Answer: Tropical Zone

The tropical climate zone stretches from the Tropic of Cancer at 23.5 degrees north latitude to the Tropic of Capricorn at 23.5 degrees south latitude, with the equator centered within this zone. Climate within the tropical zone varies from the tropical wet regions of the rain forest, to the drier arid and semi-arid climate of north Africa or central Australia. Within the tropical wet zone, the weather remains hot and muggy, with frequent rainfall and little temperature variation. The arid and semi-arid regions experience wet, warm summers and cooler, drier winters, with much greater temperature variation than the tropical wet zone.

Temperate Zone

Extending from the southern edge of the Arctic Circle to the Tropic of Cancer in the northern hemisphere, and the northern edge of the Antarctic Circle to the Tropic of Capricorn in the southern hemisphere, the temperate climate zone falls between 23.5 degrees and 66.5 degrees north and south latitudes. Temperate climate zones experience warm to hot summers and cool winters, with the greatest temperature variations throughout the year of any climate zone. Climate within the temperate regions ranges from the cold, snowy winters of New England to the balmy, moderate weather associated with the Mediterranean or Southern California. Much of the United States, Europe and the southern half of South America fall within this climate zone.

Polar Zone

The polar climate zones fill the areas within the Arctic and Antarctic Circles, extending from 66.5 degrees north and south latitude to the poles. Characterized by a short, cool summer and long, bitterly cold winter, the polar zone features frequent snowfall, particularly during the winter months. The far northern portions of Canada, Europe and Russia fall within this climate zone. Farther north and south, the ice caps that make up Greenland and Antarctica represent a sub-zone of the polar climate region known as the ice cap zone. Within the ice caps, temperatures rarely, if ever, rise above freezing, even during the warmest months of the years.

11. Scientists put a sample of water into a sealed tank. Water can be a solid, liquid, or gas. At first, the water was a liquid.

leva [86]

Answer:

c . slower and started moving in place.

Explanation:

Matter can exist generally in three phases, as a solid, liquid or gas. But it can be transformed from one phase to another by the removal or application of heat energy.

The water was initially in a liquid form in the sealed tank until energy was transferred out of the substance. Thus, this causes a change of state in which the water turns to a solid. Whereby during the process, the molecules of the water moved slowly until they are fixed at a point, and vibrates individually at their individual point.

Therefore the molecules of water moved slower and stated moving in place (i.e vibrating at a point). The water turns to an ice.

Using diagram differentiate between solenoid and a toroid

damaskus [11]

The Toroid is form when you have wound conductor around circular body. In this case you have magnatic field inside the core but you dont have any poles because circular body dont have ends. This can be used where you want minimum flux leakage and dont need magnatic poles. i.e. toroidal inductor, toroidal transformer.

The Solenoid is forn when you wound conductor around body with limb. In this case magnatic field creates two poles N and S. Solenoids have little bit flux leakage. This used where you want magnatic poles and flux leakage is not an issue. i.e. relay, motors, electromagnates.

1 == toroid

2= solenoid

An object has the acceleration graph shown in (Figure 1). Its velocity at t=0s is vx=2.0m/s. Draw the object's velocity graph fo

timama [110]

Answer:

Explanation:

We may notice that change in velocity can be obtained by calculating areas between acceleration lines and horizontal axis ("Time"). Mathematically, we know that:

$v_{b}-v_{a} = \int\limits^{t_{b}}_{t_{a}} {a(t)} \, dt$

$v_{b} = v_{a}+ \int\limits^{t_{b}}_{t_{a}} {a(t)} \, dt$

Where:

$v_{a}$ , $v_{b}$ - Initial and final velocities, measured in meters per second.

$t_{a}$ , $t_{b}$ - Initial and final times, measured in seconds.

$a(t)$ - Acceleration, measured in meters per square second.

Acceleration is the slope of velocity, as we know that each line is an horizontal one, then, velocity curves are lines with slopes different of zero. There are three region where velocities should be found:

Region I (t = 0 s to t = 4 s)

$v_{4} = 2\,\frac{m}{s} +\int\limits^{4\,s}_{0\,s} {\left(-2\,\frac{m}{s^{2}} \right)} \, dt$

$v_{4} = 2\,\frac{m}{s}+\left(-2\,\frac{m}{s^{2}} \right) \cdot (4\,s-0\,s)$

$v_{4} = -6\,\frac{m}{s}$

Region II (t = 4 s to t = 6 s)

$v_{6} = -6\,\frac{m}{s} +\int\limits^{6\,s}_{4\,s} {\left(1\,\frac{m}{s^{2}} \right)} \, dt$

$v_{6} = -6\,\frac{m}{s}+\left(1\,\frac{m}{s^{2}} \right) \cdot (6\,s-4\,s)$

$v_{6} = -4\,\frac{m}{s}$

Region III (t = 6 s to t = 10 s)

$v_{10} = -4\,\frac{m}{s} +\int\limits^{10\,s}_{6\,s} {\left(2\,\frac{m}{s^{2}} \right)} \, dt$

$v_{10} = -4\,\frac{m}{s}+\left(2\,\frac{m}{s^{2}} \right) \cdot (10\,s-6\,s)$

$v_{10} = 4\,\frac{m}{s}$

Finally, we draw the object's velocity graph as follows. Graphic is attached below.

7. Which best describes the energy change th pushes a large rock down a hill?

svlad2 [7]

Answer:

Explanation:

Gravitational Energy is the energy of position or place. A rock resting at the top of a hill contains gravitational Potential energy. Hydropower, such as water in a reservoir behind a dam, is an example of gravitational potential energy.
