The water cycle is the process when water circulates from the oceans on the Earth, the atmosphere, land, this also involves rainfall and snow, sewers in rivers and streams, and then it returns to the atmosphere by evaporation and transpiration. Humans impact the water cycle by irrigation, urbanization, deforestation, and storing water in reservoirs.
Its 1.6 kg
Remember
E = 1/2mv^2 is the kinetic energy of the ball. The energy is given to you so you need to solve for mass. Rearranging the equation gives you 2E/v^2 = 1.6
4. 540 Kilometers
5. 200 s
Answer:
The volume is 5.6 L
The mass is 100.2g
Explanation:
Quantitative observations are more based on numbers and values
Answer:
7056 kJ
Explanation:
Given that,
Mass of a ship roller coaster is 36,000 kg.
It reaches a height of 20 m off the ground
We need to find the gravitational potential energy does it have. The formula for the gravitational potential energy ios given by :
E = mgh
g is acceleration due to gravity
E = 36,000 kg × 9.8 m/s² × 20 m
= 7056000 J
or
E = 7056 kJ
So, it will have 7056 kJ of gravitational potential energy.
