Answer:

C. The brightness of the remaining light bulbs will not change

Explanation:

If the battery is assumed ideal, the voltage supplied to each of the remaining two bulbs is still 9 volts. This will drive the same current through the fixed resistance of each bulb both before and after the third bulb is removed.

How do we maintain heat in our body ?

zysi [14]

Answer:

When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

Explanation:

The system can respond to internal and external influences and make adjustments to keep your body within a degree or two of your normal. The hypothalamus and your autonomic nervous system work with your skin, sweat glands, muscles and even your blood vessels to keep your temperature normal. As in other mammals, thermoregulation is an important aspect of human homeostasis. Most body heat is generated in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. Some nuts like peanuts, almonds, cashews, pistachios, and dates are also beneficial in winter. These nuts speed up your metabolism and increase your body temperature, eventually making you feel hot.

During which phase of the moon do neap tides occur?

Fynjy0 [20]

Answer:

First Quarter and Third Quarter.

Explanation:

Tides are formed as a consequence of the differentiation of gravity due to the Moon across to the Earth sphere.

Since gravity variates with the distance:

$F = G\frac{m1\cdot m2}{r^{2}}$ (1)

Where m1 and m2 are the masses of the two objects that are interacting and r is the distance between them.

For example, seeing the image below, point A is closer to the Moon than point b, and at the same time the center of mass of the Earth will feel more attracted to the Moon than point B. Therefore, that creates a tidal bulge in point A and point B.

When the Sun and the Moon are alight with respect to the Earth, then the Sun tidal force contributes to the tidal force of the Moon over the Earth. That makes the high tides even higher (spring tides).

However, when the Sun is not in the same line than the Moon (the Moon is at 90° with respect to the Sun), then the low tides are higher and the high tides are lower. That scenario is known as neap tides.

Therefore, that happens when the Moon is at First Quarter and Third Quarter.
