<span>Janice saw her older sister get into trouble for breaking curfew and decided she'll never do the same. Because she is learning from her older sisters mistakes!
Hope this helps!!</span>

Feces is usually about 40 percent water and 60 percent solid matter. Reducing the water content to 20 percent would most likely

Licemer1 [7]

Answer:

Constipation

Explanation:

An organism's bowel movement depends on the amount of water it has consumed. If the organism has not consumed enough water then the stool becomes hard and dry.

This makes it difficult for the organism to pass the stool. This condition is known as constipation.

Hence, here if the water content is reduced to 20 percent then this would likely result in constipation.

If the current in a wire of a cd player is 12.0 ma, how long would it take for 6.50 c of charge to pass a point in this wire? an

Galina-37 [17]

The current intensity is defined as the amount of charge Q that passes through a certain point of an electrical wire in a time interval of $\Delta t$ :
$I= \frac{Q}{\Delta t}$

In our problem, the current intensity is
$I=12.0 mA=0.012 A$
while the amount of charge that passes a certain point of the wire is
$Q=6.50 C$

If we re-arrange the previous equation:
$\Delta t= \frac{Q}{I}$
we can find the time needed for this amount of charge to pass through a point of the wire:
$\Delta t= \frac{6.50 C}{0.012 A} =541.7 s$

Two circular coils are concentric and lie in the same plane. The inner coil contains 110 turns of wire, has a radius of 0.014 m,

Hatshy [7]

Answer:

The current flowing through the outer coils is

Explanation:

From the question we are told that

The number of turn of inner coil is $N _i = 110 \ turns$

The radius of inner coil is $r_i = 0.014 \ m$

The current flowing through the inner coil is $I_i = 9.0 \ A$

The number of turn of outer coil is $N_o = 160 \ turns$

The radius of outer coil is $r_o = 0.022\ m$

For net magnetic field at the common center of the two coils to be zero the current flowing in the outer coil must be opposite to current flowing inner coil

The magnetic field due to inner coils is mathematically represented as

$B_i = \frac{N_i \mu I}{2 r_i}$

The magnetic field due to inner coils is mathematically represented as

$B_o = \frac{N_o \mu I_o}{2 r_o}$

Now for magnetic field at center to be zero

$B_o = B_i$

$\frac{N_i \mu I_i}{2 r_i} = \frac{N_o \mu I_o}{2 r_o}$

=> $\frac{110 * 9}{2 * 0.014} = \frac{160 *I_o}{2 0.022}$

$I_o = 9.72 \ A$

If Earth's obliquity was 157 degrees, would the seasons be more severe, less severe, or about the same?

ikadub [295]

The severity of the seasons on Earth is given not by the distance Earth-Sun but by the tilt of the Earth axis. This happens because that the sun rays are oblique in winter and perpendicular in summer (thus the same quantity of sun rays heats a bigger surface in winter - oblique rays).
The present tild of the Earth axis is 23.5 degrees (from the vertical). If the axis were tilt at 157 degree this would be equivalent to 180-157 =23 degree. Thus the severity of the seasons would be approximately the same but the seasons would be reversed (for example instead of winter we would have summer, instead of summer we would have winter).

Always, whether we notice it or not. It's a law of nature.
