6 0

Answer:

Motion - zero displacement. A tram leaves the depot, travels along its route and returns back to the depot. The tram has covered a total of 80km but its displacement is 0km since it ends up where it started. A cart moves along a straight track for 50m.

Which of these biomes receives the least amount of rainfall every year?
ASHA 777 [7]

Answer:

Desert

Explanation:

The desert receives the least amount of rainfall yearly.

A desert can be described a barren area of land where little amount of rainfall occurs and, because of this, living conditions are not favourable for plants and animal life. Because there is no vegetation in a desert, the bare surface of the ground are subjected to denudation.

Calculate the work performed by an ideal Carnot engine as a cold brick warms from 150 K to the temperature of the environment, w
olga nikolaevna [1]

To solve this problem, apply the concepts related to the calculation of the work performed according to the temperature change (in an ideal Carnot cycle), for which you have to:

W = \int\limit_{T_c}^{T_H} C (1-\frac{T_H}{T})

Where,

C = Heat capacity of the Brick

T_C= Cold Temperature

T_H = Hot Temperature

Integrating,

W = C (T_H-T_C)- T_H C ln (\frac{T_H}{T_C})

Our values are given as

T_H= 300K

T_C = 150K

Replacing,

W = (1) (300-150)-300(1)ln(2)

W = 150-300ln2

W = -57.94kJ \approx 58kJ

Therefore the work perfomed by this ideal carnot engine is 58kJ

What would happen if the amount of light reaching the Earth from the sun were cut in half? Predict what the climate and life wou
kicyunya [14]
A lot would happen depends on which perspective you look at it from. Less incoming solar radiation means that there is a greater possibility of the surface temperature of earth reducing. there would be a cooling effect. And it could be major cooling in certain part of the world depending on milankovitch cycles. We know that the amount of light or solar radiation that reaches the earth is unequal in different parts of the world because of the obliquity, eccentricity, and precession of the earth. But, in general you would most likely see a cooling trend around the world and in some parts it would be extreme. In Canada or in the North is general, winters would become even more cooler or colder... winters would become longer perhaps, And summers would 've cooler. on the contrary to what most believe, you would most likely see a decline in precipitation such as snow or rain because this is mostly caused or intensified by warming temperatures. Life would be probably very similar to that of the Pleistocene epoch. how would humans respond to this change... Well most likely they would try to use their tech to control weather because they already do to a smaller proportion.

hope that helps a bit! :)
