The total amount of energy per hour is 
Explanation:
In this problem we are told that the amount of energy reaching a square meter in the United States per hour is

The total surface area of the United States is

And converting into squared metres,

Therefore, the total energy reaching the entire United States per hour is given by:

1.Life science involves fields of discipline catering to living organisms such as we humans while physical science caters to non-living organisms.
2.Life science has more fields of discipline than physical science.
3.Physical science relies on laws and theories to explain concepts while life science relies on biological explanations and can also rely on theories.
Answer:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
Explanation:
The general kinematic equation for horizontal displacement is gives as:
Δx = v₀t + (1/2)at²
Where
Δx = change in the x direction
v₀ = initial velocity
t = time
a = acceleration
If the body is vertically instead of horizontally, Δx is changed to Δy
Δy = v₀t + (1/2)at²
For a vertical moving body, the acceleration it experiences is the gravitational accerelation of the earth 'g'
So the equation becomes:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
Answer:
When the heat is heated it will be melted of ice, why it still remain at a constant temperature of 0◦ C.
Explanation:
Solution
The heat given by the heater will be used in melting of the ice, therefore the temperature will remain the same at the degree of 0◦ C.
After the ice is fully melted, the temperature of water will begin to increase with time.
