The Passive solar heating uses free free heating direct from the sun to reduce the estimated forty percent of energy consumed in the average australian home for space heating and cooling. many heating and cooling design objectives overlap but different emphasis is required depends on your climate need.
Through the tilt of the earth
For this question we can use the combined gas law equation.
for a fixed amount of gas
where P - pressure , V - volume , T- temperature and k - constant
Where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
temperature in K
T1 = 12 °C + 273 = 285 K
T2 - 16 °C + 273 = 289 K
substituting the values in the equation
V = 1.00 mL
Answer:
*he force to climb a plane inlcinado with constant velicad is equal to the cosine of the weight of the body
*he force to climb a plane inlcinado with constant velicad is equal to the cosine of the weight of the body
Explanation:
When a car is going up an inclined plane with constant speed, we can solve the problem using the translational equilibrium equation
Let's locate one axis parallel to the plane and the other perpendicular
F - W x = 0
F = W cos tea
therefore wes ee that the force to climb a plane inlcinado with constant velicad is equal to the cosine of the weight of the body
Work is defined by
W = F. l
in this case the force and displacement are constant
W = F L
where L is the length of the plane
W = mgL cos tes
we see that the work is equal to the cosine of the force times the distance on the plane
The water is already at its boiling point
, therefore we don't need additional heat to increase its temperature. Instead, we have to give the heat necessary to make it evaporate. The energy needed is equal to
where
m is the mass of the water
Lv is the latent heat of evaporation
The latent heat of evaporation of water is
, and the mass of this sample of water is
, therefore the heat needed to vaporize the water is
