4.0}{1.0}$

$v=4.0m/s$

Generally the equation for Magnetic Field is mathematically given by

$B=\frac{\sqrt{PR}}{vl}$

$B=\frac{\sqrt{4*0.35}}{4*0.10}$

$B=2.958T$

A parallel-plate capacitor with circular plates of radius R is being discharged. The displacement current through a central circ

Dvinal [7]

Answer:

The discharging current is $I_d = 36.8 \ A$

Explanation:

From the question we are told that

The radius of each circular plates is R

The displacement current is $I = 9.2 \ A$

The radius of the central circular area is $\frac{R}{2}$

The discharging current is mathematically represented as

$I_d = \frac{A}{k} * I$

where A is the area of each plate which is mathematically represented as

$A = \pi R ^2$

and k is central circular area which is mathematically represented as

$k = \pi [\frac{R}{2} ]^2$

$I_d = \frac{\pi R^2 }{\pi * [ \frac{R}{2}]^2 } * I$

$I_d = \frac{\pi R^2 }{\pi * \frac{R^2}{4} } * I$

$I_d = 4 * I$

substituting values

$I_d = 4 * 9.2$

$I_d = 36.8 \ A$

Water occupies two main fluid compartments within the body, the intracellular fluid compartment and the extracellular fluid comp

nadezda [96]

Answer:

C. Approx. Two thirds of the water is in the ICF compartment

Explanation:

The body cells are bathed in fluids internally and externally. The water inside the cells make up about 42% of the total body weight and is called the intracellular fluid (ICF). The rest of the fluid outside the cells is called extracellular fluid (ECF) and is separated from the intracellular fluid by a semipermeable membrane that surrounds the cell, and only allows fluid to flow in and out of the cells, but prevents unwanted molecules or materials from getting in.
