What layer of the atmosphere contains all of the weather and thus the most water vapor?

Veronika [31]

The troposphere is the lowermost layer of the Earth's atmosphere. Most of the weather phenomena, systems, convection, turbulence and clouds occur in this layer, although some may extend into the lower portion of the stratosphere.

xeze [42]

The question is incomplete. Here is the complete question:

A whale swims due east for a distance of 6.9 km, turns around and goes due west for 1.8 km and finally turns around again and heads 3.7 km due east. (a) What is the total distance traveled by the whale? (b) What are the magnitude and direction of the displacement of the whale?

Answer:

(a) Distance = 12.4 km

(b) Displacement = 8.8 km due east

Explanation:

Consider east direction as positive and west direction as negative.

Given:

The motion is along the east-west line.

The whale first swims 6.9 km due east, then 1.8 km due west and again 3.7 km due east.

(a)

Distance traveled by the whale is equal to the sum of the lengths of all the distances traveled. Therefore,

Distance traveled = 6.9 km + 1.8 km + 3.7 km = 12.4 km

Therefore, the distance traveled by the whale is 12.4 km.

(b)

Displacement of the whale is given by considering the sign of each of the individual displacements. Therefore,

Displacement of the whale = (+6.9 km) + (-1.8 km) + (+3.7 km)

Displacement of the whale = 6.9 km - 1.8 km + 3.7 km = 8.8 km

The answer is positive. So, the direction is due east.

Therefore, the displacement of the whale is 8.8 km due east.

What’s Is Example Of

ahrayia [7]

*heat transfer energy, As it always flow from higher temperature to lower temperature till it reach the thermal equilibrium.

example: -friction.

- collisions.

- the hot cup which's hotter than your hand✋will transfer heat in your hand. and a cold piece of ice which's colder than your hand to causing the heat transfer out of your hand .

*temperature ️ depends on the move of particle and we have a different shape of motion like:

translational motion.

rotational motion.

vibrational motion.

when the temperature:

increases it has more kinetic energy and faster moving particles and the object expanded which known as (thermal expansion).

decreases it has less kinetic energy and slower moving particles.

As kinetic energy is 1/2 mV².

example: -the mercury in thermometers.

*Absolute zero :

The theoretical temperature at which substances possess no thermal energy, equal to 0 K, −273.15°C, or −459.67°F.

*specific heat "c" :

is essentially a measure of how thermally insensitive a substance is to the addition of energy.

c=Q/m∆T

where Q is energy .

note water has a higher specific heat, and lower temperature.

*conduction example When the stove is turned on, the skillet becomes very hot due to the conduction of heat from the burner to the skillet.

Which of the following phenomena are due to the electric interaction? (Select all that apply.) surface tension in water friction

Eddi Din [679]

Answer:

Surface tension in water

Friction between tires and pavement

Dissolution of salt in water

Explanation:

Surface tension in water: It is due to the electrostatic force of attraction (cohesive force) between water molecules.

Friction between tires and pavement: It is due to the attractive force between tires and pavement.

Dissolution of salt in water: The ions of $Na ^ +$ and $Cl ^ -$ separate due to the strong attraction of water molecules.
