Answer:

Option (2)

Explanation:

The mountains are defined as the huge landforms that covers a large area extending above the surrounding topography, usually forming a mountain-top. They are comparatively steeper and are difficult to climb. They normally have a height more than about 2000 meters above the mean sea level. These mountains are formed due to the continuous motion of tectonic plates over the layer of asthenosphere. The high mountains are comprised of permanent ice caps at its summit that provides the water into the river through out the year.

Hence, the correct answer is option (2).

Answer:

I think it's (B)Mountain.

Explanation:

A hill is round, so not that. A plain is flat out land and a plateau is also flat so all you have left with is mountain.

Every year _______ species go extinct. a. 3 b. 72 c. 1000 d. 20000

Tems11 [23]

Well, the thing is: we don't really know, as we don't even know how many species there are on earth.

If we take a look at the estimates of World Wide Fund for Nature, an organization that works toward combating species extinction, their estimates vary from 200 to 100 000 - but a probable number is 20 000 (d).

According to william james, the purpose of psychology was to ________.

masya89 [10]

According to William James, the purpose of psychology was to "study the function of behavior".

William James is known to be the first to offer a course of psychology in US. He also remains a popularly read philosopher, and his hypotheses on pragmatism have contributed both to the field of psychology and philosophy. As per James' pragmatism, the estimation of a thought is reliant upon its helpfulness in the real world as opposed to its outright truth.

We have assumed the distance to be 0.1 meters (not millimeters) since the question has issues when expressing the units

Answer:

$d=0.60\ m$

Explanation:

Energy Conversion

We need to understand and apply the concepts of energy conversion to solve this problem. Three types of energy are manifested in the motion of the ice cube of mass m.

When it's above the ground level at a height h, it has potential gravitational energy, given by

$U=mgh$

If the cube is moving at speed v, it has kinetic energy, given by

$\displaystyle K=\frac{1}{2}mv^2$

Finally, when it compresses the spring, it has elastic energy:

$\displaystyle E=\frac{1}{2}kx^2$

Where x is the distance of compression and k is the spring constant

When the ice cube is released, it has potential gravitational energy which magnitude we cannot calculate since we don't have the height. Then it goes down the slope and acquires speed and kinetic energy until it stops when compressing the spring a distance x. In that very moment, the total energy is stored in its elastic form:

$\displaystyle E=\frac{1}{2}25\cdot 0.1^2=0.125\ J$

When the ice cube travels up powered by that energy, it has both kinetic and potential energies, and it stops up in the ramp and starts reversing direction when it runs out of speed, thus the total potential energy is

$mgh=0.125\ J$
