Explanation:

Everything occurring around us and in nature in a result of science. Right through day and night all the phenomenon occurring in nature is science.

Examples of it are :

1. When we put the milk or water in a gas stove to heat, the water or the milk starts boiling. This is because the as the temperature increases the atoms of the water or milk starts absorbing the energy and starts vibrating and colliding with the neighboring atoms, thus transferring the heat within the liquid. Thus the milk or water starts to boil.

2. The sun rises in the east and sets in the west. This is a natural phenomenon that occurs because of the rotation of the earth in its own axis.

3. Plants make food with the help of sunlight. This is a process called photosynthesis, where plants make food by absorbing energy from the sunlight and water form the soil thus producing oxygen and taking in carbon dioxide.

All these three events occurs or exists because of science.

almost everything artafitial would have been made because of science. However nothing natural would exist because of science. All science does is look around and see what's up.

"It is impossible to devise a process which may convert heat, extracted from a single
Vladimir [108]

Answer:

According to the second law of thermodynamics, we are unable to use the heat of the ocean and the atmosphere because we do not have a reservoir that has a temperature lower than the ocean or the atmosphere.

Explanation:

As you already know, the ocean and atmosphere have a lot of thermal energy, however, we are unable to convert this energy into mechanical energy that would be useful for our activities. This can be explained by the second law of thermodynamics, since it states that the presence of two bodies with different temperatures is necessary for it to be possible to transform heat into work.

In this case, to transform the thermal energy of the ocean and the atmosphere into mechanical energy we would need the existence of a thermal motor, which is only possible to be established when there is a body with high thermal energy and a sink, a reservoir, with low thermal energy, which will be the place where the heat will be expelled, to be converted into work. We do not have a reservoir with less thermal energy than the ocean and the atmosphere, so we cannot use their energy.

The double inclined plane supports two blocks A and B, each having a weight of 10 lb. If the coefficient of kinetic friction bet
Vladimir79 [104]

Answer:

Explanation:

Left block is on surface with higher inclination so it will go down . If T be tension

For motion of block A ,

net force = mgsin60 - (T + mg cos 60 x μ ) , μ is coefficient of friction .

ma =  mgsin60 - T -  mg cos 60 x .1

10a = 277.13  - T - 16

= 261.13 - T

T = 261.13 - 10a

For motion of block B

T - mg sin30 - mgcos30 x μ = ma

T- 160 - 27.71 = 10 a

261.13 - 10a - 160 - 27.71 = 10a

73.42 = 20a

a = 3.67 ft / s²

common acceleration = 3.67 ft / s²
