The weight of anything is determined on how much gravity is pulling on the object. For example a balloon full of helium floats away but iron or concrete would fall to the ground. hope this helps :)
Answer:
Biodiesel is considered a renewable energy source because it is made with animal fat
Explanation:
Biodiesel is a fuel generated from animal fats, vegetable fats, using a catalyst for chemical formulation of biodisel.
It is a renewable source of fuel, as it can be replenished (renewed) easily & in shorter time, since it is made of animal fats & vegetable fats. Unlike non renewable fuels which take long periods to replenish (renew), like fossil fuels.
So, Biodiesel is considered a renewable energy source because it is made with animal fat
To solve this problem it is necessary to use the calorimetry principle. From the statement it asks about the remaining ice, that is, to the point where the final temperature is 0 ° C.
We will calculate the melted ice and in the end we will subtract the total initial mass to find out how much mass was left.
The amount of heat transferred is defined by
Where,
m = mass
c = Specific heat
Change in temperature
There are two states, the first is that of heat absorbed by that mass 'm' of melted ice and the second is that of heat absorbed by heat from -35 ° C until 0 ° C is reached.
Performing energy balance then we will have to
Where,
= Heat absorbed by whole ice
= Heat absorbed by mass
= Heat energy by latent heat fusion/melting
Replacing with our values we have that
Rearrange and find m,
Therefore the Ice left would be
Therefore there is 0.079kg ice in the containter when it reaches equilibrium
<span>Examples of Newton's 2nd Law If you
use the same force to push a truck and push a car, the car will have
more acceleration than the truck, because the car has less mass. It is
easier to push an empty shopping cart than a full one, because the full
shopping cart has more mass than the empty one.</span>
