Answer:
<em>The amount of water in circulation is the same</em>
Explanation:
The water cycle is the pathway in which water moves from the atmosphere to the earth and back to atmosphere ones again.
During the sunny period, the temperature of the earth is heated up, water evaporates to the atmosphere as water vapour. The water vapour gathers as cloud and comes back to the earth as rain, which enters our rivers and stream. Thereby maintaining a continuous cycle.
With the water cycle, the movement of water via precipitation and evaporation is the same on earth.
Answer:22537.92 J
Explanation:
Given
mass of karen 
Distance covered by Karen =69.6 m
acceleration due to gravity=9.8
inclination
vertically karen move

h=39.72 m
Work done by escalator on karen is equal to change in potential energy of karen


Answer: The answer is option B
Explanation:
The base of the pyramid represents primary producers since they help to pass on energy to consumers as we go higher in the pyramid. They are not consumers because they supply energy and do not use up energy. They are called autotrophs.
Answer: no definite shape (takes the shape of its container)
no definite volume.
particles move in random motion with little or no attraction to each other.
highly compressible.
Explanation:
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.
Answer:
0.0299 N
Explanation:
Applying,
F = Gmm'/r²................... Equation 1
Where F = gravitational force between the boulders, m = mass of the first boulder, m' = mass of the second boulder, r = distance between the boulders, G = Universal constant.
From the question,
Given: m = 7.5×10⁶ kg, m' = 9.2×10⁵ kg, r = 124 m
Constant: G = 6.67×10⁻¹¹ Nm²/kg²
Substitute these values into equation 1
F = (6.67×10⁻¹¹× 7.5×10⁶ × 9.2×10⁵ )/124²
F = (460.23)/15376
F = 0.0299 N
