Answer:
A) 1000 joules
Explanation:
In general work is given by the equation:
(1)
A) With the displacement and
the force applied, because the force and the displacement are parallel (the crate is pushed horizontally)
is simply
, and because the path is a straight line and the force is constant work is:
(2),
B) The work-energy theorem says that the total work on a body is equal to the change on kinetic energy:
(3)
The total work on the crate is the work done by the push and plus the work of the friction (4) , as (A) because forces are parallel to the displacement
(5) and
(6), the due friction always has negative sign because is opposite to the displacement, using (6), (5) and (4) on (3):
(3)
C) The energy is lost by friction, so the amount of energy turned into heat is the work the friction does:
(3)
Answer:
<em>The total mass of the solution should be 107 grams</em>
Explanation:
<u>Solutions</u>
A solution is a homogeneous mixture consisting of a solute dissolved into a solvent. The solute is the substance that is being dissolved, while the solvent is the dissolving medium.
The relationship between the masses is:
Where:
ms = mass of the solution
mo = mass of the solute
mv = mass of the solvent
If you were to mix mo=7 gr of sugar into mv=100 gr of water, then the total mass of the solution should be:
The total mass of the solution should be 107 grams
